Integration Testing vs Functional Testing: Key Differences

UpendraPrasadMahto — Tue, 09 Jan 2024 07:32:34 +0000

Software Testing plays an essential role in the world of software development. It connects the bridge between innovation and reliability. It ensures that the software meets industry standards and exceeds user expectations. With the advancement in technology and the increasing demands of users, software testing has become a fundamental and indispensable practice.

The main objective of this blog is to explore key differences between Integration Testing and Functional Testing. We will look at its workflow, advantages, disadvantages, when to use it, key differences, and use cases.

What is Integration Testing?

Integration testing is software testing where software modules are gradually integrated and then tested as a unified group. This testing ensures that all modules interact correctly and without flaws and errors. The modules must be tested independently before being tested together; hence, unit testing must be performed before integration testing.

Integration testing uses grey box testing techniques, combining white box testing and black box testing. There are various ways to perform integration testing, such as top-down, bottom-up, sandwich, big-bang, and incremental approaches.

The main objectives of integration testing are:

Interaction Check: It verifies that different modules of the software work as expected when combined.
Issue Discovery: It looks for hidden problems arising when these modules interact.

Learn more about integration testing in detail.

Workflow

The integration testing workflow is visually represented in the image below.

With our reliable HTML to YAML converter, you can quickly and easily convert your HTML files to YAML format in just a few clicks and and increase productivity.

From the above image, we may conclude the workflow as follows:

Understand and verify the requirements and specifications.
Prepare a test plan by identifying entry and exit points.
Create a traceability matrix through analysis and planning.
Select the best testing approach based on application needs.
Design various test cases and scripts for integration testing.
Compare actual results with expected output for validation.

Advantages of Integration Testing

The following are the advantages of integration testing:

Integration testing allows you to test important scenarios that can only be verified when all system modules are combined.
Integration testing provides a structured approach to assembling a software system and running tests, efficiently uncovering errors related to component interactions.
You don’t have to wait for all individual modules to complete unit testing before integration testing can begin.
It is important to confirm whether software modules work cohesively and in unity, which is crucial for seamless system functionality.

Disadvantages of Integration Testing

The following are the disadvantages of integration testing:

Integrating different modules can be complex and time-consuming, especially for large and complicated systems.
It can delay development, especially when integration problems require extensive troubleshooting.
Identifying the root cause of integration problems can be more challenging than unit testing, where problems are usually limited to a specific component.
It may require substantial hardware, software, and test environments, making it resource-intensive.

Use Cases of Integration Testing

The following are the uses of integration testing:

It ensures that APIs work seamlessly together, enabling data exchange and communication between software services.
It helps to check the interaction between the software and the database.
It helps to test the integration of third-party APIs and services, such as payment gateways or social media logins. Also, it ensures that they work smoothly with the main application.
It helps test the software performance on different platforms like mobile devices, web browsers, or operating systems.

When to Perform Integration Testing

Integration testing is performed after unit testing and before functional testing. Unit testing involves isolating individual modules to ensure their correctness and acceptance. The integration test is done once the module unit tests are completed. Integration testing examines how modules interact when combined to form a unified group. After successful integration testing, functional testing is the next phase. It assesses the entire software system to ensure it meets user requirements and functions correctly in real-world scenarios.

Let’s take a real-world scenario as an example.

Suppose you’re building an e-commerce platform with various interconnected modules — a product catalog, a shopping cart, and a payment gateway. Each module is developed independently, ensuring they work flawlessly in isolation.

To guarantee a smooth shopping experience, you want to ensure these modules work correctly. The workflow should be: a customer browsing the product catalog, adding items to the shopping cart, and successfully making a payment.

This involves checking whether the product details are correctly transferred from the catalog to the cart. The payment gateway securely processes the transaction if the cart accurately matches the costs. Integration testing ensures that these modules interact correctly without any error.

What is Functional Testing?

Functional testing is a black-box testing technique in which the software is tested to verify that it works as expected in real-world situations. It evaluates a software system by examining whether it meets all specific requirements and expectations, such as user interface, database, APIs, client/server communication, security, and other crucial components. It includes various tests such as smoke testing, acceptance testing, sanity testing, regression testing, etc.

The main objectives of functional testing are:

Verify Correctness: Ensure software functions according to documented requirements and performs tasks accurately and effectively.
Detect Defects: Identify deviations from expected behavior or software functionality errors.

Learn more about functional testing in detail.

Workflow

The functional testing workflow is visually represented in the image below.

From the above image, we may conclude the workflow as follows:

Identify and understand the requirements and specifications.
Prepare and design test cases.
Create a traceability matrix through analysis and planning.
Execute the test cases.
Validate the results by comparing actual results with expected output.

Advantages of Functional Testing

The following are the advantages of functional testing:

Functional testing ensures software meets user expectations by testing individual functions against specified requirements.
It reduces and resolves software defects and prevents problems before they become critical.
It verifies that each software function performs as intended, resulting in a more reliable and bug-free product.
It saves costs by detecting functional issues early and preventing defects from propagating through later stages of development.

Disadvantages of Functional Testing

The following are the disadvantages of functional testing:

This may only cover some lines of code or all possible scenarios, leaving some parts of the software untested.
It mainly focuses on what the software is supposed to do and generally neglects non-functional aspects such as performance, security, and scalability.
With functional testing, it can be difficult to discover all problems.
It can be resource-intensive, requiring time, effort, and a range of test scenarios.

Use Cases of Functional Testing

The following are the uses of functional testing:

It helps identify and fix software deficiencies, bugs, and errors to improve reliability and quality.
It helps verify software performance under various configurations, loads, and environments to ensure reliable functionality.
It helps in testing the software to prevent new problems when implemented changes or updates are introduced.

When to Perform Functional Testing

Functional testing after integration testing may coincide with system testing, depending on the software development methodology. Functional testing occurs after unit testing, which evaluates individual modules in isolation, and integration testing, which verifies the interactions between those modules.

Let’s take a real-world example of functional testing by considering a mobile banking application.

User Authentication: In this, you want to check whether you securely log in to their mobile banking accounts. Here, the testers validate that the login credentials are correctly verified and ensure users can access their accounts securely.
Balance Inquiry: In this, you want to check account balances and transaction history. Here, the testers perform balance inquiries, verifying that account balances and transaction histories are accurately displayed and any transactions are updated immediately.

How To Check Proxy Settings: Know If You Leave Digital Footprints Behind

UpendraPrasadMahto — Fri, 01 Dec 2023 10:17:30 +0000

In today’s digital era, the security and privacy of data and digital footprints are essential. Proxies are the secret agents that enable you to hide your IP address, access geo-restricted content, and prevent malware and phishing attacks on your device directly.

In most organizations, proxies are used widely by network administrators to monitor and filter incoming and outgoing web traffic from employees or clients. The use of proxy servers sets up these proxies.

To configure the proxy servers, network administrators use the Proxy settings. This article’ll show you how to check proxy settings (if your computer uses a proxy server) on various platforms.

What is a Proxy Server?

A proxy server is an intermediary between a machine and the ISP(Internet Service Provider) that forwards requests and responses. When you want to access a website or online service, your computer doesn’t talk directly to the web; instead, it communicates with the proxy server, which then passes your request along to the internet and returns the responses to your computer.

What is Proxy Settings?

Proxy settings refer to the setup that guides the communication process between the ISP and the proxy server. It’s like a set of rules that tell your computer how to interact with the proxy server. This configuration determines the path your online requests and responses should take and allows you to customize your internet experience for things like privacy security or bypassing certain restrictions.

Proxy settings include the following:

Proxy Server Address: This is the IP address or hostname of the proxy server that the device should connect to. It identifies where the proxy server is located on the network.
Proxy Port: The device’s port number should connect to the proxy server. It’s important because it defines the specific communication channel to reach the proxy server.

Why Proxy Settings Matter?

Proxy settings matter for several reasons, and their significance varies depending on individual and organizational needs. The following are some reasons why proxy settings are important:

Anonymity and Privacy: Imagine you’re online, and you don’t want websites to know where you’re browsing from. Proxy servers can help with that. They act like a shield, hiding your location and identity by making it seem like your requests are coming from somewhere else. This gives you online privacy.
Content Filtering: It is also referred to as web content filtering. It is the process of controlling and managing the type of online content that users can access on a network or device. Organizations like schools, businesses, and government networks use proxy servers to manage what websites you can or can’t visit. It simply blocks access to anything they consider unsuitable.
Security: Proxy servers can inspect and monitor incoming and outgoing internet traffic. They look for anything suspicious, like viruses or malware, and keep your online space safer.
Load Balancing: It distributes network traffic across multiple proxy servers to ensure efficient utilization of resources, improve performance, and enhance redundancy. This is particularly important when the users are dealing with heavy internet traffic.

What is React?

React, commonly known as React.js or ReactJS, is an open-source JavaScript library created and managed by Meta (formerly Facebook). It serves as a fundamental tool for constructing user interfaces in web applications. Remarkably, in 2022, an impressive 82% of users favored React, according to StateofJS findings.

It uses a declarative syntax, which means you specify what you want to achieve, and it takes care of the logic to make it happen. It allows developers to describe how the user interface should look and behave at any time.

It organizes the UI into reusable components. These components are like building blocks that can be combined to create complex user interfaces. It also uses Virtual DOM to minimize the number of actual DOM manipulations, leading to improved performance.

How React Works?

React organizes a web application into reusable components, each representing a part of the user interface. These components are created and rendered based on their current state and properties. Then, React employs a virtual DOM to track changes efficiently. When events or data updates occur, React compares the new virtual DOM with the previous one, identifies necessary changes, and updates the actual DOM accordingly.

This approach minimizes direct DOM manipulation and optimizes performance. It continuously repeats this process to keep the user interface synchronized with the application’s state, providing a dynamic and interactive web application.

How does React Native Work?

In React Native, the application works with two separate threads: the JS (JavaScript) Thread and the Native Thread. The core of React Native’s code runs within the JS thread, where it handles calculations and processing. Once the calculations are complete, React Native passes the final data in JSON format to the Native Thread. This data transfer is made possible by an Async Bridge. The Native Thread then uses this data to create and display the app’s layout on the screen. This division of tasks ensures that React Native apps run smoothly and efficiently.

This is the older architecture in which the bridge has issues like it was asynchronous, single-threaded, and imposed extra overheads.

The new architecture has moved away from using the Bridge for communication and adopted a new architecture that consists of Turbo Modules — The New Native Module System, Fabric — The New Renderer and The Codegen.

Turbo Native Modules represent a significant advancement in Native Modules, providing some extra benefits. They provide consistent, strongly typed interfaces across platforms, making development more predictable. Developers can leverage C++ alongside native languages, reducing the need for redundant code. With lazy loading, applications launch faster, enhancing the user experience. The use of JSI streamlines communication, surpassing the traditional bridge for efficiency.

Fabric is a new UI layer that facilitates synchronous communication with native UI components. It offers consistent and strongly typed interfaces that work seamlessly on various platforms. It allow developers to write code in C++, either exclusively or integrated with other native languages. It also leverages JSI, a JavaScript interface for native code, enabling highly efficient communication between native and JavaScript components, surpassing the traditional bridge method for communication.

The codegen simplifies the process by generating the C++ boilerplate code required for the New Architecture using static typing in JavaScript.

We can speed up the software validation process and boost testing coverage by adopting automated testing. However, there are a lot of challenges in applying test automation. In this article on the top 9 challenges in automation testing, we look at the various obstacles and how to deal with them.

Implementing Selenium Wire in your Test Automation Framework

We have already discussed Selenium Wire, its key features, and its advantages over its competitors. It’s time to see how you can implement Selenium Wire in your test automation framework.

Before installing Selenium Wire, let’s look at some of the prerequisites.

The latest version of Python on any platform (Windows, macOS, Linux)
Appropriate WebDriver for your preferred browser (e.g., ChromeDriver for Chrome)

Step 1: Installation of Selenium Wire

The following are the steps to install the Selenium Wire.

Open a command prompt or terminal window.
Use the pip command as shown below to install the Selenium Wire library.

pip install selenium-wire

Step 2: Set Up Your Selenium Project

Ensure your Selenium project is running and you have installed all required dependencies.

Step 3: Import Selenium Wire

Import the necessary module or library that you want in your projects.

For example-

from seleniumwire import webdriver
from selenium.webdriver.common.keys import Keys

Step 4: Configure Your WebDriver

Create an instance of the webdriver class from Selenium Wire while setting up your WebDriver instance.

For example-

options = webdriver.ChromeOptions()
# Configure any desired options for the Chrome browser

# Create a WebDriver instance with Selenium Wire
driver = webdriver.Chrome(options=options)

Step 5: Write Your Test Cases

You may use the usual Selenium methods and functions to create your test scenarios. During the execution of the test, Selenium Wire will automatically intercept and collect the network traffic.

For example: Below is the code to perform a search operation on a web application.

driver.get("https://lambdatest.com")
search_box = driver.find_element_by_name("q")
search_box.send_keys("selenium")
search_box.send_keys(Keys.RETURN)

Step 6: Analyze Network Traffic

You can use Selenium Wire’s API to access the network traffic data you recorded after running your test cases.

For example, you can retrieve all requests made during the test and print their URLs and response status codes:

for request in driver.requests:
    print(request.url, request.response.status_code)

Step 7: Enhance Your Test Cases

Make use of Selenium Wire’s network traffic analysis to improve your test cases.

For example, to add a custom header to all requests made during the test, you may use this as shown below.

driver.header_overrides = {
    'User-Agent': 'Custom User Agent'
}

Step 8: Execute and Refine

You can use the Selenium Wire integrated into your framework to run your upgraded test cases. You can also utilize the knowledge collected from network traffic analysis to analyze the outcomes and improve your tests.

In this blog, we covered the top codeless Automation testing tools out there for 2021 (with features). Read now to choose the best that suits your needs.

Understanding the Request and Response Object

In Selenium Wire, the Request and Response objects play a crucial role in capturing all HTTP/HTTPS traffic made by the browser and then providing access to it. Let’s understand these objects in more detail:

Request Object

The Request object represents an HTTP request made by the web browser during test execution. It contains information about the request, such as the URL, method, headers, body content, and query parameters. You can access various properties of the Request object to examine and manipulate the captured request.

Response Object

The Response object represents the corresponding HTTP response received from the server for a particular request. It contains information such as the status code, headers, body content, and content type. You can access the properties of the Response object to analyze and extract relevant information from the captured response.

By working with these Request and Response objects in Selenium Wire, you can gain insights into the network behavior of your web application. You can examine the headers, retrieve the body content, analyze the status codes, and perform various operations to simulate different network conditions or modify the requests/responses.

Now, let’s see the attributes of request and response objects, respectively.

Attributes of the request object.

ATTRIBUTES	DESCRIPTION
body:	Represents the request body as bytes. It will be empty (b”) if there is no request body.
cert:	Contains information about the server SSL certificate in dictionary format. Empty for non-HTTPS requests.
date:	Represents the datetime when the request was made.
headers:	A dictionary-like object that stores the request headers.
host:	Represents the requesting host, For example: “www.example.com”
method:	Represents the HTTP method used in the request, such as GET, POST, etc.
params:	A dictionary of request parameters. If a parameter with the same name appears multiple times, its value in the dictionary will be a list.
path:	Represents the request path. For example: “/some/path/index.html”
response:	Represents the response object associated with the request. It will be None if the request has no response.
querystring:	Represents the query string in the request. For example: “foo=bar&spam=eggs”
url:	Represents the complete URL of the request. For example: “https://www.example.com/some/path/index.html?foo=bar&spam=eggs”.

Attributes of the response object.

ATTRIBUTES	DESCRIPTION
body:	Represents the response body as bytes. It will be empty (b’ ‘) if there is no response body.
date:	Represents the datetime when the request was made.
headers:	A dictionary-like object that stores the response headers.
reason:	Represents the reason phrase of the response. For example: “OK” or “Not Found”.
status_code:	Represents the HTTP status code of the response. For example: 200 or 404.

Intercepting HTTP Requests and Responses with Selenium Wire

Intercepting requests and responses with Selenium Wire is a powerful feature that allows you to capture and analyze network traffic during your test automation. You can learn more about how the web browser and server communicate by intercepting requests and responses. You can also alter network data and take various actions for testing.

Selenium Wire allows you to intercept and modify the Request and Response objects by adding driver.request_interceptor and driver.response_interceptor attributes before you start using the driver.

A request interceptor should accept a single argument representing the intercepted request.
A response interceptor should accept two arguments: one for the original request and another for the intercepted response.

Let’s take an example for better understanding.

In this example, we simply print the URL of the intercepted request and the status code of the intercepted response.

from seleniumwire import webdriver


# Create a new instance of the Selenium Wire WebDriver
driver = webdriver.Chrome()


# Define a request interceptor function
def my_request_interceptor(request):
    # Do something with the intercepted request
    print(f"Intercepted request: {request.url}")


# Define a response interceptor function
def my_response_interceptor(request, response):
    # Do something with the intercepted response
    print(f"Intercepted response: {response.status_code}")


# Set the request interceptor
driver.request_interceptor = my_request_interceptor


# Set the response interceptor
driver.response_interceptor = my_response_interceptor


# Make requests
#driver.get('https://www.example.com')
driver.get('https://www.google.com')


# Close the driver
driver.quit()

In the above program, we import the webdriver class from the seleniumwire module and create a new instance of the Selenium Wire WebDriver using webdriver.Chrome(). We define two interceptor functions, my_request_interceptor, and my_response_interceptor, which will be called for each intercepted request and response.

We set the request interceptor by assigning the my_request_interceptor function to the request_interceptor property of the driver. Similarly, we set the response interceptor by assigning our my_response_interceptor function to the response_interceptor property of the driver.

Optimize Selenium Requests by Blocking Requests

To optimize Selenium Wire, you can use a request interceptor to block certain requests, for example- images (in this case), to increase the speed of your scraping or automation tasks and reduce bandwidth consumption. This improves performance and efficiency.

from seleniumwire import webdriver
from selenium.webdriver.common.by import By
from seleniumwire import request


# Set up Chrome driver options
options = webdriver.ChromeOptions()


# Create an instance of the Chrome driver
driver = webdriver.Chrome(options=options)


# Define a request interceptor function
def request_interceptor(request):
    # Block image assets
    if request.path.endswith(('.png', '.jpg', '.gif')):
        request.abort()


# Set the request interceptor
driver.request_interceptor = request_interceptor


# Hit the target site
driver.get('https://lambdatest.com')


# Find and print the body content
body = driver.find_element(By.TAG_NAME, 'body')
print(body.text)


# Quit the driver
driver.quit()

Our primary goal is to extract and collect text-based information while disregarding other forms of content. The image below illustrates the textual data that can be observed.

In this Selenium JavaScript for Automation testing tutorial, as we deep dive into the basic concepts, explained the best practices and executed automation scripts with JavaScript on cloud-based Selenium Grid.

Performing a GET Request

A GET request is a method of retrieving data from a data source using the internet.

To perform GET requests to a webpage using Selenium Wire, you may follow the below steps:

Import the ‘webdriver’ module from ‘seleniumwire’ and create a new instance of the Chrome web driver.
Access the requests made by the browser using the ‘requests’ property of the driver.
Iterate through the requests and perform the desired actions, such as printing the URL and status code of each request (In my case).
Finally, close the web driver using the ‘quit’ method.

You may refer to the below program for a better understanding.

from seleniumwire import webdriver


# Create a new instance of the Chrome web driver
driver = webdriver.Chrome()


# Perform a GET request to a webpage
driver.get('https://www.google.com/search?q=lambda+test&tbm=isch&ved=2ahUKEwj5yoy0raL_AhWNF7cAHSfBCoYQ2-cCegQIABAA&oq=lambda+test&gs_lcp=CgNpbWcQAzIFCAAQgAQyBQgAEIAEMgUIABCABDIFCAAQgAQyBggAEAUQHjIGCAAQCBAeMgYIABAIEB4yBggAEAgQHjIGCAAQCBAeMgYIABAIEB46BAgjECc6BwgAEIoFEEM6BwgjEOoCECc6CAgAEIAEELEDUABYgihgpyxoAXAAeASAAbcBiAGnEpIBBDAuMTaYAQCgAQGqAQtnd3Mtd2l6LWltZ7ABA8ABAQ&sclient=img&ei=6bR4ZLmyK42v3LUPp4KrsAg&bih=746&biw=1536&rlz=1C1CHBF_enIN893IN893#imgrc=5gZQH7pNd8B6lM')


# Access the requests made by the browser
for request in driver.requests:
    if request.response:
        print(request.url, request.response.status_code)


# Close the web driver
driver.quit()

As you can see from the image below, we get all the links of the images (data) provided on the given link (webpage).

Selenium Wire APIs

Selenium Wire provides a set of APIs that allow you to interact with and manipulate network traffic during test execution. These APIs enable you to capture, examine, and modify various aspects of HTTP requests and responses.

The following are some examples of APIs provided by Selenium Wire.

APIs	Description
request.headers:	It allows you to access the headers of the captured HTTP request.
response.headers:	It allows you to access the headers of the captured HTTP response.

workbook.save(output_path)
print(f"Video files listed in '{output_path}' successfully!")

Exploring Advanced Automation Techniques

Advanced automation techniques consist of advanced approaches and technologies used to enhance the capabilities and efficiency of automation scripts. Let us explore some of the advanced automation techniques.

Robotic Process Automation (RPA)

It involves the use of software robots or “bots” to automate repetitive, rule-based tasks that humans mainly perform. RPA bots interact with applications and systems through the user interface and reduce human actions to perform tasks such as data entry, form filling, report generation, etc.

Machine Learning and Artificial Intelligence (AI)

This helps the automation scripts to learn and adapt based on past patterns, data, and feedback. Artificial Intelligence (AI) is widely utilized across various domains, including natural language processing, image recognition, and bolstering the intelligence of automation scripts.

Automated Software Testing

Automated software testing plays a crucial role in evaluating the software’s quality, functionality, and performance. It is one of the most important phases of the Software Development Life Cycle (SDLC).

LambdaTest also supports various frameworks like Selenium, Cypress, etc for automated software testing and has played a key role in cross browser testing.

Cloud Automation

Cloud-based automation provides scalability and flexibility by executing automation scripts and managing resources on cloud platforms. It plays an important role in dynamic scaling and cost optimization since automation scripts can use cloud services and APIs for tasks such as data storage and processing. LambdaTest allows users to execute cloud-based automation testing using Selenium, Cypress, etc that results in faster delivery of high-quality software.

Web Scraping

Web scraping is the process of extracting data and content from other websites, and in this automation scripts play an important role because automation scripts can gather information from multiple web pages and aggregate data for analysis into the other systems.

Web scraping saves time and eliminates manual effort by automating the process of data retrieval from websites, consequently making automation scripts more efficient and powerful.

API Integration

API integration allows automation scripts to interact with external systems, services, or databases, expanding their reach and functionality. Through API integration, automation scripts can exchange data with popular platforms and access real-time information. This technique enables the automation of tasks like retrieving data from a CRM system, posting updates to social media platforms, or fetching data from cloud storage.

Selenium WebDriverWait: Implementing The Explicit Wait Command

UpendraPrasadMahto — Mon, 21 Aug 2023 09:31:11 +0000

In the dynamic realm of automation testing, achieving flawless execution and dependable results is of utmost importance. As web applications grow more intricate and user-centric, conventional test scripts may struggle to handle asynchronous behavior and varying loading times. This is where Selenium WebDriverWait emerges as a game-changer.

WebDriverWait, a potent feature of Selenium, the industry-standard web application testing tool, empowers testers to apply intelligent delays or “waits” in their scripts. These waits ensure that interactions with web elements occur precisely when they are ready, rather than being forced prematurely. In this blog, we will delve into the significance of Wait commands in automation testing and explore how Selenium’s WebDriverWait elevates the efficiency and accuracy of test suites. By addressing the challenges posed by asynchronous web applications, network latencies, cross-browser inconsistencies, and UI rendering, WebDriverWait not only enhances test stability and reliability but also improves overall test performance.

In this blog, we will briefly look at the concept of the Explicit Wait command in Selenium. Subsequently, we will look at Selenium WebDriverWait, a Java class that implements the Explicit Wait command.

We will discuss the benefits of Selenium WebDriverWait in automation testing. We’ll also explore ExpectedConditions in Selenium, covering its types and commonly used expected conditions. We’ll provide an illustrative example to demonstrate the implementation of Selenium WebDriverWait. This comprehensive approach will equip you with a strong foundation in working with one of the Wait Commands in Selenium.

What is Selenim WebDriverWait?

Selenium WebDriver offers different types of Wait Commands to handle synchronization in test automation. The concept of Selenium Wait revolves around pausing the execution of the script until certain conditions are met, ensuring that the test proceeds only when the desired state or element is available.

There are three types of Wait Commands:

Implicit Wait Command
Explicit Wait Command
Fluent Wait Command

“WebDriverWait” is a class in Java provided by the Selenium framework that allows you to implement the concept of Explicit Waits in your test automation scripts. It allows you to define custom wait conditions and specify the maximum duration for the WebDriver to wait until the condition is satisfied. It provides control and flexibility compared to Implicit Waits, which are based on a fixed waiting time.

Selenium WebDriverWait class allows defining expected conditions using built-in methods provided by the ExpectedConditions class, such as element visibility, element clickability, text presence, and many more.

You may check out our blog on Selenium Wait to learn in-depth about the Selenium Wait commands.

Test your native, hybrid, and web apps across all legacy and latest mobile operating systems on the most powerful online Android emulator.

Benefits of Using WebDriverWait

The implementation of the Explicit Wait command using the Selenium WebDriverWait class offers various benefits as listed below:

Selenium WebDriverWait allows your test scripts to wait for specific conditions to be met before proceeding, ensuring that the elements are ready for interaction. This reduces the chances of encountering errors or failures due to time-related issues.
Selenium WebDriverWait is particularly useful for handling dynamic web pages where elements may appear or change asynchronously. It enables you to wait for elements to be visible, clickable, or present before interacting with them, accommodating the dynamic nature of web applications.
Selenium WebDriverWait offers the flexibility to define custom wait conditions tailored to your specific testing requirements. You can create conditions based on JavaScript, CSS, or other relevant techniques, allowing you to handle unique scenarios not covered by built-in expected conditions.

Getting Started with Explicit Wait using Selenium WebDriverWait Class in Java

The Explicit Wait is a more intelligent approach than the Implicit Wait to handle synchronization in automation testing. Unlike Implicit, Explicit Wait allows you to pause the program execution for specific elements until they meet the desired conditions. It also provides more control and flexibility and is especially useful for waiting on dynamically loaded Ajax elements.

To use Explicit Wait, you must utilize the ExpectedConditions provided by Selenium.

Let’s discuss the ExpectedConditions in Selenium Webdriver.

ExpectedCondition in Selenium Webdriver

In automation testing, ensuring that the rendering of the web page and your instructions are in sync before proceeding is essential. Therefore, Selenium WebDriver provided ExpectedConditions that are used for performing Explicit Waits on a certain condition. These conditions are accessible in various programming languages and provide a user-friendly approach to waiting for specific conditions to be fulfilled. The availability of these conditions may differ based on the Selenium language bindings used.

Types of ExpectedConditions in Selenium Java

There are generally four categories of Expected Conditions in Selenium Java,

ExpectedCondition< WebElement >
ExpectedCondition< WebDriver >
ExpectedCondition< Boolean >
ExpectedCondition< Alert >

We will not look at each of these Expected Conditions one by one in detail.

ExpectedCondition < WebElement >

This ExpectedCondtions uses the WebElement as a parameter. Then the Explicit Wait is performed until the specified expected condition is fulfilled or the specified wait duration is reached. When the expected condition is fulfilled, it returns the corresponding WebElement, a list of WebElements, or other relevant information based on the core implementation of the ExpectedCondition.

ExpectedCondition < WebDriver >

This allows you to wait for WebDriver-related conditions to be satisfied before moving forward with your test execution. Once the specified operations are successfully performed, the method returns the WebDriver instance, indicating that the desired conditions have been met.

ExpectedCondition < Boolean >

This represents a condition that returns a Boolean value. It is used in Explicit Waits to wait for specific conditions to be satisfied and to return a Boolean value as a result indicating whether the condition has been met or not.

ExpectedCondition < Alert >

This represents a condition to wait for the presence of an alert on a web page. This type of condition is used in Explicit Waits to wait for an alert to be present. Once the alert is present, you can interact with it using methods like accept() to accept the alert or dismiss() to dismiss it.

We have discussed the different categories of ExpectedConditions in Selenium Java. Now, Let’s explore some of the commonly used ExpectedConditions in Selenium Java to implement Explicit Waits.

Commonly used ExpectedConditions in Selenium Java

In this section, we are going to look at the static methods provided in the ExpectedConditions class in Java. We will see how to use them in a practical way by writing Selenium Test Scripts.

elementToBeClickable Method

It is a method of ExpectedCondition that waits for an element to be clickable. This is especially useful in scenarios where elements may take some time to load, become enabled, or change state based on certain conditions.

Method Category — ExpectedCondition< WebElement >

Syntax –

ExpectedCondition<WebElement> elementToBeClickable(By locator)

presenceOfElementLocated Method

This method is used to wait for the presence of a specific element on a web page. It checks whether the element is available in the DOM (Document Object Model) of the page or not. If the element is found, the method returns the WebElement, indicating that the element is now ready for further interactions in your automation testing. In other words, it ensures that the element is loaded and can be accessed before proceeding with any actions on it.

Method Category — ExpectedCondition< WebElement >

Syntax-

ExpectedCondition<WebElement> presenceOfElementLocated(By locator)

visibilityOfElementLocated Method

This method waits for an element to be both present in the DOM and visible on the web page before proceeding with the test execution. Similar to the presenceOfElementLocated Method, this also checks if the element is present in the DOM of the page. But this method does one thing extra as this checks if the element also has a non-zero size, meaning it is visible to the user on the web page or not. If the element meets both conditions, the method returns the WebElement, indicating that the element is now visible and is available for further interactions.

Method Category — ExpectedCondition< WebElement >

Syntax-

ExpectedCondition<WebElement> visibilityOfElementLocated(By locator)

visibilityOfAllElementsLocatedBy Method

This method is similar to the visibilityOfElementLocated Method. The only difference is that it waits for all elements matching a specific locator to be both present in the DOM and visible on the web page before proceeding with the test execution.

Method Category — ExpectedCondition< WebElement >

Syntax-

ExpectedCondition<WebElement> visibilityOfAllElementsLocatedBy(By locator)

Let’s take an example to understand the above method.

(We will implement various tests using the LambdaTest’s Demo Website)

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import java.time.Duration;
import java.util.List;

public class SeleniumWebDriverWaitExample {

  public static void main(String[] args) {
  WebDriver driver = new ChromeDriver();
  // Navigate to the website
  driver.get("https://www.lambdatest.com/automation-demos");
  // Initialize WebDriverWait with a timeout of 5 seconds
  WebDriverWait wait =new WebDriverWait(driver, Duration.ofSeconds(5));
  // ExpectedCondition for Presence of Element Located
  WebElement elementLocated = wait.until(ExpectedConditions.presenceOfElementLocated(By.id("username")));
  elementLocated.sendKeys("xyz@lambdatest");
  driver.findElement(By.id("password")).sendKeys("LambdaTest");
  // ExpectedCondition for Element to be Clickable
  WebElement clickableElement = wait.until(ExpectedConditions.elementToBeClickable(By.linkText("Blogs")));
  clickableElement.click();
  // ExpectedCondition for Visibility of Element Located
  WebElement visibleElement = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id=\"menu-item-35\"]/a")));
  String elementText = visibleElement.getText();
  System.out.println(elementText);

  // ExpectedCondition for Visibility of All Elements Located
  List<WebElement> allVisibleElements = wait.until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.xpath("//*[@id=\"site-navigation\"]/div")));
  for (WebElement element : allVisibleElements) {
  System.out.println(element.getText());
  }
  // Close the browser
  driver.quit();
  }
}

In the above program, we started by importing the necessary modules and then created a WebDriver instance(e.g. ChromeDriver in our case) to navigate to our desired website.

Now, let’s look at the different ExpectedConditions methods used in the program above program.

presenceOfElementLocated: We waited for an element with the ID attribute “username” to be present in the DOM of the webpage. Once the element was found, it returned a reference to the WebElement, and we used the sendKeys method to input the text “xyz@lambdatest” into the corresponding input field. Similarly, we found the element with the ID attribute “password” and entered the text “LambdaTest” into the input field.

A comprehensive end-to-end Testing tutorial that covers what E2E Testing is, its importance, benefits, and how to perform it with real-time examples:.

elementToBeClickable: This method waited for the element with the link text “Blogs” to become clickable. Once the element was clickable, it returned a reference to the WebElement, and we utilized the click method to navigate to the “Blogs” section.

visibilityOfElementLocated: We waited for an element with the specified XPath expression to become visible on the webpage. Once it became visible, the method returned the WebElement reference, and we extracted the text of the element and printed it.

visibilityOfAllElementsLocatedBy: In this case, we waited for all elements matching the given XPath expression to be visible on the webpage. Once all elements were visible, the method returned a list of WebElement references. We then iterated through the list and printed the text of each element.

frameToBeAvailableAndSwitchToIt Method

This method is used to wait for a frame to be available on a web page and then switch the driver’s focus to that frame.

Method Category — ExpectedCondition< WebDriver >

Syntax-

ExpectedCondition<WebDriver> frameToBeAvailableAndSwitchToIt(By locator)

elementToBeSelected Method

This method is used to wait until the WebElement is selected with a specified locator. It is handy when you deal with web pages that involve user interactions, such as selecting options from dropdown menus, clicking checkboxes, or choosing radio buttons.

Method Category — ExpectedCondition< Boolean >

Syntax-

ExpectedCondition<Boolean> elementToBeSelected(By locator)

invisibilityOfElementLocated Method

This method is used to wait for a web element to become invisible or hidden on the web page before proceeding further. It continuously checks if the element is present in the DOM and visible on the page. If the element becomes invisible, it returns ‘true’, indicating that the element is no longer visible.

Method Category — ExpectedCondition< Boolean >

Syntax-

ExpectedCondition<Boolean> invisibilityOfElementLocated(By locator)

textToBe Method

This method is used to wait for the text of a web element to be equal to a given string (passes as a parameter) before proceeding further.

Method Category — ExpectedCondition

Syntax-

ExpectedCondition<Boolean> textToBe(By locator, String text)

Let’s understand textToBe method with an example.

public class SeleniumWebDriverWaitExample {

 public static void main(String[] args) {
  WebDriver driver = new ChromeDriver();
  // Navigate to the website
  driver.get("https://www.lambdatest.com/automation-demos");
  // Initialize WebDriverWait with a timeout of 5 seconds
  WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(5));
  try {
  wait.until(ExpectedConditions.textToBe(By.xpath("//*[@id=\"newapply\"]/h2"), "Login Selenium Playground"));
  } catch (TimeoutException e) {
  // Handle the TimeoutException
  } finally {
  // Close the browser
  driver.quit();
  }
 }
}

In the above program, we use the Explicit Wait concept with Selenium WebDriverWait and ExpectedConditions textToBe method to wait for a specific element on the webpage to contain the given text “Login Selenium Playground”. Since the given text does not match the text located using the XPath expression in the specified time. Therefore a TimeoutException is caught, and the WebDriver is correctly closed after waiting for 5 seconds.

Now. we pass “Login to Selenium Playground” as a given text. In this case, the given text matches with the text located using the XPath expression. Therefore the WebDriver properly closed before 5 seconds.

public class SeleniumWebDriverWaitExample {

 public static void main(String[] args) {
  WebDriver driver = new ChromeDriver();
  // Navigate to the website
  driver.get("https://www.lambdatest.com/automation-demos");
  // Initialize WebDriverWait with a timeout of 5 seconds
  WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(5));
  try {
  wait.until(ExpectedConditions.textToBe(By.xpath("//*[@id=\"newapply\"]/h2"), "Login to Selenium Playground"));
  } catch (TimeoutException e) {
  // Handle the TimeoutException
  } finally {
  // Close the browser
  driver.quit();
  }
 }
}

textToBePresentInElementLocated Method

This method is used to check whether a given text (passed as a parameter to the method) is present in the visible text of a web element or not.

If the given text is present in the web element, it returns a boolean value ‘true’ or otherwise returns ‘false’.

Method Category — ExpectedCondition< Boolean >

Syntax-

ExpectedCondition<Boolean> textToBePresentInElementLocated(By locator, String text)

Let’s understand the textToBePresentInElementLocated method with an example.

public class SeleniumWebDriverWaitExample {

 public static void main(String[] args) {
  WebDriver driver = new ChromeDriver();
  // Navigate to the website
  driver.get("https://www.lambdatest.com/automation-demos");
  // Initialize WebDriverWait with a timeout of 5 seconds
  WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(5));
  // Wait for the element to contain the expected text
  wait.until(ExpectedConditions.textToBePresentInElementLocated(By.xpath("//*[@id=\"newapply\"]/h2"), "Selenium"));
  // Close the browser
  driver.quit();
 }
}

In this case, the given text “Selenium” matches with the text located using the XPath expression. Therefore the WebDriver properly closed before 5 seconds.

textToBePresentInElementValue Method

This method is used to check whether a given text (passed as a parameter to the method) is present in the specified elements value attribute or not.

If the given text is present, it returns a boolean value ‘true’ or otherwise returns ‘false’.

Method Category — ExpectedCondition< Boolean >

Syntax-

ExpectedCondition<Boolean> textToBePresentInElementValue(By locator, String text)

titleContains Method

This method is used to check whether a given title/text is present in the current page title or the title of a WebElement or not.

If the given text is present in the current page title, it returns a boolean value ‘true’ or otherwise returns ’false’.

Method Category — ExpectedCondition< Boolean >

Syntax-

ExpectedCondition<Boolean> titleContains(String title)

Let’s understand the titleContains method with an example.

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import java.time.Duration;

public class SeleniumWebDriverWaitExample {

 public static void main(String[] args) {
  WebDriver driver = new ChromeDriver();
  // Navigate to the website
  driver.get("https://www.lambdatest.com/automation-demos");
  // Initialize WebDriverWait with a timeout of 5 seconds
  WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(5));
  boolean isTitleContains = false;
  try {
  wait.until(ExpectedConditions.titleContains("Selenium Playground"));
  isTitleContains = true;
  } catch (org.openqa.selenium.TimeoutException e) {
  isTitleContains = false;
  }
  // Print the result
  System.out.println("Is title contains 'Selenium Playground'? " + isTitleContains);
  // Close the browser
  driver.quit();
 }
}

Output:

Is title contains 'Selenium Playground'? true

In this case, the given title “Selenium Playground” matches the title of the webpage. Therefore it returns true and the result is printed. (As you can see in the Output)

titleIs Method

This method is used to check whether a web page title is exactly match with the given string(passed as a parameter) or not.

If the given text matches with the title of the webpage then it returns a boolean value ‘true’ or otherwise ‘false’.

Method Category — ExpectedCondition< Boolean >

Syntax-

ExpectedCondition<Boolean> titleIs(String title)

urlContains Method

This method is used to check whether a URL of a webpage contain a specific string or given string (passed as a parameter) or not.

If the given string is present in the URL then it returns a boolean value ‘true’ or otherwise ‘false’.

Method Category — ExpectedCondition< Boolean >

Syntax-

ExpectedCondition<Boolean> urlContains(String fraction)

Let’s understand the urlContains method with an example.

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import java.time.Duration;
public class SeleniumWebDriverWaitExample {
 public static void main(String[] args) {
  WebDriver driver = new ChromeDriver();
  // Navigate to the website
  driver.get("https://www.lambdatest.com/automation-demos");
  // Initialize WebDriverWait with a timeout of 5 seconds
  WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(5));
  boolean isurlContains = false;
  try {
  wait.until(ExpectedConditions.urlContains("automation-demos"));
  isurlContains = true;
  } catch (org.openqa.selenium.TimeoutException e) {
  isurlContains = false;
  }
  // Print the result
  System.out.println("Is url contains 'automation-demos'? " + isurlContains);
  // Close the browser
  driver.quit();
 }
}

Output:

Is url contains 'automation-demos'? true

In this case, the URL of the webpage contains automation-demos. Therefore it returns true and the result is printed. (As you can see in the Output)

Now, we passed the “xyz” and since the URL of the webpage didn’t contain “xyz”. Therefore it returns false and the result is printed. (As you can see in the Output)

public class SeleniumWebDriverWaitExample {

 public static void main(String[] args) {
  WebDriver driver = new ChromeDriver();
  // Navigate to the website
  driver.get("https://www.lambdatest.com/automation-demos");
  // Initialize WebDriverWait with a timeout of 5 seconds
  WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(5));
  boolean isurlContains = false;
  try {
  wait.until(ExpectedConditions.urlContains("xyz"));
  isurlContains = true;
  } catch (org.openqa.selenium.TimeoutException e) {
  isurlContains = false;
  }
  // Print the result
  System.out.println("Is url contains 'xyz'? " + isurlContains);
  // Close the browser
  driver.quit();
 }
}

Output:

Is url contains 'xyz'? false

urlToBe Method

This method is used to check whether the URL of a web page exactly matches a specific URL/given URL or not.

If the given string exactly matches the URL of the webpage, it returns a boolean value ‘true’ or otherwise returns ‘false’.

Method Category — ExpectedCondition< Boolean >

Syntax-

ExpectedCondition<Boolean> urlToBe(String url)

alertIsPresent Method

This method is used to wait for an alert dialog to be present on a web page and then perform actions like accepting or dismissing the alert as part of your test flow. This method is particularly useful when dealing with web pages that use JavaScript-based alert boxes to show messages, prompts, or confirmations to the user.

Method Category — ExpectedCondition< Alert >

Syntax-

ExpectedCondition<Alert> alertIsPresent()

Let’s take an example for better understanding.

import org.openqa.selenium.Alert;

import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import java.time.Duration;

public class SeleniumWebDriverWaitExample {

 public static void main(String[] args) {
  WebDriver driver = new ChromeDriver();
  // Navigate to the website
  driver.get("https://www.lambdatest.com/selenium-playground/javascript-alert-box-demo");
  driver.findElement(By.xpath("//*[@id=\"__next\"]/section[3]/div/div/div/div[1]/p/button")).click();
  // Initialize WebDriverWait with a timeout of 5 seconds
  WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(5));
  // Wait until an alert is present
  boolean isAlertPresent = false;
  try {
  wait.until(ExpectedConditions.alertIsPresent());
  isAlertPresent = true;
  } catch (org.openqa.selenium.TimeoutException e) {
  isAlertPresent = false;
  }
  // Print the result
  System.out.println("Is alert present? " + isAlertPresent);
  // If alert is present, handle it
  if (isAlertPresent) {
  Alert alert = driver.switchTo().alert();
  String alertText = alert.getText();
  System.out.println("Alert Text: " + alertText);
  // Accept the alert (Click OK)
  alert.accept();
  }
  // Close the browser
  driver.quit();
 }
}

Output:

Is alert present? true
Alert Text: Alert box!

In the above program, we use the Explicit Wait concept with Selenium WebDriverWait to check if an alert is present on a web page. It waits for a maximum of 5 seconds for the alert to appear. The result is then printed to the console, indicating whether the alert is present or not.

If the alert is present, its text is retrieved and printed to the console. The alert is then accepted by clicking the “OK” button.

(As you can see in the image below)

Finally, the code closes the web browser, ensuring smooth execution of the test regardless of the presence of the alert.

Limitations of Selenium WebDriverWait

Selenium WebDriverWait is a class in Java used for handling synchronization automation testing. However, it does have some limitations. Let’s explore them.

Limited to Web-Based Applications: Selenium WebDriverWait is specifically designed for web-based applications and cannot be used for other types of applications. For example — Mobile.
Dependency on Web Elements: Selenium WebDriverWait relies on web elements to determine the synchronization condition. If the desired web element is not present or accessible, it can cause the wait to fail or result in a longer wait time.
Performance Impact: Using Selenium WebDriverWait excessively or with long wait times can impact the performance of test execution. Therefore, it is important to find the right balance between wait times and test execution speed.
Difficulties with Dynamic Elements: While Selenium WebDriverWait can handle some dynamic elements, it may encounter challenges with highly dynamic web pages where elements frequently change or are added/removed dynamically.
Lack of Native Support for Asynchronous Operations: Selenium WebDriverWait may not handle all types of asynchronous operations or AJAX requests by default. Additional customization may be required to handle such scenarios.

Conclusion

Learn to Handle Mouse Hover in Selenium

UpendraPrasadMahto — Fri, 18 Aug 2023 09:15:32 +0000

Mouse hover actions play a vital role in web automation testing, especially when dealing with interactive user interfaces. During web automation, you may encounter a situation where certain features or elements on the user interface only appear or respond when the user hovers the mouse over them. The hover effect is essential for providing interactive and dynamic website user experiences. You can hover over an element using the Actions Class of Selenium WebDriver API and its method. By doing so, you can automate the validation of hover-based functionalities and ensure that the web application behaves correctly when users interact with it.

In this article, we will explore the concept of mouse hover in Selenium and then discuss its importance in automation testing. After that, we will delve into the technical aspects of how to implement it using Selenium WebDriver followed by some best practices. We will use Python programming language to implement Mouse hover in Selenium.

Perform browser testing on the most powerful automation testing platform. Leverage LambdaTest automation testing for faster, reliable and scalable experience on cloud.

What is Mouse Hover in Selenium?

Mouse hover in Selenium means using Selenium WebDriver to simulate a mouse hover action on an element. This action triggers various UI effects, such as displaying tooltips, revealing hidden elements, or opening drop-down menus. Mouse hover in Selenium is important in automated testing as they help validate dynamic behaviors and hidden functionalities that may only become visible or accessible upon hovering over certain elements. By performing mouse hover actions in automation tests, testers can ensure the accuracy and reliability of web applications under test.

As you may see from the image attached below, the home page of Flipkart (as it looks while writing this blog), Electronics is one of the broad categories listed on this e-commerce website. It is only when you hover over this category or element it displays or renders the sub-category list on the DOM. Further, when you hover over the Gaming sub-category, it displays or renders the following list of items on the DOM.

This kind of use case is part of a UI that interacts well with the user.

Importance of Mouse Hover in Selenium

Mouse hover in Selenium is highly valuable for various scenarios in automation testing, as listed below:

It allows testers to ensure that dropdown menus work properly when the mouse hovers over them and that all menu options are functional.
Testers can also verify tooltips and information that appear when hovering over certain elements.
Mouse hover in Selenium enables the validation of hidden or dynamic elements, making sure they become visible and interactive when the mouse hovers over specific areas.

How to Perform Mouse Hover in Selenium?

To perform mouse hover in Selenium, we use the Actions Class from the Selenium WebDriver API. This Class provides various methods to simulate complex user interactions. By creating an instance of the Actions Class and using its method, you can move the mouse pointer to the desired element on the web page and trigger the hover effect.

Once the hover action is performed, you can further validate the web application’s behavior using assertions or other validation techniques. It ensures that the mouse hover interactions work as intended.

So, let’s first explore the Actions Class of Selenium WebDriver before we get into the practical example of implementing mouse hover in Selenium.

In this article, let us learn about the test cases for banking Applications that are used to test a banking application. Before that, let us understand the workings of the banking domain in brief.

Actions Class of Selenium WebDriver

The Actions Class in Selenium is part of the Selenium WebDriver API and can be found in the selenium.webdriver.common.action_chains module. This class offers a range of methods that enable the simulation of complex user interactions, including Mouse Hover Action, Clicking, Double-clicking, Dragging, Releasing, Holding an element, and many more.

You don’t need to install any additional libraries or packages to use the Actions Class in Selenium. The Actions Class is bundled in the Selenium WebDriver API and comes pre-installed with Selenium binding.

You may consider watching the below video from our Youtube channel to learn in detail how to handle Actions class in Selenium.

Follow the below steps to use the Actions Class:

Import the webdriver module from the Selenium package.
Import the ActionChains Class from the selenium.webdriver.common.action_chains module.

After importing, the code snippet looks like this.

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains

Implementing Mouse Hover in Selenium

Let’s take an example to understand mouse hover in Selenium using the Actions Class.

We are going to use automation demos, a demo website maintained by LambdaTest for illustrations.

To implement Mouse Hover in Selenium, we will use the Actions Class of Selenium WebDriver API.

In the following example, we demonstrate how to use Selenium to perform a hover action over the “Resources” element and wait for up to 5 seconds and quit the browser session:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
import time

# Launch the Chrome browser
driver = webdriver.Chrome()

# Navigate to the website
driver.get("https://www.lambdatest.com/automation-demos")
driver.maximize_window()

# Locate the element to perform the hover action on
element_to_hover = driver.find_element(By.XPATH, '//*[@id="header"]/nav/div/div/div[2]/div/div/div[1]/div[3]/button')

# Create an instance of the ActionChains class
actions = ActionChains(driver)

# Perform the hover action
actions.move_to_element(element_to_hover).perform()
time.sleep(5)

# Close the browser
driver.quit()

As shown in the above example, we perform a mouse hover action over the “Resources” element and wait for 5 seconds and quit the browser.

Let’s take another example where we automate the mouse hover action over an element and perform the click() action.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
import time

# Launch the Chrome browser
driver = webdriver.Chrome()

# Navigate to the website
driver.get("https://www.lambdatest.com/automation-demos")
driver.maximize_window()

# Locate the element to perform the hover action on
element_to_hover = driver.find_element(By.XPATH, '//*[@id="header"]/nav/div/div/div[2]/div/div/div[1]/div[3]/button')

element_to_hover1=driver.find_element(By.XPATH, '//*[@id="header"]/nav/div/div/div[2]/div/div/div[1]/div[3]/div/div/div/div[1]/div/div[1]/ul/li[3]/a/div[2]/h3')
# Create an instance of the ActionChains class
actions = ActionChains(driver)

# Perform the hover action
actions.move_to_element(element_to_hover).perform()
time.sleep(5)
actions.move_to_element(element_to_hover1).perform()
time.sleep(5)
actions.click(element_to_hover1).perform()
time.sleep(5)

# Close the browser
driver.quit()

As shown in the above example, we first hover over the Resources using their XPath and wait for 5 seconds, then we hover over Learning Hub and again wait for 5 seconds. After that, we perform the click() action on Learning Hub and again wait for 5 seconds.

We have used the Actions Class from the Selenium WebDriver API. Now, let’s delve deeper into our comprehension by exploring the various methods and properties offered by the Actions Class in detail.

Methods and Properties of Actions Class in Selenium

The Actions Class in Selenium has various methods and properties, which we will look at in this section with code examples.

move_to_element(WebElement element)

Moves the mouse cursor to the center of the specified web element.

Syntax:

actions.move_to_element(element)

Let’s understand this through an example.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
import time

# Launch the Chrome browser
driver = webdriver.Chrome()

# Navigate to the website
driver.get("https://www.lambdatest.com/automation-demos")
driver.maximize_window()
time.sleep(3)

# Locate the element to perform the hover action on
main_element = driver.find_element(By.XPATH, '//*[@id="header"]/nav/div/div/div[2]/div/div/div[1]/div[1]/div[1]/a')
sub_element = driver.find_element(By.XPATH, '//*[@id="header"]/nav/div/div/div[2]/div/div/div[1]/div[1]/div[2]/div[1]/div/div[1]/div/div[1]/ul/li[2]/a/div[2]/p')
# Create an instance of the ActionChains class
actions = ActionChains(driver)

# Build the mouse hover action with multiple actions using build()
actions = actions.move_to_element(main_element)
actions = actions.move_to_element(sub_element)

# Perform the built actions using perform()
actions.perform()

# Wait for a few seconds to observe any effects
time.sleep(5)

# Close the browser
driver.quit()

In the above example, we have used the move_to_element() method. Firstly, we hover over the Platform and then move to Selenium Testing, as shown below.

click(WebElement element):

Clicks the specified web element.

Syntax:

actions.click(element)

Let’s understand this through an example.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
import time

# Launch the Chrome browser
driver = webdriver.Chrome()

# Navigate to the website
driver.get("https://www.lambdatest.com/automation-demos")
driver.maximize_window()
time.sleep(3)

# Locate the element to perform the hover action on
main_element = driver.find_element(By.XPATH, '//*[@id="header"]/nav/div/div/div[2]/div/div/div[2]/a[2]')

# Create an instance of the ActionChains class
actions = ActionChains(driver)

# Build the mouse hover action with multiple actions using build()
actions = actions.click(main_element)

# Perform the built actions using perform()
actions.perform()

# Wait for a few seconds to observe any effects
time.sleep(5)

# Close the browser
driver.quit()

In the above example, we used the click() method where we first hover over the element Sign Up and then perform a click() action on it.

click_and_hold(WebElement element)

Clicks and holds the specified web element. This function also needs the release() method to get the desired functionality.

Syntax:

actions.click_and_hold(element)

release(WebElement element)

Releases the mouse button previously held on the specified web element.

Syntax:

actions.release(element)

Let’s take an example where we want to hover over an element (Book a Demo) and want to use click_and_hold() and release() methods.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
import time

# Launch the Chrome browser
driver = webdriver.Chrome()

# Navigate to the website
driver.get("https://www.lambdatest.com/automation-demos")
driver.maximize_window()

# Locate the "Resources" menu option to perform the hover action
Book_a_Demo = driver.find_element(By.XPATH, '//*[@id="header"]/nav/div/div/div[2]/div/div/div[2]/div[1]/button')

# Create an instance of the ActionChains class
actions = ActionChains(driver)
time.sleep(3)

# Perform the mouse hover action on the "Resources" menu option
actions.move_to_element(Book_a_Demo).perform()

# Click and hold the "Resources" menu option for 3 seconds
actions.click_and_hold().perform()
time.sleep(3)

# Release the click
actions.release().perform()

# Wait for a few seconds to observe any effects
time.sleep(5)

# Close the browser
driver.quit()

In the above example, we have performed a mouse hover over the “Book a Demo” element after 3 seconds of opening the page and used the click_and_hold() on the element for 3 seconds. Subsequently, we release the element using the release() method, maintaining the release for 5 seconds. This sequence of actions simulates user interaction and allows us to observe the effects on the “Book a Demo” element during the specified timeframes.

(You can see as we hover over the element “Book A Demo”, the border gets thicker.)

double_click(WebElement element)

Performs a double-click action on the specified web element.

Syntax:

actions.double_click(element)

Let’s understand this through an example.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
import time

# Launch the Chrome browser
driver = webdriver.Chrome()

# Navigate to the website
driver.get("https://www.lambdatest.com/selenium-playground/")
driver.maximize_window()
time.sleep(3)

# Locate the element to perform the hover action on
main_element = driver.find_element(By.XPATH, '//*[@id="__next"]/div/section[1]/div/h1')

# Create an instance of the ActionChains class
actions = ActionChains(driver)

# Build the mouse hover action with multiple actions using build()
actions = actions.double_click(main_element)

# Perform the built actions using perform()
actions.perform()

# Wait for a few seconds to observe any effects
time.sleep(5)

# Close the browser
driver.quit()

In the above example, we used the double_click() method where we perform a double-click on the text ‘Playground’, as you can see below.

Run your Selenium online Automation Testing scripts on the LambdaTest cloud grid. Test on 3000+ desktop & mobile environments. Try it for free.

context_click(WebElement element)

Performs a right-click (context-click) action on the specified web element.

Syntax:

actions.context_click(element)

Let’s take an example to understand the context_click() method.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
import time

# Launch the Chrome browser
driver = webdriver.Chrome()

# Navigate to the website
driver.get("https://www.lambdatest.com/automation-demos")
driver.maximize_window()

# Locate the "Resources" menu option to perform the hover action
context = driver.find_element(By.XPATH, '//*[@id="formcontent"]')

# Create an instance of the ActionChains class
actions = ActionChains(driver)
time.sleep(3)

# Perform the double click on the "Resources" menu option
actions.context_click(context).perform()

# Wait for a few seconds to observe any effects
time.sleep(5)

# Close the browser
driver.quit()

In the above program, we have performed the context_click() method. This method is nothing, but it is just like a right-click. We automate the process of right-clicking through the Actions Class, as you can show in this example.

drag_and_drop(WebElement source, WebElement target)

Drags the source element and drops it onto the target element.

Syntax:

actions.drag_and_drop(source, target)

Let’s take an example to understand the drag_and_drop() method.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
import time

driver = webdriver.Chrome()
driver.get("https://jqueryui.com/droppable/")
driver.maximize_window()

driver.switch_to.frame(driver.find_element("class name", "demo-frame"))

# get the source and destination
source = driver.find_element(By.ID, "draggable")
destination = driver.find_element(By.ID, "droppable")

actions = ActionChains(driver)
time.sleep(2)

# drag_and_drop() method
actions.drag_and_drop(source, destination).perform()

# Wait for a few seconds to observe any effects
time.sleep(5)
driver.quit()

In the above program, we have performed the drag_and_drop() method. This method drags an element and drops it to the desired location. We automate the drag-and-drop process through the Actions Class, as shown in this example.

pause(long duration)

Pauses the execution for the specified duration in milliseconds.

Syntax:

actions.pause(duration)

Let’s take an example to understand the pause() method.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
import time

# Launch the Chrome browser
driver = webdriver.Chrome()

# Navigate to the website
driver.get("https://www.lambdatest.com/automation-demos")
driver.maximize_window()

# Locate the element to perform the hover action on
element = driver.find_element(By.XPATH, '//*[@id="footer"]/div[1]/div/div/div[2]/div/div[2]/ul/li[1]/a')

actions = ActionChains(driver)

# Perform the hover action
actions.move_to_element(element)

# Introduce a pause of 3 seconds
actions.pause(3)

# Click on the element after the pause
actions.click(element)

# Perform the built actions using perform()
actions.perform()

# Wait for a few seconds to observe any effects
time.sleep(5)

# Close the browser
driver.quit()

In this example, we first hover over the Blogs and pause for 3 seconds, then perform the click() action on it.

build()

Create complex actions or perform multiple actions sequentially.

Syntax:

actions.build()

Let’s take an example to understand the build() method.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
import time

# Launch the Chrome browser
driver = webdriver.Chrome()

# Navigate to the website
driver.get("https://www.lambdatest.com/automation-demos")
driver.maximize_window()
time.sleep(3)

# Locate the element to perform the hover action on
main_element = driver.find_element(By.XPATH, '//*[@id="header"]/nav/div/div/div[2]/div/div/div[1]/div[3]/button')
sub_element = driver.find_element(By.XPATH, '//*[@id="header"]/nav/div/div/div[2]/div/div/div[1]/div[3]/div/div/div/div[1]/div/div[1]/ul/li[1]/a/div[2]/p')

# Create an instance of the ActionChains class
actions = ActionChains(driver)

# Build the mouse hover action with multiple actions using build()
hover_action = actions.move_to_element(main_element).move_to_element(sub_element).click(sub_element)

# Perform the built actions using perform()
hover_action.perform()

# Wait for a few seconds to observe any effects
time.sleep(5)

# Close the browser
driver.quit()

In the above example, we have used the build() method, which allows us to create a sequence of multiple actions more organized and concisely. This technique helps to perform complex interactions by chaining actions together. As shown in this example, we sequentially execute actions like move_to_element() and click() using the build() method.

First, we hover over the Resources. Then we hover over Blog using the move_to_element() method. At last, we performed the click() action. All the actions are performed sequentially

perform():

Executes the sequence of actions defined using the Actions Class.

Syntax:

actions.perform()

Best Practices for Mouse Hover Actions in Selenium

It is essential to follow some best practices while performing mouse hover actions in Selenium to ensure reliable and effective test automation. The following are some best practices for mouse hover actions in Selenium.

Use the Actions Class: The Actions Class in Selenium provides a high-level interface for performing mouse and keyboard actions. It offers methods like move_to_element(), click_and_hold(), etc, that are specifically designed for mouse actions. You may use this class to perform mouse hover actions effectively.
Locate Elements Accurately: To accurately locate the elements, you must use reliable and unique locators such as ID, Class, XPath, or CSS Selectors to identify the elements.
Use Explicit Waits: In some cases, elements may become visible only after a certain action or delay. You can handle such dynamic elements by using explicit waits (WebDriverWait) and waiting for the element to be visible or clickable before performing the hover action.

For Example-

import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains

driver = webdriver.Chrome()
driver.get("https://www.lambdatest.com/automation-demos")
driver.maximize_window()

wait = WebDriverWait(driver, 10)
element = wait.until(EC.visibility_of_element_located((By.XPATH, '//*[@id="__next"]/div[1]/section[1]/div')))
element1 = driver.find_element(By.XPATH, '//*[@id="header"]/nav/div/div/div[2]/div/div/div[1]/div[1]/div[1]/a')  
actions = ActionChains(driver)
actions.move_to_element(element1).perform()
time.sleep(5)

driver.quit()

In this example, we use Selenium WebDriver to perform a mouse hover in Selenium by using explicit waits. After opening the website, we locate the element (Selenium Playground) using its XPath and wait for it for 10 seconds to become visible. Then, we find another element (Platform) to perform the hover action on it. After the hover action, we wait for 5 seconds to observe any effects.

This approach is particularly beneficial when dealing with dynamic elements that may take some time to load.

Validate the Hover Effect: After performing the mouse hover action, verify that the expected changes or effects are reflected on the webpage. You can use assertions or other validation techniques to ensure the desired behavior.

Code Example:

import unittest
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
import time

class TestHoverEffect(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()
        self.driver.get("https://www.lambdatest.com/automation-demos")
        self.driver.maximize_window()

    def test_hover_effect(self):
        # Locate the element to perform the hover action on
        element_to_hover = self.driver.find_element(By.XPATH, '//*[@id="header"]/nav/div/div/div[2]/div/div/div[1]/div[3]/button')
        time.sleep(3)

        # Create an instance of the ActionChains class
        actions = ActionChains(self.driver)

        # Perform the hover action
        actions.move_to_element(element_to_hover).perform()

        # Wait for a few seconds to observe any effects
        time.sleep(3)

        # Validate the hover effect - Check if sub-menus becomes visible
        sub_menu = self.driver.find_element(By.XPATH, '//*[@id="header"]/nav/div/div/div[2]/div/div/div[1]/div[3]/div/div/div/div[1]/div/div[1]/ul')
        is_sub_menu_visible = sub_menu.is_displayed()

        # Print the result
        if is_sub_menu_visible:
            print("Sub-menu is visible after hover.")
        else:
            print("Sub-menu is not visible after hover.")


    def tearDown(self):
        self.driver.quit()

if __name__ == "__main__":
    unittest.main()

Output:

We started by importing all the necessary modules from Selenium, including unittest, webdriver, By, ActionChains, and time.

In the setUp method, we first created a WebDriver instance (ChromeDriver in our case) is created. The script then navigates to the automation-demos website and maximizes the browser window.

In the test_hover_effect method, the element to perform the hover action on is located using its XPath, and a 3-second pause is introduced to ensure that the page is fully loaded before performing the action. The after we created an instance of the Actions class as actions.

The move_to_element(element_to_hover) method is called on actions to perform the mouse hover action on the specified element.

Another 3-second pause is introduced to observe any effects of the hover action.

The sub-menu element is located using its XPath, and its visibility is checked using the is_displayed() method. Based on the visibility of the sub-menu, the script prints whether the sub-menu is visible or not after the hover action.

The tearDown method closes the browser and ends the test.

The program uses the Actions Class to perform the hover action, then checks if the sub-menu is displayed using the is_displayed() method. At last, we printed the result.

This helps validate the expected behavior of the hover effect on the dropdown menu during automation testing.
