Selenium Automation

#automation #opensource #testing #webdev

Selenium is one of the most popular tools used for automating web applications. Imagine you open a browser, type a website address, click buttons, fill forms and check whether everything works properly. Doing all this manually takes time and effort. Selenium helps us by performing these actions automatically, just like a human would, but much faster and more accurately.

Selenium Features:
1.Web-based Automated Testing
2.Multiple OS
3.Multiple Browsers
4.Multiple programming languages
5.Multiple frameworks
6.Open Source

Selenium Components:
1.Selenium IDE
2.Selenium RC
3.Selenium Web driver
4.Selenium Grid

Applications of Selenium:
1.Automated Web Application Testing
2.Cross-Browser Testing
3.Web Scraping
4.Continuous Integration/ Continuous Deployment
5.Functional Testing

Limitations of Selenium:
1.Slow Test Execution
2.Difficulty in handling Dynamic web elements
3.Cross-Browser Compatibility is less sometimes
4.Limited support for mobile applications
5.Limited support for windows-based applications

Why do we use Selenium for Automation ?

Selenium is a free open-source test execution automation platform for assessing web applications and Selenium implements itself using a browser-specific driver that accepts and transmits commands to the browser. Testers can evaluate the user experience and make sure the application is clear and easy to use by using selenium. The main component of the selenium automation tool is Selenium Web driver.
Selenium is widely used for automation testing, particularly for web applications, due to a combination of factors:
1.Open source and Cost-effective:

Cross-Browser and Cross-Platform Compatibilty
Multi-Language Support
Flexibilty and Extensibility
Parallel Test Execution
Reduced Manual Effort and Improved Efficiency

Advantages of Selenium in automation:
1.It is an open-source tool.
2.Provide base for extensions.
3.It provides multi-browser support.
4.The user can set breakpoints and debug.
5.Selenium is completely integrated with CI/CD -platforms like Jenkins, Azure DevOps, bamboo etc.

Disadvantages of selenium in automation:
1.Supports web applications only, it is unable to automate processes outside of the browser such as desktop applications.
2.Selenium does not have a basic functionality called reports, wherein to communicate with testers, developers etc. reports must be generated.
3.No technical support will be provided.
4.Lack of professional support can be quite difficult because it can be difficult to troubleshoot problems.

Relevance of Selenium in Automation Testing using Python:

Every tester aims to ensure that all software components are functional and user-friendly. This is why many teams turn to Selenium to conduct effective test automation.
