How a Bad Push Crashed the Cloud Systems Outage:From One Region to Worldwide

Ayushi Shrivastava — Tue, 28 Oct 2025 13:53:06 +0000

In a cloud environment, professionals plan and release updates to speed up processes and adopt best-in-class practices. Most of the time, it goes well, but once in a blue moon, a bad push turns into a disaster, bringing the systems to a halt.

On Monday, 20 October, AWS experienced a worldwide cloud outage that affected many apps, websites, and social media platforms. Initially, no one had expected it to turn into a global cloud outage, but soon users began reporting issues on Twitter.

Soon, it was confirmed that the single-point failure in the US-East region had reached a significant threshold.

Give this blog post a read to learn in depth about how to recover from a cloud outage, ensuring the app remains available.

How a Routine AWS Update Triggered a Global Cloud Outage?

Initially, AWS identified the root cause of the DNS disturbance affecting the AWS DynamoDB endpoint and resolved it within 3 hours. However, EC2 subsequently crashed, which is responsible for creating virtual servers.

This EC2 function is integrated with DynamoDB, but after the database was lost, the EC2 stopped working. Later, the load balancer service was disrupted, causing network issues.

When these three core services stopped responding, AWS services suddenly experienced a chain of failures and crashes.

Lambda, CloudWatch, SQS, and 75+ other services were affected by this outage. Now you can understand how massive it is.

Because servers lost communication, everything just paused for 15+ hours, and that's an unbearable situation. Nowadays, when everything is moving to the cloud and everything is accessible, this pause was hard to swallow.

All the services were mapped and integrated, thus requests piled up and crashed in the queue, so it took a whole day to get back on track.

Now, many news sites are circulating a headline that cloud outage can happen again so it's better to be proactive and have a plan to prevent the issues.

They confirmed that the problem started with DynamoDB, but the twist is even more foolish. What's happening inside AWS is that they're just completing their weekly testing, so they pushed the update, but it went wrong—a bad one that crashed the database and took down all the web apps and sites, leaving them in a non-working state.

Let's jump into learning more about how to detect cloud outage and fix it, and how to ensure the application's availability.

How to Discover the AWS Services Outage?

If you encounter an unexpected failure when accessing any application or website, the app may be crashing and unavailable at the moment due to an uninstalled update. But in another way, the problem could be related to the cloud, which is causing the app or website to fail to load.

Let's detect what may trouble here causing global cloud outage:

Increase in Service Response Time

If you're experiencing delays accessing any AWS app or service that's taking longer than usual, and this issue persists for an hour, it may be due to an outage, a failed request, or a delayed response.

AWS Dashboard Reflects the Service's Health

Visit the official source to identify the scope and root of the issues affecting the applications.
Navigate to the AWS service health dashboard, which provides a comprehensive view of the latest updates on AWS services.

Social Media Updates

Whenever such incidents occur, the relevant authority issues a circular on the official pages of major social media platforms so everyone can understand what has happened.

Use third-party support services and tools if other users have reported the same problems. Stay calm, you're not the one.

Cascading Effect Creates Disturbance

If it's a cascading effect, it must disrupt other connected services across all regions, even if the app operates normally by default. Still, the DNS server or a related component encounters unpredictable issues.

Let's jump into the cloud outage recovery tactics to save from the upcoming disaster.

5 Ways to Recover from an Outage or Cloud Disaster

Outages are one of the most annoying things, just like headaches. After these mishaps, restoring the system's availability is a hectic task. Cloud service providers use the following tactics to recover from outages.

AWS Route 53, elastic load balancing, or other failover mechanisms can automatically redirect you to a safer space to manage the traffic and availability.
All cloud service providers offer disaster recovery strategies and plans. So follow their user manual or books to deal with such circumstances.
Manual failover mechanisms are good, but don't forget to utilize the automated failover mechanism provided by default troubleshooting, which boosts uptime through Recovery Time Objectives and Recovery Point Objectives.
Lastly, if all the core AWS services are affected by this outage, nothing we have mentioned above will fix the situation. Backstep and wait for the official AWS announcement confirming that everything is under control and restored.
Don’t forget to perform sanity checking after the cloud outage is over.

How to Ensure Application Availability During a Cloud Outage?

Outages are unpredictable; to reduce downtime and ensure reliability and resiliency, you must know your approach. Let's get to know how to make system outage proof so you don’t need to face it again, like the recent AWS worldwide outage.

Single Server Reliance isn’t Enough

Reduce reliance on a single region server to improve resiliency. Build the architecture to operate applications across multiple AWS regions.

Mapping Hybrid or Multicloud Service Providers

Whether you're a mid-sized, large, enterprise, or startup, to keep your application operating hassle-free even during outages, consider on-premises support and accessibility from other established cloud service providers.

If services are well mapped and connected across AWS and other providers, it will reduce the risk of a single failure or vendor lock-in.

Perform Automated Failovers for Quick Recovery

You can also tailor automated failovers beyond AWS, assuming both worst-case and best-case scenarios. Define them, align them with your specific needs, and periodically refine and test your tactics.

Practicing with RTO, RPO, and DR policies enabled us to survive these cloud disasters.

Offline Mode and Local Caching

Whether it's primary or secondary services, data is a critical asset that can't be neglected. To ensure the application remains available and active in all scenarios, consider adopting local caching or offline functionality so that some applications can continue to function even when offline.

Reattempt Unfulfilled Requests

During the recovery process, not all services are fully restored or active, and some may also fail. So, it would be best to retry the failed requests or use fallback mechanisms to get the services back up and running.

Revisit Service Agreements/ Contract

While accessing any service from AWS or any other cloud service provider. Go through the offerings and support clauses.

How will they provide support in the event of an outage, recovery, process interruption, or escalation?

How will they ensure all components are available?

It's a wrap now!

One thing to say here!
Disasters are common, but what matters is how we deal with it, making our system resilient for the future. Be innovative and proactive, refine the recovery plan to proactively deal with the outage, and stay ahead of the competitors.

Final Words:

Cloud Outages often irritate us, no matter how hard we try to make the architecture perfect. Whether it is for short term or long term outage that causes disruption, keeping the system still. To improve the uptime, having the right strategy and a proactive automated recovery plan is worth it.

The Maze of Flaky Tests isn’t Less than the Nightmares: Cypress Turns Regression into Robust Product with Confidence

Ayushi Shrivastava — Mon, 06 Oct 2025 11:42:00 +0000

The Struggle is Real to solve the manual maze regression and debug the flaky results. Cypress not only resolves headaches but also helps you understand the pain point.

Have you ever been stuck in a regression of testing the app that is scheduled to release within a few days?

Whenever you try to resolve the flaky issues, a new feature or functionality gets disturbed, and the loop continues.

You’re just waiting for that one moment, that one miracle, that the app has no issues, all bugs are fixed, and it's ready to ship, and all your restless nights and hours of regression paid off.

“According to statistics, every minute spent on debugging concurrent requests through manual testing results in a 15% loss in customer engagement.”

Well, you’re not alone in struggling with the situation; software development teams often go through these chaotic cycles, marked by regrets and regression testing, involving manual bug fixes and updates.
The only goal is to ship a brilliant bug-free product. If any bug slips through undetected and the product is released to end-users, it's a crash. It will put the business's reputation under scrutiny.

The development team appointed to deploy an app needs to be both cautious and confident in the practices employed in the development environment.

Get out of this loop now!

Launch Cypress now. It is like a hidden engine integrated into pipelines, preventing crises in the real world. It helps the development team catch bugs and bottlenecks, reducing regressions and test cycles.

Discovering in this blog story in-depth, how it’s transforming the test case workflows, infusing reliability and stability.

Let's Explore Real-world Scenarios that Seem Like a Headache!

Scenario 1: Assume that we are building an app for the e-commerce industry. It contains all the following functionalities: a user login page, profile, history, payment integration, and other features.

Now we need to test if everything synced and is responding according to plan.

If a developer chooses to do it manually, it will take time to detect the bugs or test failures.

Imagine accessing a payment gateway that fails to validate customer credentials, interrupting the login process.

Alternatively, if the user is about to purchase a product, service, or subscription, but the checkout button gets stuck. The user will become frustrated with these false flows and interactions.

Scenario 2:The development team is testing the UI/UX flow functionality to validate the user's KYC. It can throw errors like the following:

The user can’t create the account due to ID rejection.
While the developer is fixing that functionality, it may take longer to respond.

These are not just headaches; it’s a business debt. Cypress ensures the functionality path is reliable by mocking the API, saving development time and maintaining trust across users.

The complaints are endless, and when you initially check, it may seem very small, but it's enough to give a reason why customers will ditch the app.

As humans, QAs can miss the problematic spot or may get frustrated when they need to repeat test journeys.

In that state of frustration, they push the app to market launch. Ultimately, customers will report the bugs. In that case, the developer’s confidence will drop.

How does Cypress Automation Push Up the App Release?

If the app exhibits any unexpected behavior or lags while accessing a feature, users may consider uninstalling the app or switching to alternative, competitor app options. With Cypress, the problem is resolved.

In a conventional QA cycle, the development team must start from scratch every time they fix a bug. It requires a lot of rework, delaying the timelines. If we integrate Cypress, it eliminates the need for human intervention with every tap. It is programmed to tackle all issues automatically, breaking the loop of repetitive taps to validate the interactions.

Cypress is worth it:

Uninterrupted feature tracing covering all test journeys
Flags the failures/ critical issues in real-time
There is no need to perform a manual fix and validate every flow and interaction.

It's the collaborative effort of the developer and QA professional to build an intuitive, interactive, and responsive experience for every action within the production phase, before it is shipped to the end user. With Cypress, it is easy to speed up app launch.

Cypress: An All-Rounder Tool for Modern World Quality Analyst

Cypress is a JavaScript-based 360-degree testing tool to automate the work QA does in the development ecosystem. A developer's tech stack is incomplete without this tool. It quantifies the racks in minutes and escalates the quality of the app.

We can indeed manage the testing manually, but testing 100+ functionalities repeatedly isn’t realistic. Cypress is a robust and reliable testing framework relevant to the next generation of bug-free application execution.

It is the preferred choice for automation experts, managing end-to-end (E2E) testing. Abstracts the layers of automation for successful cross-browser testing and continuous integration/ development.

Suppose any app takes 10 hours to resolve flaky false tests, maintain Selenium Scripts, address server delay time, and conduct manual testing.
In that case, Cypress will save them from wasting their precious time and efforts, allowing them to focus on another project.

Cypress shreds off the load of QAs, completing the functionality testing in minutes. You may have heard about Selenium and Playwright, but Cypress surpasses them all with its unique set of capabilities.

If you haven't integrated Cypress yet at your workplace, it's an enormous technical debt that multiplies with every repeated sprint. Get out of FOMO by integrating Cypress into your system.

Why Developers and QA Trust in Cypress over Selenium?

To evaluate the potential bugs, false failures, or problematic scenarios, developers widely integrate Selenium in their systems. However, it also encounters the challenges:

Flaky tests because of manual wait and time intervals
Complex setup configurations
An extended server response time slows down the text execution

Cypress is a comparatively better automation tool for eliminating bugs and providing developers with relief from the endless test cycle loop, offering proper visibility of errors and suggestions for fixes.

It is developer-friendly.
Offers the visual representation of each test and bug
Integrate well in agile and DevOps development sprints
Improve user experience and product market release.

Only a single sprint doesn't validate that the app is perfect to release. The developer and QA need to perform multiple sprints multiple times. Manual testing extends the release time as the team spends hours on fixing false failures.

Customers don’t like a troubled app; they want a seamless onboarding experience and smooth interaction with each tap wherever they the interface.

In case the login failed, the checkout button doesn’t respond, or the test script is flaky.

Rather than a technical bug, it wastes a complete sprint time, impacts revenue, and disappoints customers.

That’s where Cypress enters and transforms the real picture. Not just an automation weapon, but the answer to all the problems developers have been waiting for.

How Does Cypress Work Under the Hood?

To make the Cypress drive in action, the secret lies in its architectural engine. It utilizes the GUI or Test Runner, the Cypress Server, and the browser to test the app behavior.

Comprehensive GUI View
GUI enables accessibility to interact with test journeys and results that can be viewed in a parallel browser, improving the efficiency of the test suite.

Backend: Node.js Server
The backend server of Cypress utilizes a dual-server architecture to synchronize the interaction between the test runner and the browser. Both run efficiently, managing the process in parallel with Node.js.

Browser
It displays the actual test execution runs, accessing the Cypress Protocol, which allows control over the browser, DOM, and network requests/responses.

Capabilities of Cypress that Impress Developers

- Code and Configure with the Universal JS Stack
Nowadays, React, Angular, and Vue are worth launching dynamic solutions. These JavaScript-based frameworks are the developers' first preference in the modern world, and Cypress itself is built in JavaScript.

- Intuitive and Interactive Framework
Beyond control and convenience, it is designed to address the pain points of development enthusiasts, saving hours on manual test runs and driving efficiency, reliability, and quality as an exceptional weapon.

- Debug Effortlessly
Automatic bugs and bottlenecks diagnosis, and built-in troubleshooting tools accessibility. QAs can watch what’s happening through visual representation, push the correct codes on the spot, and rerun tests.

It's exhausting to switch on different tech stacks for styling, scripting, and configuring functionality. Thus, if any developer isn’t involved in the process from the start, it would be difficult to steer the ship confidently.

Now that we have understood the Cypress engine, let’s explore its features.

Features of Cypress: What Makes this Test Automation Tool Stand Out?

QAs can adapt this modern world testing framework to eliminate inefficiencies and shorten the market release time, utilizing its capabilities. Let's go through the dashboard features, grab the dev team's attention one by one:

Resume in Realtime Without the Need to Reload

Cypress resume from the point you tracked and tweak out the piece from Cypress. Access the capabilities and receive the feedback from the built-in system, and process confidently.

Automated Wait Intervals

Humans tend to know how long they need to wait, as long as the activities are still in progress or have been completed. Cypress just flipped the script, and it's intelligent enough to tackle the wait durations for the time elements loading.

Check Test Runs in Browser

You can take snapshots of tests from the browsers; these are clickable and serve as a reference in the event of troubleshooting.

Understand Errors in-depth

No need to feel miserable, you can get the status in real-time with a description. The error messages provide a detailed description of the root cause and indicate the specific changes made. QAs can easily track and read the logs from the stack.

Responsive in Poor Network Conditions

No need to stress your head if the network is not stable. Cypress lets you mock, stub, and secure API calls even when the network is slower. Backend services are interrupted, but it’s still possible to test the app's functionalities.

If you're tired of flaky code and repetitive manual test cycles, why don’t you launch Cypress? Within a few minutes, you’re ready to test the app's quality and identify inefficiencies hidden across 100s of functionalities.

Read this step-by-step guide from Cypress to launch Cypress, resolve the app complications, and optimize for the best quality.

Knowing only the installation process isn’t enough; you also need to be familiar with the proper practices to fight the endless battle like a pro. Many have applied them to skim and ship faster.

9 Best Cypress Practices to Perform Debugging for the Dev Team

While preparing for app testing with the Cypress automation tool, optimize the CI/CD pipeline to minimize technical issues and manage test write-ups and journeys efficiently and independently. Don’t miss these practices that QAs prefer within the dev ecosystem.

Practice # 1: Concise and Feature-specific Tests

Tests with lengthy scripts or those that have extensive durations seem overwhelmed. Write one for a single feature or functionality journey. It gives them sufficient time to fix the failures without getting exhausted, and they can be identified promptly.

describe('Login Feature', () => {
  it('should log in with valid credentials', () => {
    cy.visit('/login')
    cy.get('#username').type('admin')
    cy.get('#password').type('password123')
    cy.get('button[type=submit]').click()
    cy.contains('Welcome, admin').should('be.visible')
  })
})

Practice # 2: Specific test names

If the intent is clearly defined with the test name. It will reduce the chances of redundancy and confusion, makes easy to understand, and be remembered for future QA tasks.

describe('User Profile Update', () => {
  it('should allow user to update profile picture', () => {
    // clear test intent is defined
    cy.visit('/profile')
    cy.get('input[type=file]').attachFile('profile.png')
    cy.contains('Profile updated successfully').should('be.visible')
  })
})

Practice # 3: Feature a Clear Folder Structure

Create independent folders to organize all: features, functionalities, user stories, and test journeys files. Having organized in the proper structure, it will resolve all the tension.

// Suggested structure
cypress/
  e2e/
    auth/
      login.cy.js
      register.cy.js
    cart/
      add_to_cart.cy.js
      checkout.cy.js

Practice # 4: Maintain Consistency using Fixtures

It's worth using Fixtures to deal with a wide array of scenarios for the startup. Whenever we need to test the journeys, the database data is automatically downloaded at startup and can be easily cleaned after the test cycles are completed.

// cypress/fixtures/user.json
{
  "username": "testUser",
  "password": "securePass"
}

// cypress/e2e/login.cy.js
describe('Login with Fixtures', () => {
  it('logs in using fixture data', () => {
    cy.fixture('user').then((user) => {
      cy.visit('/login')
      cy.get('#username').type(user.username)
      cy.get('#password').type(user.password)
      cy.get('button[type=submit]').click()
      cy.contains('Dashboard').should('be.visible')
    })
  })
})

Practice # 5: Manage Initial and End Hook Setup

Define every task cycle with a distinct hook setup to isolate and prevent interruptions. Using beforeEach() and afterEach() at every setup and cleanup of the task will make things clear.

describe('Hooks Example', () => {
  beforeEach(() => {
    cy.visit('/login')
  })

  it('logs in successfully', () => {
    cy.get('#username').type('admin')
    cy.get('#password').type('password')
    cy.get('button[type=submit]').click()
    cy.contains('Dashboard').should('be.visible')
  })

  afterEach(() => {
    cy.clearCookies()
    cy.clearLocalStorage()
  })
})

Practice # 6: Improve Readability using Commands

You know the test cycles/ tasks are repetitive; this sometimes creates a mess or a conflicting situation. To improve the clarity and readability, simplify things using custom commands.

// cypress/support/commands.js
Cypress.Commands.add('login', (username, password) => {
  cy.get('#username').type(username)
  cy.get('#password').type(password)
  cy.get('button[type=submit]').click()
})

// usage
describe('Login Tests', () => {
  it('logs in with valid credentials', () => {
    cy.visit('/login')
    cy.login('admin', 'password')
    cy.contains('Dashboard').should('be.visible')
  })
})

Practice # 7: Keep the Count Low of Assertions

Be wise when using assertions to validate app behaviors. If you apply too many assertions, it will become difficult to trace the root cause of the failure encountered.

describe('Product Page', () => {
  it('should load product details', () => {
    cy.visit('/product/1')
    // Keep only essential assertions
    cy.get('.product-title').should('be.visible')
    cy.get('.price').should('contain', '$')
  })
})

Practice # 8: Dashboard Accessibility

Take a glance at every test journey and track its results through the Cypress Dashboard. Be aware of what and when failures occur so that you can address them promptly.

// Run this to view tests in Dashboard mode
npx cypress run --record --key <your-cypress-dashboard-key>

Practice # 9: Adapt the Rule of Continuous Integration

Automate the testing process, prioritizing continuous integration. Ensure that everything is in sync and processing without skipping any functionality. If any complications are encountered, they can be captured in this phase before pushing it up for launch.

We’ve reached the endpoint, and the thought is clear: Cypress is not another tool; it's a productivity booster for the dev team.

How do we leverage AI to build Cypress Automation for our customers?

How To Write Unit Tests in React? A Detailed Guide

Ayushi Shrivastava — Fri, 14 Apr 2023 07:33:15 +0000

React unit testing is a testing method where an individual or small unit of codes or components of the software are tested. In the context of React, a "unit" can be a single component or a small piece of logic within an element. React unit testing aims to validate that each unit of the app is working as intended.

This guide provides a quick introduction to writing React unit tests. I will cover the basics of setting up the testing environment, writing simple tests, testing components and hooks, advanced testing techniques, and best practices for react unit testing in app development.

Let's start this quick guide without waiting a second.

Before going ahead, you can read more about:

Difference between Unit Testing and Integration Testing

Learn about the key differences between unit testing and integration testing in software development, including what they are, why they are important, and their benefits. Discover the best tools and testing approaches to rectify any confusion you may have between the two testing methods.

Creating a React Unit Testing - Step-by-Step

Setting Up the Environment

Before we can start writing React unit tests, we must set up our testing environment. It involves installing a React testing library and configuring the testing environment.

A popular React testing library is Jest, which Facebook maintains. To install Jest, you can use npm or yarn:

npm install --save-dev Jest

Or,

yarn add --dev Jest

So, next, we need to configure the testing environment. It typically involves creating a "jest.config.js" file in the project's root and specifying the configuration options. For example, you can specify the test environment, test file extension, and test command:

module.exports = { 
  testEnvironment: 'jsdom', 
  testMatch: ['**/__tests__/**/*.test.js'], 
  testCommand: 'jest' 
};

In addition to Jest, we also need to install some test utility functions to make our React unit tests easier to write. A popular library for this is "@testing-library/react." You can install it with the below-listed command:

npm install --save-dev @testing-library/react

With the React testing library and test utility functions installed; we are now ready to start writing tests. The following section will cover how to write a simple test in React.

Once you have installed the necessary React testing library and set up your testing environment, you can start writing your tests. To do it, you must create a "*.test.js" file in your project and import the necessary dependencies. For example,

import React from 'react'; 
import { render } from '@testing-library/react'; 
// your component that you want to test 
import MyComponent from './MyComponent'; 
describe('MyComponent', () => { 
  // test case 
  it('renders correctly', () => { 
    const { getByText } = render(<MyComponent />); 
    expect(getByText('Hello, World!')).toBeInTheDocument(); 
  }); 
});

In this example, we are using Jest's "describe" and "it" functions to structure our test. The "describe" function is used to group related tests, and the "it" function defines a single test case. The "render" function from "@testing-library/react" is used to render the component under test, and the "getByText" function is used to retrieve elements from the rendered component based on their text content.

Once you have written your tests, you can run them using the npm test or yarn test command. Jest will then execute your tests and provide a report of the results, including any failed tests.

Setting up the testing environment for React is the first step in writing unit tests. Installing the necessary React testing library and configuring the background ensures that your tests will run smoothly and accurately.

Writing a Simple Unit Test in React

When writing tests for a React component, we typically structure them using Jest's "describe" and "it" functions. The "describe" function is used to group related tests, while the "it" function defines a single test case.

Here's an example of the structure of a simple test:

describe('MyComponent', () => { 
  it('does something', () => { 
    // Test logic goes here 
  }); 
});

This example defines a test for a component called "MyComponent." The "it" function describes a single test case, checking that the element "does something."

Testing a React Component

We first need to render a React component using a react testing library such as "@testing-library/react" to test a React component. We can then make assertions about the component's behavior and output using Jest's "expect" function and various test matchers.

Here's an example of testing a React component:

import React from 'react'; 
import { render } from '@testing-library/react'; 
import MyComponent from './MyComponent'; 
 describe('MyComponent', () => { 
  it('renders correctly', () => { 
    const { getByText } = render(<MyComponent />); 
    expect(getByText('Hello, World!')).toBeInTheDocument(); 
  }); 
});

In this sample, we are testing the "MyComponent" component. The render function is used to render the part, and the "getByText" function retrieves elements from the rendered piece based on their text content. Finally, the "expect" function asserts the component's behavior. In this case, we are announcing that the document's text, "Hello, World!" is present.

Test Matchers

Test matchers are used with the "expect" function to make assertions about a component's behavior and output. Jest provides a wide range of test matchers to check various conditions, such as whether a value is equal to a specific value, whether an element is present in the document, and more.

Here are some standard test matchers that you might use when testing a React component:

toBe: Checks that a value is equal to a specific value.
toBeInTheDocument: Checks that an element is present in the document.
toHaveTextContent: Checks that a part has certain text content.

Debugging Failed Tests

If a test fails, Jest will provide an error message indicating why the test failed. This message can be used to help diagnose the issue and determine what needs to be fixed.

In addition to the error message, you can use the debug function from @testing-library/react to inspect the rendered component and view its state. It can be especially valuable when determining why a test has failed.

Here's an example of using the debug function to inspect a rendered component:

import React from 'react'; 
import { render, debug } from '@testing-library/react'; 
import MyComponent from './MyComponent'; 
describe('MyComponent', () => { 
  it('renders correctly', () => { 
    const { getByText } = render(<MyComponent />); 
    const text = getByText('Hello, World!'); 
    expect(text).toBeInTheDocument(); 

    // If the test fails, use debug to inspect the component 
    if (!text) { 
      debug(); 
    } 
  }); 

});

In this example if the test fails and the text "Hello, World!" is not found in the document, the debug function is called to inspect the rendered component. It allows you to see the component's state and determine what might be causing the issue.

Using the techniques discussed in this section, you can write simple and practical tests for your React components and diagnose and debug any issues.

If you are still struggling with debugging, I suggest you should reach to a quality assurance provider.

Testing React Components

Testing State and Props

In addition to testing the output of a React component, it's also essential to test its state and props. It allows you to verify that the component behaves as expected in response to changes in its shape and props.

To test a component's state and props, you can use the render function from @testing-library/react to render the component with specific props and state and then make assertions about the component's behavior and output.

Here's an example of testing a component's state and properties:

import React from 'react'; 

import { render, fireEvent } from '@testing-library/react'; 



import MyComponent from './MyComponent'; 



describe('MyComponent', () => { 

  it('renders with the correct props and state', () => { 

    const props = { 

      name: 'John Doe', 

    }; 

    const { getByText } = render(<MyComponent {...props} />); 

    expect(getByText(`Hello, ${props.name}!`)).toBeInTheDocument(); 

  }); 

});

In this example, the "MyComponent" component is rendered with specific props, and the "expect" function is used to assert the component's behavior and output.

Testing Event Handlers

React components often include event handlers that respond to user interactions, such as clicking a button. To test these event handlers, you can use the "fireEvent" function from @testing-library/react to simulate user interactions and make assertions about the component's behavior and output.

import React from 'react'; 
import { render, fireEvent } from '@testing-library/react'; 
import MyComponent from './MyComponent'; 
describe('MyComponent', () => { 
  it('responds to button clicks', () => { 
    const { getByText } = render(<MyComponent />); 
    const button = getByText('Click Me'); 
    fireEvent.click(button); 
    expect(getByText('You clicked the button!')).toBeInTheDocument(); 
  }); 
});

Testing Components with External APIs

React components often interact with external APIs, such as web services or databases. To test these components, you can use a library such as jest-fetch-mock to mock the API calls and verify that the component behaves as expected.

import React from 'react'; 
import { render, waitForElement } from '@testing-library/react'; 
import 'jest-fetch-mock'; 
import MyComponent from './MyComponent'; 
describe('MyComponent', () => { 
  it('fetches data from an API', async () => { 
    fetchMock.mockResponseOnce(JSON.stringify({ data: 'Hello, World!' })); 
    const { getByText } = render(<MyComponent />); 
    await waitForElement(() => getByText('Hello, World!')); 
expect(fetchMock).toHaveBeenCalled(); 
expect(getByText('Hello, World!')).toBeInTheDocument(); 
  }); 
});

Testing Components with Redux

React components often use the Redux state management library to manage their state. To test these components, you can use a library such as redux-mock-store to create a mock store and verify that the part dispatches the correct actions and updates the store as expected.

import React from "react"; 
import { render, fireEvent } from "@testing-library/react"; 
import { Provider } from "react-redux"; 
import configureMockStore from "redux-mock-store"; 
import MyComponent from "./MyComponent"; 
import rootReducer from "./rootReducer"; 
const mockStore = configureMockStore([]); 
describe("MyComponent", () => { 
  it("dispatches actions and updates the store", () => { 
    const store = mockStore({}); 
    const { getByText } = render( 
      <Provider store={store}> 
        <MyComponent /> 
      </Provider> 
    ); 
    const button = getByText("Click Me"); 
    fireEvent.click(button); 
    const actions = store.getActions(); 
    expect(actions).toEqual([{ type: "CLICK_BUTTON" }]); 
  }); 
});

Testing React Hooks

React Hooks are a new feature introduced in React 16.8 that allows developers to add state and other logic to their functional components. They provide a more convenient and flexible way of managing state and side effects compared to class components.

Testing Custom Hooks

Custom hooks are functions that encapsulate logic and can be reused across multiple components. They can also be tested in isolation, just like regular JavaScript functions.

import { useState } from 'react';  
function useCounter() { 
  const [count, setCount] = useState(0); 
  function increment() { 
    setCount(count + 1); 
  } 
  return { count, increment }; 
} 
describe('useCounter', () => { 
  it('increments the count', () => { 
    const { count, increment } = useCounter(); 
    expect(count).toBe(0); 
    increment(); 
    expect(count).toBe(1); 
  }); 
});

Testing Stateful Hooks

To test stateful hooks in React components, you can use a library such as ‘’@testing-library/react’’ to render the component and access its state and functions.

import React from 'react'; 
import { render, fireEvent } from '@testing-library/react'; 
import Counter from './Counter'; 
describe('Counter', () => { 
  it('increments the count', () => { 
    const { getByText } = render(<Counter />); 
    const button = getByText('+'); 
    fireEvent.click(button); 
    const count = getByText('1'); 
    expect(count).toBeInTheDocument(); 
  }); 
});

Testing Effect Hooks

Effect hooks perform side effects in React components, such as fetching data or updating the document title. To test these hooks, you can use a library such as jest-fetch-mock to mock the API call, verify that the hook makes the expected call, and update the component's state as expected.

import React, { useEffect, useState } from 'react'; 
import { render, waitForElement } from '@testing-library/react'; 
import fetchMock from 'jest-fetch-mock'; 
function FetchData() {const [data, setData] = useState(null); 
 useEffect(() => { 
    fetch('https://api.example.com/data') 
      .then(response => response.json()) 
      .then data => setData(data)); 
}, []); 
return data ? <div>{data}</div> : <div>Loading...</div>; 
} 
describe('FetchData', () => { 
beforeEach(() => { 
fetchMock.mockResponse(JSON.stringify({ data: 'test data' })); 
}); 
it('fetches and displays data', async () => { 
  const { getByText } = render(<FetchData />); 
  const element = await waitForElement(() => getByText('test data')); 
  expect(fetchMock.mock.calls.length).toBe(1); 
  expect(element).toBeInTheDocument(); 
  }); 
});

Advanced Testing Techniques

Testing Performance

Performance testing is an important aspect of writing unit tests, as it ensures that your components render efficiently and do not impact the overall performance of your application. There are a bunch of techniques and tools you can get the help of to test the performance of your React components, including

Measuring the time it takes to render a component with "performance.now()"
Using the React Profiler API to measure the time spent rendering components and identify performance bottlenecks
Using the lighthouse library to test the performance of your pages, including their loading speed and overall performance score

Testing Snapshots

Snapshot testing is a technique for testing the structure and output of your React components. The idea behind snapshot testing is to take a "snapshot" of the component's output and compare it to the previous snapshot to see if anything has changed.

Snapshot testing can be used to catch unexpected changes in the output of your components, such as changes in the structure of your HTML or changes in the values of your component's props. Jest, the popular JavaScript testing library, has built-in support for snapshot testing.

Testing Component with Context

The capability of context in React to circulate information and functions throughout the component tree without the need for manual prop transmission at every step is a valuable attribute. Testing components that use context can be challenging, but there are a few techniques you can use to make it easier:

Using the "TestRenderer" from React testing library to render the component and access its context
Creating a test-specific context provider that can be used to pass context data to your component during testing

Testing Error Boundaries

Error boundaries in React offer the ability to manage and recover from mistakes in your components. Evaluating the efficiency of error boundaries involves creating simulated errors and confirming that the error boundary component appropriately handles and bounces back from the error.

You can simulate errors by throwing exceptions in your component or using the "act" function from React testing library to simulate the mistakes during rendering. You can then use "expect" or other test assertion functions to verify that your error boundary component correctly handles and recovers from the error.

React Unit Testing Best Practices

Writing Clean and Readable Tests

Writing clean and readable tests is crucial for ensuring the maintainability and reliability of your test suite. Some best practices for writing clean and readable tests include the following:

Writing tests that are self-contained and don't depend on external data or state
Using descriptive and clear test names that accurately reflect the purpose of each test
Keeping tests small and focused, only testing a single behavior or feature at a time
Using assertions and matchers that are clear and easy to understand

Reusability of Tests

The capability to use tests repeatedly is a vital aspect of writing unit tests, as it enables you to write tests once and apply them in various locations across your codebase. Some recommended techniques for enhancing the repeatability of your tests include:

Writing tests that are independent of specific components or functions so that they can be reused in different parts of your codebase
Extracting common test logic into utility functions or custom matchers to make it easier to reuse your tests

Automation of Tests

Automating your tests is crucial for ensuring that they run quickly and accurately every time you make changes to your code. Some best practices for automating your tests include the following:

Running tests automatically as part of your build process using a CI/CD tool
Running tests on every push to your codebase using a Git hook or other automation tool
Automatically generating test coverage reports to see which parts of your code are and are not being tested

Maintenance of Tests

Maintenance is an essential part of writing unit tests, as it ensures that your tests continue to be accurate and valuable as your code changes over time. Some best practices for maintaining your tests include

Regularly review and update your tests to ensure they reflect the current state of your code
Deleting or updating tests that are no longer relevant or accurate
Keeping your test code up-to-date with the latest react testing library and best practices

Final Words

In this guide, I've covered the basics of how to write unit tests in React. From setting up your testing environment to testing React components and hooks and using advanced testing techniques, you should now understand how to write and maintain high-quality unit tests for your React applications.

But in difficult and complex projects, you may need a better-helping hand in react unit testing. In this scene, you should get the help of a Quality analyst, or you can hire an experienced React developer.

Ayushi Shrivastava — Wed, 12 Oct 2022 05:36:09 +0000

Managing a full-stack mobile app development is a stressful job. A developer needs to pay attention to the database, front end, back end, and hosting-related things. Now to reduce the headache of developers, Amazon has launched the fantastic product AWS Amplify Studio. It groups the essential components and supports you in developing the application from scratch.

AWS Amplify Studio was released in November 2018 to facilitate stress-free and seamless development. It has a suit of every essential capability required for the mobile, web, or any other UI & framework.

To get started with AWS Amplify Studio, the developer should understand ReactJS, GraphQL, Figma administration, and, most importantly, the database.

Now, if you possess all these things, then head to mobile app development!

Quick Launch of a Full Stack Application with AWS Amplify Studio

Follow this procedure to build a beautiful mobile app from the initial.

The first step is to locate AWS Amplify. Then go to Amplify Studio, and hit Get Started mobile app development. You can sign up with your existing account or try a new one.
You must have thought of a name for your app development project. So in this step, you must enter some App Details to proceed further.
Type a good name in the App name field. And click on Confirm Deployment.
Proceed to Launch Studio to set up the backend Environments for mobile app development. (You can unbox all the cloud capabilities from this container.) Get everything Data, Authentication, Storage, Functions, GraphQL API, REST API, etc.
We need to deploy data models to create & fetch the content from the database. So you can do this in minutes by clicking on Create Data Model. Set Up > Data Section.
Once you have declared all the field and their type, just hit on Deploy. You can specify the relationship and impose authorization rules.

If you are willing to make some modifications look on top from Manage. You can quickly add/ modify content from the sidebar options. If you want to Autogenerate data, head to Actions > Auto Generate Data.

UI Design Import

We reached the exciting part of the Full stack development, UI. Figma is not a miserable thing for UI/UX designers. You can access the default Figma Template for UI or import it at Amplify Studio.

You can sync your previous Figma work with AWS Amplify Studio. Like the Canva design tool, Figma also has a sharing feature. You must get the link from Figma and paste it to Amplify Studio.

Data-UI Component Connectivity

We have a data model and UI. Now it's time to establish connectivity for better workflow and accessibility.

What you have to do is select the component from Studio and hit Configure.
Set a component property from the top Add Property, give it a name, and define the type for the same.
You can update and edit any components and set the link as needed. Choose the data. Choose an attribute and put it with the propertytype.elementname.
You can confirm your work by hitting on shuffle preview data to know if it is set up or not. Whether the data is connected with the respective data or not.

Add Collection to group component(blog)

You can fetch the entire list at a time and can see all your blog post statuses together. For this, you need to create a collection to store data inside.

Hit on the create collection and give a nice name to identify quickly.

You can customize the alignment and space between the cards for the perfect view.

Apply the filters to view only selected category blog posts. Additionally, you can click on View/edit and manage these datasets.

Pack Up to UI and Dataset to React app

We have prepared datasets and UI components and are done with connectivity. Now we need to pack it in React App. So, follow the below code:

npx create-react-app amplify-studio-blog
cd amplify-studio-blog

Next, you can access App ID. for this, look for localsetup instructions > amplify pull command.

If you want to run the command and explore other features. Do so. Proceed with the browser popup and access Studio. Access default. Next, follow this code:

npm install @aws-amplify/ui-react aws-amplify

It will do the installation of Amplify React Component + Amplify Libraries.

When you visit the text editor, you’ll see that a /amplifydirectory is here. Also, there are /src/models /src/ui-components created. Ui-components will store all your human-readable format React code.

We must link the Amplify app and the front end to fetch your blog list. For this, we will create an index.js file and add the code.

import config from './aws-exports'
`import Amplify from 'aws-amplify'

Amplify.configure(config)

It’s time to remove the App.js component. We need something for styling that we need to import a css file. Here is Amplify CSS. Then type to invoke the component AmplifyProvider and also the PostCollection.

import '@aws-amplify/ui-react/styles.css'
import { AmplifyProvider } from '@aws-amplify/ui-react'
import PostCollection from './ui-components/PostCollection'

This AmplifyProvider component will manage the styling for all the child components.

Next, we will create a function and add AmplifyProvider and collection(that you previously created containing all the data).

function App() {
  return (
    <AmplifyProvider>
      <BlogCollection />
    </AmplifyProvider>
  )
}
export default App

After doing this, you can see the posts fetched from the database. If the font is not displaying properly, you can modify the index.css for better visibility and function.
Access the following lines:

`@import url('https://fonts.googleapis.com/css2?family=Inter:slnt,wght@-10..0,100..900&display=swap');

You can add functionality and accessibility to the components and make them more attractive. For example, if you have data on multiple pages adding pagination will help you to navigate directly to the page faster.

You just need to add this single line:
<PostCollection isPaginated itemsPerPage={5} />

Authentication

You can set the authentication to make your app more interactive, secure, and robust.
Go to Amplify Studio and look for Setup > Authentication

A different format is given to set authentication; you can select default, password, or other attributes and deploy with the one. Drive the amplify pull command to manage the changes to your app.

withAuthenticator is an essential higher-order component than managing the pepper authentication action to our react app.

import { AmplifyProvider, withAuthenticator } from '@aws-amplify/ui-react'

It's time to wrap up the same in components.
export default withAuthenticator(App)
Theme customization is allowed here to make your app appearance more appealing and beautiful. Either you can access the Figma pallet or UI component theming. You can style your components through JS objects, css code, design tokens, etc.

At any moment, if you are willing to make changes to your component style. Just visit Studio UI library > Sync with Figma. Once done, run the amplify pull command to update the changes to the app.
