Install Cypress and Do some automated testing

Cypress is a powerful JavaScript end-to-end testing framework that enables developers to test web applications efficiently. Here are some common use cases for Cypress testing:

Functional testing: Cypress can be used to ensure that the web application is functioning correctly. Functional testing is performed to ensure that the application’s features are working as expected.

Regression testing: Cypress can be used to check whether any new changes to the application have introduced any issues or broken any existing features.

User acceptance testing (UAT): Cypress can be used to test whether the web application meets the requirements specified by the users. UAT is performed to ensure that the application satisfies the users’ needs and expectations.

Integration testing: Cypress can be used to test whether different parts of the application are integrated correctly. Integration testing ensures that the individual components of the application work together seamlessly.

Accessibility testing: Cypress can be used to test the web application’s accessibility features. Accessibility testing ensures that the application can be used by people with disabilities and meets the Web Content Accessibility Guidelines (WCAG).

Security testing: Cypress can be used to test the web application’s security features. Security testing ensures that the application is secure from malicious attacks and vulnerabilities.

To install Cypress and run a test on follow these steps:

Install Node.js and npm on your computer, if you haven’t already. You can download them from the official website:

Open a terminal or command prompt and navigate to your project directory.

Initialize a new Node.js project by running the following command:

npm init -y

Install Cypress as a dev dependency by running the following command:

npm install cypress --save-dev

Once Cypress is installed, open the Cypress Test Runner by running the following command:

npx cypress open

This will open the Cypress Test Runner, which allows you to write and run tests in a graphical user interface.

In the Cypress Test Runner, click the “Create New Test” button to create a new test file.

Here’s a Cypress script to open and click a link named “DevOps”:

describe('Open and click DevOps link', () => {
it('should click the DevOps link', () => {

This script uses the visit() command to navigate to and contains the () command to find the link with the text “DevOps”. It then uses the click() command to click on the link.

Make sure that the text “DevOps” is an exact match for the link you want to click. Cypress may click the wrong one if there are multiple links with the exact text. In that case, you can use a more specific selector to target the correct link.

There are many tests that can be added using Cypress. Here are a few examples:

Form submissions: You can use Cypress to test form submissions, including form validation and error handling.

Navigation: You can test the navigation between pages on your site, including clicking links, submitting forms, and using browser navigation buttons.

Authentication: You can test user authentication workflows, including logging in and out, and verifying that unauthorized users can’t access restricted pages.

UI interactions: You can test user interface interactions, such as clicking buttons, hovering over elements, and dragging and dropping items.

API testing: You can use Cypress to test your site’s APIs, including verifying that the correct data is returned and that error handling is working correctly.

Accessibility testing: You can use Cypress to test the accessibility of your site, including verifying that all elements have appropriate alt text and that the site can be navigated using only a keyboard.

Load testing: Cypress can be used to test the application’s performance under heavy load. Load testing is performed to ensure that the application can handle a large number of concurrent users without crashing or slowing down.

describe('Load testing example', () => {
  before(() => {
    // set up the test environment

  after(() => {
    // clean up the test environment

  it('should handle 1000 requests in less than 10 seconds', () => {
    const requests = []

    // create 1000 requests
    for (let i = 0; i < 1000; i++) {
          method: 'GET',
          url: '/api/test',

    // measure the time it takes to complete all the requests
    const startTime = new Date().getTime()

    cy.wrap(Promise.all(requests)).should((responses) => {
      const endTime = new Date().getTime()
      const duration = endTime - startTime
      expect(duration) // less than 10 seconds
      expect(responses).to.have.lengthOf(1000) // all requests completed
      expect(responses.every((response) => response.status === 200)) // all requests succeeded

These are just a few examples of the types of tests you can add using Cypress. The best tests to add depending on your specific site and business needs.
