Cypress is a next-generation front-end testing tool built for the modern web.

It addresses the key pain points developers and QA engineers face when testing modern applications.

Cypress is fast, reliable, and easy to use.

To install Cypress, follow these steps:

Open your terminal.

Run the command: npm install cypress --save-dev

Once installed, open Cypress with the command: npx cypress open

Writing tests in Cypress is straightforward.

Here’s an example of a basic test:

        
describe('My First Test', () => {
  it('Visits the Kitchen Sink', () => {
    cy.visit('https://example.cypress.io')
    cy.contains('type').click()
    cy.url().should('include', '/commands/actions')
  })
})
        
      

This test visits a page, finds a link with the text "type", clicks it, and then checks if the URL includes "/commands/actions".

You can run tests in Cypress using the Test Runner or from the command line.

To run tests from the command line, use the command:

npx cypress run

For more options, refer to the official Cypress documentation.

The Test Runner provides an interactive interface to run and debug tests.

Here are some best practices to follow when using Cypress:

• Keep tests isolated and independent.
• Avoid using cy.wait() for arbitrary periods of time.
• Leverage Cypress’ built-in retry-ability.
• Use fixtures for static data.
• Organize tests and structure them logically.

Following these best practices will help ensure your tests are reliable and maintainable.

Cypress provides extensive documentation and examples to help you get started.
