How to Write Your First Cypress Test [With Examples]

Cypress is a JavaScript testing framework that allows developers to write, run, and debug tests directly within the browser. It provides an in-built tool called 'Cypress Studio' for creating test cases without writing code. This makes it accessible to individuals with limited programming knowledge. Cypress also supports manual script-writing using JavaScript or TypeScript. The framework integrates well with Mocha, a popular testing library, and Chai assertions for validating conditions in tests. To write your first Cypress test, you can either use 'Cypress Studio' or write the script manually. With 'Cypress Studio,' users can record their interactions with the application being tested, which are then automatically recorded as steps in the backend test file. This approach is particularly useful for users who may not have extensive programming knowledge. Alternatively, you can write your Cypress tests using JavaScript or TypeScript. To do this, you need to set up Cypress and create a test file under the 'cypress/e2e/' directory. The describe() block groups related test cases together, while the it() block defines individual test cases. Hooks such as before(), beforeEach(), after(), and afterEach() can be used for setup and teardown tasks. Cypress tests can be executed in headed or headless mode on a local machine. To run tests in the cloud, you can use platforms like LambdaTest, which provide scalability and parallel testing capabilities. By integrating Cypress with LambdaTest, users can automate their tests across different browser versions and environments to ensure compatibility and reliability of web applications.
