Cypress
A fast, easy, and reliable end-to-end testing framework for modern web applications.
Price: Freemium
Description
Cypress is a modern JavaScript-based testing framework designed for developers and QA engineers to write and run end-to-end, integration, and unit tests for web applications. It operates directly in the browser, providing real-time reloads, automatic waiting, and debugging capabilities that make testing faster and more reliable. Unlike Selenium, Cypress runs tests directly in the browser, giving developers full control over the application, network traffic, and local storage, leading to more stable and faster tests, particularly for modern JavaScript frameworks like React, Angular, and Vue.js.
How to Use
1.Install Cypress as an npm package in your web project using `npm install cypress --save-dev`.
2.Write test files using JavaScript or TypeScript to describe user interactions and expected application outcomes.
3.Open the Cypress Test Runner via `npx cypress open` to visually run tests in a real browser.
4.Interact with your application during tests, inspect elements, and debug issues in real-time using developer tools.
5.Integrate Cypress into your CI/CD pipeline for automated testing upon code changes, ensuring continuous quality.
