Testing FrameworkJest is a widely-used JavaScript testing framework known for its simplicity, speed, and built-in test runner.
@testing-library/react is a popular testing library for testing React components, focusing on user-centric testing.
Chai is an assertion library often used with Mocha or other testing frameworks to create expressive and readable test assertions.
Mocha is a flexible testing framework that provides test structure and organization, often used in combination with assertion libraries like Chai.
Cypress is an end-to-end testing framework that enables developers to write tests for web applications with a focus on automation and reliability.
Puppeteer is a headless Chrome browser automation library that is commonly used for browser testing and web scraping.
Karma is a test runner that allows developers to execute tests across different browsers and platforms, often used with testing frameworks like Jasmine or Mocha.
Enzyme is a testing utility for React that provides tools for testing React components and their behavior.
Jasmine is a behavior-driven development (BDD) testing framework known for its readability and expressive test syntax.
React Component TestingJest includes built-in support for testing React components and provides utilities for rendering, mocking, and asserting component behavior.
@testing-library/react is designed specifically for testing React components in a user-centric way, encouraging best practices.
Chai can be used for testing React components, but it typically requires additional libraries like Enzyme for rendering and manipulation.
