JavaScript Testing
JavaScript Testing refers to the practice of writing and running automated tests for JavaScript code to verify its correctness, reliability, and performance. It involves using testing frameworks, libraries, and tools to create unit tests, integration tests, and end-to-end tests for web applications, Node.js backends, and other JavaScript-based systems. This ensures code quality, prevents regressions, and supports agile development practices like test-driven development (TDD).
Developers should learn and use JavaScript Testing to build robust, maintainable applications, especially in complex projects where manual testing is inefficient. It is crucial for catching bugs early, facilitating refactoring, and ensuring code works as expected across different environments and browsers. Key use cases include testing React components, Node.js APIs, and full-stack web applications to improve deployment confidence and reduce production issues.
