Automated Testing for React and ASP.NET Core

Building modern web applications requires confidence that your code works as expected, even as it grows. By adopting automated testing early, you can catch bugs before they reach production and deploy updates with total peace of mind. This text-based course guides you through the foundational concepts and practical techniques of automated testing for both React frontends and ASP.NET Core backends. You will transition from manual debugging to writing structured, reliable tests that verify your application's behavior automatically. What you'll learn: 1. Understand fundamental testing terminology, from unit and integration tests to end-to-end strategies. 2. Write robust unit tests for React components using modern testing libraries and virtual DOM rendering. 3. Build reliable backend tests for ASP.NET Core APIs using xUnit and in-memory databases. 4. Implement integration tests that verify seamless communication between different layers of your application. 5. Mock external dependencies and API calls to isolate your tests and ensure consistent execution. 6. Practice modern testing workflows that fit into continuous integration pipelines to maintain high code quality. You will start with core testing principles before diving into step-by-step written guides for configuring testing environments, writing your first assertions, and structuring test suites for real-world scenarios. This course is designed for beginner developers who have basic familiarity with React and ASP.NET Core but are new to automated testing. No advanced testing experience is required.
