Modern JavaScript Test Runners: Native Node.js and Vitest

Testing is a cornerstone of modern software development, but configuring heavy testing frameworks can slow you down. Native test runners and modern tools like Vitest offer lightweight, lightning-fast alternatives for validating your code. This text-based course guides you from testing basics to writing robust, automated test suites without the bloat of legacy tools. What you'll learn: - Understand core testing concepts, assertions, and test-driven development principles. - Configure and run tests using the native Node.js test runner without external dependencies. - Write unit tests, integration tests, and asynchronous test suites. - Apply mocking, spying, and stubbing techniques to isolate your code under test. - Utilize Vitest for fast, modern web development testing with instant feedback. - Implement test coverage reporting to identify untested paths in your codebase. Starting with fundamental testing terminology and basic concepts, you will progress through written explanations and code examples, exploring native testing APIs and transitioning to advanced mocking patterns. This course is designed for beginner to intermediate JavaScript developers who want to write clean tests without complex configuration. No prior testing experience is required.
