In this course, you'll learn how to write simple, practical unit tests with Vitest to make your code more reliable. We'll start with the basics - like how to setup Vitest and make a simple test by writing assertions, then move into things like mocks, spies and async tests. The lessons are focused and easy to follow, so the whole process feels approachable even if you’ve never tested a line of code before.

By the end, you’ll have a solid grounding in unit tests, and a much better sense of how to keep your code bug-free.
