Testing your code allows you to check that your logic works as expected every time, giving you code confidence, lowering stress levels, and allowing you to deliver faster results.

In this quick, one-hour tutorial, we dive into what unit testing is and why it is important for all developers, regardless of their confidence and experience.

The earlier you start incorporating unit tests into your code base, the better - but it’s never too late. That means that this course is suitable for both newbie coders and those already working in the field who want to level up.

This course covers test grouping, test cases, debugging tests with focus, spies, and more in just one hour, and it contains plenty of challenges to cement your new knowledge.
