This video explains the basics of unit testing, test-driven development, and code coverage in Python. The "holy grail" of unit testing is to reach 100% code coverage. However, code coverage is not a perfect metric, as you'll see in this video. I'll go through an example in Python showing you how to add unit tests, interpret coverage reports, and how the process of test-driven development works. And then I'll end the video with covering two mistakes I've seen developers make when writing unit tests and interpreting their coverage reports.
