How do you know that your code works if you don't test it? Simple — you don't! Thankfully, testing is easy and fun with pytest, Python's most popular test framework. In this session, Andrew will show you how to use pytest like a pro. Everything will be done LIVE — we will set up a project from scratch and automate a series of tests to show how to use the pytest framework. By the end of the session, you'll be able to write your own tests to protect your code!
