If you have a working knowledge of Python, you can quickly learn how to use pytest to create test frameworks for programs, functions, packages, modules, and APIs. You will learn how to use assert for testing. This is followed by fixtures to modularize your test code to parameters and fixtures to reduce typing and to create re-useable passages of code. Mocking is introduced to show how to test an interface. A simple method of using classes and directories is explored for management of tests. Lastly, the course explores a method of deciding what needs to be tested and what your test coverage is.
