You do not have to be an expert or even a journeyman in Python to learn how to use pytest to create test frameworks for programs, functions, packages, modules, and APIs. After learning the Python concept and functions needed for writing pytest, you will learn how to use assert to test Python. This is followed by an introduction to parameters and fixtures to reduce typing and create reusable passages of code. Mocking is introduced to show how to test an external interface. A simple method of using classes and directories is explored for the management of tests.
