Overview/Description

This 8-video course explores several Python applications for testing, including the unit-test framework, pytest, and doctest. To take this course, you should have prior experience with Python programming, and familiarity with running commands from a Linux shell. This course focuses on doctests, and examines how the doctest module allows the definition of simple python tests within the docstrings in your source code. You will examine what syntax is needed when manually running tests from a Python shell, and how to copy over shells. Next, you will learn to capture the output and use it in your source file, then how to create an executable document for your source. This course demonstrates packaging a readme file, and the tests for a Python module. Learners will examine the bundling of documentation and tests into a single executable file. You will learn how to Ellipsis directive to address unpredictable outputs. Finally, you will learn to instruct your doctests to ignore whitespace characters within the outputs of a test by using the normalized whitespace directive.
