Course Description

Software unit tests help the developer to verify that the logic of individual pieces of the program is correct. It is vital to the success of refactoring, the act of improving software design without changing the behavior of the system.

In this course, students will learn how to use both Python's built-in unit test module and the Pytest module as a unit testing framework for the Python programming language. This includes the Pytest features of Fixtures and the rich plug-in ecosystem for Pytest. The key unit testing concepts of Behavior-Driven Development (BDD), Test-Driven Development (TDD), Behavior Driven Development (BDD), and Continuous Integration (CI) are also covered. Pytest allows the developer to ensure high test coverage of the code and allows continuing development of new features without having to perform lots of manual tests. Other tools discussed include virtualenv and the Tox testing tool to test in different environments while connecting with a Continuous Integration service like Travis-ci.
