Unit Testing with Python

by Emily Bache

This course will help you to write good unit tests for your Python code, using tools such as unittest, doctest and py.test. Unit tests should improve code quality, and also support future development.

What you'll learn

This course follows on from the Pluralsight "Python Fundamentals" course, and has more detail about unit testing with Python.

In this Python tutorial we will cover libraries and frameworks such as:

  • Unittest
  • Doctest
  • and Py.test

The aim is to help you to write unit tests that improve code quality, and also support future development. Good unit tests should provide immediate value in terms of reduced debugging and better design, and the investment writing them should pay back over the whole lifetime of your software.
