Steven F. Lott

Steven Lott has been programming since computers were large, expensive, and rare. Working for decades in high tech has given him exposure to a lot of ideas and techniques, some bad, but most are helpful to others. Since the 1990s, Steven has been engaged with Python, crafting an array of indispensable tools and applications. His profound expertise has led him to contribute significantly to Packt Publishing, penning notable titles like "Mastering Object-Oriented," "The Modern Python Cookbook," and "Functional Python Programming." A self-proclaimed technomad, Steven's unconventional lifestyle sees him residing on a boat, often anchored along the vibrant east coast of the US. He tries to live by the words “Don't come home until you have a story.”

Unit testing with pytest

We can create unit tests using a library that provides a common framework for the test scenarios, along with a test runner to execute the tests and log results. Unit tests focus on testing the least amount of code possible in any one test. The standard library includes the unittest package. While widely used, this package tends to force us to create a fair amount of boilerplate code for each test case.

One of the more popular alternatives to the standard library unittest is pytest. This has the advantage of letting us write smaller, and more clear, test cases. The lack of overheads makes this a desirable alternative.

Since pytest is not part of the standard library, you'll need to download and install it yourself. You can get it from the pytest home page at https://docs.pytest.org/en/stable/. You can install it with any of the installers.

In a Terminal window, activate the virtual environment you're working in...
