The unittest Module

Learn how to use the unittest module in Python to perform unit testing.

We'll cover the following

Creating unit tests

The unittest module is a great option with which to start writing unit tests because it provides a rich API to write all kinds of testing conditions, and since it's available in the standard library, it's quite versatile and convenient.

The unittest module is based on the concepts of JUnit (from Java), which, in turn, is also based on the original ideas of unit testing that come from Smalltalk (perhaps this is the reason behind the naming convention of the methods on this module), so it’s object-oriented in nature. For this reason, tests are written through classes, where the checks are verified by methods, and it’s common to group tests by scenarios in classes.
