What is Doctest Module in Python
The Doctest Module finds patterns in the docstring that look like interactive shell commands. The input and expected output are included in the docstring, then the doctest module uses this docstring for testing the processed output. After parsing through the docstring, the parsed text is executed as Python shell commands and the result is compared with the expected outcome fetched from the docstring.
Testing in Python using Doctest module
Docstrings in Python are used not only for the description of a class or a function to provide a better understanding of the code and use but, also used for Testing purposes. Testing is a critical aspect of software development that ensures code functions as expected and guards against bugs. In Python, the Doctest module provides a simple yet powerful way to test code by embedding test cases within docstrings.
