11.4 Doctest
Doctest is a Python module that provides a unique way of testing your program. It encourages you to write documentation that doubles as tests. Essentially, you create code examples in your documentation, and Doctest will then execute those examples as tests.
This approach can be very useful because it encourages you to write comprehensive documentation, and it ensures that your documentation is always up-to-date with your code. Furthermore, Doctest provides an easy way to test individual pieces of code without the need for a separate test suite, which can be very helpful for smaller projects. Overall, using Doctest can be a great way to improve the quality and reliability of your code.
Here is a very simple example:
You can run the test with python -m doctest -v your_module.py.
Each of these testing frameworks has its strengths and weaknesses, and which one to use often depends on the specific needs of your project. But all of them are powerful tools to help you write...
