Python’s doctest: Document and Test Your Code at Once
Are you interested in writing usage examples for your code that work as documentation and test cases simultaneously? If your answer is yes, then Python’s doctest module is for you. This module provides a testing framework that doesn’t have too steep a learning curve. It’ll allow you to use code examples for two purposes: documenting and testing your code.
Apart from allowing you to use your code’s documentation for testing the code itself, doctest will help you keep your code and its documentation in perfect sync at any moment.
In this tutorial, you’ll:
- Write
doctesttests in your code’s documentation and docstrings - Understand how
doctestworks internally - Explore the limitations and security implications of
