Frequently Asked Questions (FAQ’s)
1. How to Run Doctest in Python?
To run doctests in Python, you can include test cases in the docstrings of your functions or modules and use the
doctest
module. Executepython -m doctest <module_name>.py
in your terminal to run the tests.
2. How Doctest Matches Expected and Actual Test Output?
Doctest matches expected and actual test output by parsing the docstrings of functions and modules for lines prefixed with >>>, which represent Python expressions. It then executes these expressions and compares their results with the expected output provided in the docstring. If there’s a match, the test passes; otherwise, it fails.
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.
