Python Testing with Unittest

This repository is designed to illustrate how to perform unit testing in Python using the unittest tool. The project is structured in evolutionary steps, represented in different Git branches: step__1, step__2, ..., up to step__14. Each branch shows a step toward the full implementation of tests, from the initial setup to the integration of tests and the generation of coverage reports.

Project Structure

  • Branches: Each branch contains a specific phase of the unit testing development. You can follow the progress of the implementation step by step starting from step__1 to step__14.
  • Unit Tests: The tests are organized within the src_tests folder.
  • Test Coverage: The Coverage tool is used to measure the test coverage and generate detailed reports.

Commands Used

Here are the main commands used in this project to run the tests and generate coverage reports:

  1. Run unit tests:

    python3.12 -m unittest discover -v -s src_tests

  2. Run tests from a specific file::

    PYTHONPATH=. python3.12 src_tests/suites.py

  3. Generate coverage report::

    coverage run --source src -m unittest
coverage report  
coverage html

  4. Run unit tests:

    coverage run --source ./src_tests -m unittest

Purpose

The purpose of this project is to teach and demonstrate how to structure a testing project in Python, how to use unittest to test functions, and how to achieve full test coverage using the coverage tool. By following the different branches, developers can see how the project is structured and progresses, continually improving the tests and ensuring their quality.

Conclusion

This project is a practical example of how to structure a testing project in Python, and how to use unittest to test functions.
