Python Testing with pytest

Testing a Package

We’ll use the sample project, Tasks, as discussed in ​The Tasks Project​, to see how to write test functions for a Python package. Tasks is a Python package that includes a command-line tool of the same name, tasks.

Appendix 4, ​Packaging and Distributing Python Projects​ includes an explanation of how to distribute your projects locally within a small team or globally through PyPI, so I won’t go into detail of how to do that here; however, let’s take a quick look at what’s in the Tasks project and how the different files fit into the story of testing this project.

Following is the file structure for the Tasks project:

tasks_proj/
├── CHANGELOG.rst
├── LICENSE
├── MANIFEST.in
├── README.rst
├── setup.py
├── src
