Day 3 v2: GitHub Action CI for wsblib Python

#python #opensource #beginners #programming

After the failure to create GitHub configuration for farmworld
I did not know if I should call it a day or try to find something else where I manage to set up GitHub Actions. I went back to PyDigger and found the wsblib Python package where the name stands for Web Server Base Library.

It had some tests in the tests/ folder.

After looking at the test files I saw that they are using BuPyTest.
I have not hear about it. I saw that both files were prepared to be executed directly using the following:

if __name__ == '__main__':
    bupytest.this()

so I went on running them as python tests/test_server.py.

Later, when I went and looked at the documentation of BuPyTest and saw that it can be also used as a command-line tool.

Stages

First I only configured the CI to run on Ubuntu using Python 3.11.

Then I extended it to run the tests on all 3 operating systems and 3 different versions of Python. That's when I found out that one of the test files consistently fails on Windows and OSX. So I configured the CI that on of the tests files will always run and the other one only when the operating system is Ubuntu Linux.

Finally I switched from running the tests with python to running them using bupytest.
