ByteSized: Testing your Python code

This last episode of ByteSized RSE before the end of 2022 is about testing your Python code.
Testing is an essential part of software development, and a lot of what we cover in this episode applies to any programming and scripting language. 

For Python, the two big frameworks being used are unittest and PyTest. Unittest is built into Python, whereas PyTest is a module you would need to install extra.

• https://docs.python.org/3/library/unittest.html the built in unit testing framework of Python
  • https://docs.python.org/3/library/unittest.mock.html mock testing in the unittest framework
  • https://docs.python.org/3/library/unittest.html#class-and-module-fixtures fixtures for classes and modules
• https://docs.pytest.org/en/7.2.x/ the popular PyTest framework
  • Mocking can be done with monkeypatch in PyTest https://docs.pytest.org/en/7.1.x/how-to/monkeypatch.html#
  • Fixtures in PyTest: https://docs.pytest.org/en/7.2.x/reference/fixtures.html
