Description
pytest-cov is a pytest plugin that helps produce coverage reports using Coverage.py.
In this episode, we'll discuss:
- what Coverage.py is
- why you should measure code coverage on both your source and test code
- what pytest-cov is
- extra features pytest-cov gives you over and above coverage.py
- and generally why using both is awesome

Errata:
- I mentioned that Coverage has the ability to show context (which line is covered by which test) for the past year or so.
- However, that feature was released in Oct 2018. coverage 5.0 alpha
- That's over 6 years. Oops. Sorry Ned.
