Debugging other people's code, the diary.
So I made code change to this open source project, but don't know how to write the test.
Surely there's already an existing test that touched this code?
Where are those tests?
I know, just use the measurement context from coverage py. Popular open source project like this, surely they use coverage, right?
Looks at codebase.
No coverage.py dependency.

ok... just add 1/0 here then and see which tests break.
3 new failed tests.
Aah, there you are.
