In https://github.com/pandas-dev/pandas/issues/50378, I found a test which isn't run in CI because its name doesn't start with test (as required by pytest)
I'm sure there's more
To find them, I think we need some AST which checks files in pandas/tests, which:
- have names not starting with test
- aren't decorated (else they might be fixtures)
- aren't used anywhere else inside that file (else they might be helper functions)
