MAINT: Add more pytest idiom to parser tests by gfyoung · Pull Request #23712 · pandas-dev/pandas (original) (raw)

@jreback @jbrockmendel : Here is the plan:

• c_parser_only.py is now separate from test_parsers.py, so you can just run pytest test_c_parser_only.py (the fixtures get automatically injected per the newly created conftest.py). The new format of those tests is 100% functional (no classes), which is more pytest-idiomatic.
• If this format looks good, I will convert all other files (e.g. header.py, comment.py, mangle_dupe_cols.py similarly in subsequent PR's (we will be in this weird intermediate state with test_parsers.py and conftest.py co-existing).

Once that is done, we no longer need test_parsers.py. All tests will be nice and modular and not all clumped into one giant test class as they are currently.

Hopefully that clears things up?
