V2: Align case functions with parametrize_plus/fixture_ref experience

[smarie]

Now that parametrize_plus fully supports fixture_ref and pytest.param, we should be able to fully uniformize the experience provided in "case functions" with the experience of parametrize_plus:

• passing ids and marks should be similar/aligned.

  • For single case functions: as of now we have a @case_name decorator to customize the id, and on the other hand case functions can be decorated with @pytest.mark. Should we simply rename @case_name into @case_id for consistency with pytest ? Or provide a function similar to pytest.param to be able to customize both id and mark at the same time ? (@case_marks(id=..., marks=...)). EDIT better: provide a simple @case decorator to customize name/id and marks

  • For case generators, there is probably no need any more to have a different way to generate their names than the ids parameter from pytest. Or if so, it should be an additional helper, not an alternate engine.

• what about the lru_cache mechanism then ?

• a case function should be able to require a fixture, see Allow case functions to require a fixture #56

etc.

See #96: the user-friendly decorators should be kept ! So the changes should be on the internal side but should not make it more complex for users (do not force users to use pytest.mark.parametrize)

However power users should be able to use the pytest API directly on case functions (mark.parametrize)
