It's not possible to have extra arguments to unittest functions. See the note at the end of https://docs.pytest.org/en/latest/unittest.html .

Hello, why has this issue been closed? It would be a useful feature.

It's not supportable by unittest, so it's not added

Unittest is only supported, not extended
