Separate test code from test cases in pytest

Did you ever think that most of your test functions were actually the same test code, but with different data inputs and expected results/exceptions? - pytest-cases leverages pytest and its great @pytest.mark.parametrize decorator, so that you can separate your test cases from your test functions. - In addition, pytest-cases provides several useful goodies to empower pytest. In particular it improves the fixture mechanism to support "fixture unions". This is a major change in the internal pytest engine, unlocking many possibilities such as using fixture references as parameter values in a test function. See here. pytest-cases is fully compliant with pytest-harvest so you can easily monitor the execution times and created artifacts. With it, it becomes very easy to create a complete data science benchmark, for example comparing various models on various datasets.
