parametrize_from_file

Parametrize test functions with values read from config files.

Note that this module itself can be used as an alias for parametrize, e.g.:

import parametrize_from_file

@parametrize_from_file
def test_my_func(given, expected):
    assert my_func(given) == expected

This is the recommended usage if you do not need to import any other names from the module. If you do need to import other names, the recommendation is instead to import the module as pff, e.g.:

import parametrize_from_file as pff

@pff.fixture
def env(request):
    return request.param

@pff.parametrize
def test_my_func(given, expected, env):
    assert my_func(given) == expected
