I am not sure I should be able to do this, but I am wondering why not.
Code is below. What I would like to do is create two fixtures, but both are based on the same fixture function. However, the second one is stomping on the first one, as demonstrated below. I would have thought I would get First is None, but instead get Not First is None
Code:
import pytest
def generate_params(request):
"""Simple param reflection for pytest.fixtures"""
return request.param
params = pytest.fixture(
scope='function',
params=['First']
)(generate_params)
not_params = pytest.fixture(
scope='function',
params=['Not First']
)(generate_params)
def test_me(params):
assert params is None
