Using py.test is great and the support for test fixtures is pretty awesome. However, in order to share your fixtures across your entire module, py.test suggests you define all your fixtures within one single
conftest.py file. This is impractical if you have a large quantity of fixtures -- for better organization and readibility, you would much rather define your fixtures across multiple, well-named files. But how do you do that? ...No one on the internet seemed to know.
Turns out, however, you can define fixtures in individual files like this:
import pytest @pytest.fixture def add(x, y): x + y
Then you can import these fixtures in your
import pytest from fixtures.add import add
...and then you're good to test!
import pytest @pytest.mark.usefixtures("add") def test_adding(add): assert add(2, 3) == 5
Because of the modularity, tests will have to be run with
python -m py.test instead of
