Parametrized lazy fixture - incompatibility with pytest-lazy-fixture

[mikicz]

Hello, I came across a incompatibility with pytest-lazy-fixture when using lazy fixtures with parametrized fixtures.

If you take this example with pytest-lazy-fixture:

import pytest

@pytest.fixture(params=["a", "b"])
def some_fixture_a(request):
    return request.param

@pytest.fixture(params=["c", "d"])
def some_fixture_b(request):
    return request.param

@pytest.mark.parametrize(
    "some_fixture", [pytest.lazy_fixture("some_fixture_a"), pytest.lazy_fixture("some_fixture_b")]
)
def test_with_multiple_fixtures(some_fixture):
    pass

It behaves as I would expect, runs the test 4 times:

test_pytest_lazy_fixture.py::test_with_multiple_fixtures[some_fixture_a-a] PASSED           [ 25%]
test_pytest_lazy_fixture.py::test_with_multiple_fixtures[some_fixture_a-b] PASSED           [ 50%]
test_pytest_lazy_fixture.py::test_with_multiple_fixtures[some_fixture_b-c] PASSED           [ 75%]
test_pytest_lazy_fixture.py::test_with_multiple_fixtures[some_fixture_b-d] PASSED          [100%]

However, when you migrate to pytest-lazy-fixtures, this stops working:

import pytest

@pytest.fixture(params=["a", "b"])
def some_fixture_a(request):
    return request.param

@pytest.fixture(params=["c", "d"])
def some_fixture_b(request):
    return request.param

@pytest.mark.parametrize(
    "some_fixture", [pytest.lazy_fixtures("some_fixture_a"), pytest.lazy_fixtures("some_fixture_b")]
)
def test_with_multiple_fixtures(some_fixture):
    pass

The output is:

test_pytest_lazy_fixtures.py::test_with_multiple_fixtures[some_fixture_a] ERROR               [ 50%]
test_pytest_lazy_fixtures.py::test_with_multiple_fixtures[some_fixture_b] ERROR               [100%]

Hello! What version are you using? I've tried 1.1.0 and your test has successfully passed

[mikicz]

Huh! I can't replicate anymore, so closing.

[yugokato]

@dev-petrov I can still reproduce the issue in v1.1.0. The only change I made in the above example code is to use lf from pytest_lazy_fixtures instead of pytest.lazy_fixtures due to #21

pytest==7.4.4
pytest-lazy-fixtures==1.1.0

UPDATE: Looks like the issue happens with the pytest version I'm using. Just tried the same code with pytest 8.3.1 and it worked fine.
Would you take a look?

[dev-petrov]

Try v1.1.1
