Can't use given fixture in another fixture

[Gaasmann]

Hello,

I'm trying to use an autouse fixture to do some cleanup after a test. I'm defining a fixture depending of the given step but that doesn't seem to work. I'm not sure why or how to fix that or if this is a bug.

@pytest.fixture(autouse=True)

    print(the_fixture)
    yield
    print("cleanup stuff depending on the_fixture")


@when("I check the fixture")

    assert the_fixture == "a useless fixture"


@then("nothing")

    pass

If you look at the list of available fixtures, you'll see "pytestbdd_given_the given step defines a fixture", I'm not sure how to use/reference that one or if it would work like the_fixture but it seems pytest is somehow aware of the given step.

Thanks

Step defined fixture is injected after module/conftest/plugin fixtures. Just one reason to use target_fixture is to modify an already defined environment for the test. You could define "the_fixture" as the usual pytest fixture and modify it from the given step.
