How can I access the return value of a fixture defined via @pytest.mark.usefixtures

[FelixKJose]

I am not able to access the return value of a fixture when it is defined via @pytest.mark.usefixtures.

Eg:
conftest.py:

@pytest.fixture
def test_envs():
    return {"data": ["dev", "staging"]}

Following doesn't work:
test_example_fixture.py

@pytest.mark.usefixtures("test_envs")
class Test:
    def test_fixtures(self):
        print("Fixture values:", self.pytestmark[0]["data"])

def test_fixtures_func(test_envs):
        print("Fixture values:", test_envs["data"])

worked. So you cannot use "@pytest.mark.usefixtures" to add fixtures for all tests in a Test class or module and access the defined fixtures return value in each test?

if you want to use the value of a fixture, take it as a function argument

pytest will not under any circumstance monkeypatch fixtures into other places
