Mutually exclusive fixtures

[vallsv]

Hi,

Found out this question was few time asked, but maybe there is another approach now.

I have a resource which have to be reused as much as possible on the tests, but my tests needs 2 different setup of it.

It sounds like the easiest way to modelize that is to have 2 different fixtures which are mutually exclusive.

I have struggled a lot with package scope, session scope, constraints in different ways, without finding something really nice.

For now i use the following solution, which enforce a sequence for each setup of the resource.

@pytest.fixture(scope="session", params=["resource_setup1", "resource_setup2"])
def each_resource_setup(request):
    with my_resource_setup(request.param) as r:
        r.param = request.param
        yield r

@pytest.fixture(scope="session")
def resource_with_setup1(each_resource_setup):
    if each_resource_setup.resource_param != "resource_setup1":
        pytest.skip()
    yield each_resource_setup

@pytest.fixture(scope="session")
def resource_with_setup2(each_resource_setup):
    if each_resource_setup.resource_param != "resource_setup2":
        pytest.skip()
    yield each_resource_setup

Half of the tests are still marked as skipped, but this ensure to me that the sequence SETUP/TEARDOWN is properly executed to the resource.

Any idea if there is a better approach?
