@pytest.mark.usefixtures("appsettings")
class TestUtilsTemplate(object):
    def setup_method(self, method):
        self.request = testing.DummyRequest()
        self.config = testing.setUp(settings=self.appsettings, request=self.request)

    def teardown_method(self, method):
        testing.tearDown()

this might work easier (you may need to make the appsettings fixture function return a value rather than setting a class attribute:

class TestUtilsTemplate(object):
@pytest.fixture(autouse=True)
def setup(self, appsettings, request):
self.request = testing.DummyRequest()
self.config = testing.setUp(settings=appsettings, request=self.request)
request.addfinalizer(testding.tearDown)
