I have a Django TestCase, all of whose tests I'd like to run for two different sets of data (in this case, the Bike object whose colour can be red or blue).
Whether that's through loading different fixtures, or the same fixtures and manipulating the colour, I have no preference.
See below example:
class TestBike(TestCase):
fixtures = [
"testfiles/data/blue_bike.json",
]
def setUp(self, *args, **kwargs):
self.bike = Bike.objects.get(color="blue")
run_expensive_commands(self.bike)
def test_bike_1(self):
# one of many tests
def test_bike_2(self):
# second of many tests
One way I considered was using the parameterized package, but then I'd have to parameterize each test, and call a prepare() function from each test. Sounds like a whole lot of redundancy.
Another is to multiple-inherit the test with different fixtures. Also a bit too verbose for my liking.
Did you consider to parameterize on class level, i.e. via class attribute?
class TestBikeBase:
COLOR = "" # Override in derived class.
def setUp(self, *args, **kwargs):
self.bike = Bike.objects.get(color=self.COLOR)
run_expensive_commands(self.bike)
def test_bike_1(self):
# one of many tests
def test_bike_2(self):
# second of many tests
class TestRedBike(TestBikeBase, TestCase):
COLOR = "red"
class TestBlueBike(TestBikeBase, TestCase):
COLOR = "blue"
