Multiple copies of a pytest fixture
django, pytest, python, testing
Solution
My approach would probably to create a fixture which can generate your objects:
@pytest.fixture
def thing(request, db):
class ThingFactory(object):
def get(self):
thing = MyModel.objects.create()
request.addfinalizer(thing.delete)
return thing
return ThingFactory()
def test_thing(thing):
thing1 = thing.get()
thing2 = thing.get()
Obviously you can make `.get()` take an argument etc.
(PS: Also note there's no need for the lambda in the finalizer)
Problem
Let's say I have a simple fixture like the following (using pytest-django, but it applies to pytest as well): ``` @pytest.fixture def my_thing(request, db): thing = MyModel.objects.create() request.addfinalizer(lambda: thing.delete()) return thing ``` This works great when my tests need a single instance of MyModel. But what about if I need two (or three or four)? I want each instance to be distinct, but to be set up in the same way. I could copy/paste the code and rename the fixture function, but that seems inelegant. Similarly, I have tried: ``` @pytest.fixture def my_thing_1(my_thing): return my_thing @pytest.fixture def my_thing_2(my_thing): return my_thing ``` However, each of these appears to return the same instance of MyModel. Is there a way to do what I want using pytest's built-in functionality? Alternately, I could move the setup/teardown of my fixture out into helper functions so I'm not duplicating too much code. Or am I going about this whole thing the wrong way?
