Suppose I have this TestCase class.

pass
The unittest docs says:
Each instance of the TestCase will only be used to run a single test
method, so a new fixture is created for each test.
Does this mean that the setUp() method, which is called to prepare the test
fixture, get called for test_A, test_B and test_C?
That's easy enough to find out:
def setUp(self):
print("calling setUp")
...
See how many times "calling setUp" is printed.
In this case is there a
way to force just one setUp() call?
I don't know if this is the best way, but the first way that comes to
mind is this:
class C(TestCase):
initialised = False
def setUp(self):
if self.initialised:
return
# Make sure you save the flag on the class, not the instance!
self.__class__.initialised = True
...
