New submission from Claudiu.Popa:
I was surprised that in the following __init__ is actually called once per test
function, although nothing in documentation implied so.
a.py
------
import unittest
class A(unittest.TestCase):
def __init__(self, *args, **kwargs):
print('called only once!')
super().__init__(*args, **kwargs)
def test(self):
self.assertEqual(1, 1)
def test2(self):
self.assertEqual(2, 2)
if __name__ == '__main__':
unittest.main()
$ python a.py
called only once!
called only once!
..
----------------------------------------------------------------------
Ran 2 tests in 0.001s
OK
The attached patch adds a note regarding this behaviour for the TestCase class.
