Unittest tests order

Question

How do I be sure of the unittest methods order? Is the alphabetical or numeric prefixes the proper way?

class TestFoo(TestCase):
    def test_1(self):
               


        

Answer 1

Contrary to what was said here: - tests have to run in isolation (order must not matters for that) AND - ordering them is important because they describe what the system do and how the developper implements it.

IOW, each test brings you informations of the system and the developper logic.

So if these informations are not ordered that can make your code difficult to understand.
