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):

Note that the order in which the various test cases will be run is determined by sorting the test function names with respect to the built-in ordering for strings.

If you need set order explicitly, use a monolithic test.

class Monolithic(TestCase):
  def step1(self):
      ...

  def step2(self):
      ...

  def steps(self):
    for name in sorted(dir(self)):
      if name.startswith("step"):
        yield name, getattr(self, name) 

  def test_steps(self):
    for name, step in self.steps():
      try:
        step()
      except Exception as e:
        self.fail("{} failed ({}: {})".format(step, type(e), e)
