            description = "Learn to write regular expressions in Pyhton"
        )

        now = timezone.now()
        self.assertLess(course.created_at, now)

class StepModelTests(TestCase):
    def setUp(self):
        self.course = Course.objects.create(

        self.assertIn(step, self.course.step_set.all())
