我在名为testDummy.py的文件中有一个最小的测试用例，该文件位于/MyApp/MyApp/（与默认settings.py一起）
from django.test import TestCase
class DummyTests(TestCase):
def setUp(self):
print("Setup")
def tearDown(self):
print("Teardown")
def test_noddy(self):
self.assertEqual(1, 2)
执行manage.py test -v 2时，我得到......

Ran 10 tests in 0.389s
OK
Destroying test database for alias 'default' ('test_myapp')...
然而，它总是运行相同的10个测试（没有一个是我的）。如果我manage.py test -v 2 MyApp，则运行0次测试。
我错过了什么？
