我正在打包一个我想重用的Django应用程序（希望可以被其他人使用），我想创建一个测试用例，当app在不同的上下文中使用时，它会模仿定义子类。 / p>
我发现this solution在Python测试用例中做了类似的事情，但是，我的Django测试用例出现以下错误。
RuntimeError: Model class tests.test_unit_health.Heart doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.
下面类似于我设置的产生此错误的内容：
models.py
from django.db import models
class HealthTest(models.Model):
# some attributes...
# some methods...
def get_score(self, **kwargs):
score = self.score(**kwargs)
# more logic
test_unit_health.py
from django.test import TestCase
from health.models import HealthTest
class HealthTestCase(TestCase):
def setUp(self):
class Heart(HealthTest):
def score(self, heartrate):
if heartrate > 90:
return 2
else:
return 1
完整错误如下所示：
======================================================================
ERROR: tests.test_unit_health (unittest.loader.ModuleImportFailure)
----------------------------------------------------------------------
ImportError: Failed to import test module: tests.test_unit_health

非常感谢任何有助于此工作的帮助。谢谢！
