Question

我正在尝试编写一个名为Dynamic Response的django插件测试（可在GitHub上获得），但我遇到了一些问题。使用模拟我试图模拟某些Django方法，如render_to_response，（我毕竟不打算测试django）但是当我尝试这样做时，我收到一条错误消息，说它无法找到settings.py，它不应该是因为这是一个在其他项目中使用的插件，而不是一个项目本身。我尝试过以下代码：

class ResponseTest (unittest.TestCase):

    @patch('dynamicresponse.response.render_to_response')
    def test_is_testframework_working(self, render_to_response):
        from dynamicresponse.response import SerializeOrRender
        SerializeOrRender()

如上所述，它给出了一条错误消息。 Stubbing HttpResponse，HttpRedirect不会抛出这些错误......

给出以下stacktrace

Response (unittest.loader.ModuleImportFailure) ... ERROR

你不能在没有任何项目（真实或虚拟，无论如何）的情况下测试django应用程序。

模拟Django插件：找不到settings.py
