Question

我正在尝试在我的django应用程序上运行单元测试但是我遇到了以下错误。运行应用程序很好。我正在使用pycharm 3.0。

C:\Users\user\my-project-env\Scripts\python.exe "K:\Program Files (x86)\JetBrains\PyCharm 3.0\helpers\pycharm\utrunner.py" C:/Users/user/PycharmProjects/my-project/my_app/ true

Answer 1

您使用的是Djangos单元测试库，还是使用蟒蛇？ Django需要设置一些东西才能加载，例如模型，即它需要设置，如堆栈跟踪所示。

如果您按照文档https://docs.djangoproject.com/en/1.5/topics/testing/overview/进行操作，您会发现Django已经为正常的单元测试功能做了一些插件。使用它并调用Django单元测试将为您运行它。将其作为Django单元测试运行意味着使用

运行它们

$ ./manage.py test

或者因为你使用pycharm，你可以选择将单元测试作为Django单元测试来运行，PyCharm会在你调用测试时问你。

Answer 2

看看Traceback：

django.core.exceptions.ImproperlyConfigured: 请求设置DATABASES，但未配置设置。您必须先定义环境变量DJANGO_SETTINGS_MODULE或在访问设置前调用settings.configure（）。

Answer 3

更多是由于Pycharm中的设置问题，请看这个问题。 Pycharm error: Improperly configured

运行单元测试时，Django无法找到设置文件
