Python/Django测试运行器导入错误

Question

因此,在初始提交之前启动项目而不是正确设置源代码控制的快乐传统中,我已经破坏了我的Django Test Runner.似乎PATH在某处搞砸了,所以这可能不是Django特有的问题.

我可以成功运行django dev服务器并且所有项目功能都可以运行.我在该项目中可能有70个测试曾经工作过,直到某些时候我引入了一些使它们没有的东西.

错误:

======================================================================
ERROR: app.group.tests (unittest.loader.ModuleImportFailure)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/Users/Jamie/.pyenv/versions/3.4.1/lib/python3.4/unittest/case.py", line 58, in testPartExecutor

检查标准:

没有什么可以搞乱PATH,我已经进入了我无法部署的许多未经测试的功能(以及即将发布的日期)的阶段.有任何想法吗？

因此,在挖掘之后,事实证明Django Test Runner有一个众所周知的警告.如果根项目文件夹中有dunder-init,则会出现此问题.罪魁祸首是下面的第一个文件:

jamiestrauss@jamies-air-2:~/projects/app$ tree
.
??? __init__.py
??? app
?   ??? __init__.py
?   ??? celery.py
?   ??? settings.py
?   ??? urls.py
?   ??? wsgi.py
??? client
?   ??? __init__.py
?   ??? admin.py
?   ??? api.py
?   ??? migrations

当然,存在Shebang!in manage.py,再加上dunder-init意味着整个应用程序作为模块导入,这会混淆内部引用.

tl; dr - 如果发生这种情况,请删除目录__init__.py中的根/project/目录.
