AttributeError:'module'对象没有属性'tests'

Question

我正在运行此命令:

python manage.py test project.apps.app1.tests

它会导致此错误:

AttributeError:'module'对象没有属性'tests'

下面是我的目录结构.我还在我安装的应用配置中添加了app1.

Answer 1

我终于想出了另一个问题.问题是我的测试无法找到导入.

如果您的测试无法导入,看起来您会收到上述错误.这是有道理的,因为测试套件无法导入损坏的测试.至少我认为这是正在发生的事情,因为我在我的测试文件中修复了导入,确定它开始工作了.

要验证您的测试用例,请尝试在python控制台中导入测试用例文件.

例:

from project.apps.app1.tests import *

Answer 2

使用:

./manage.py shell

其次是

import myapp.tests

找到导入错误的性质.

Answer 3

对于我的情况,我需要在我的文件夹中创建一个空的__init__.pyapp/tests

Answer 4

Steve Bradshaw上面的例子适用于导入错误(感谢Steve).

其他类型的错误(例如ValueError)也可能导致

AttributeError: 'module' object has no attribute 'tests'

看看这些错误是什么

./manage.py shell
from myapp.tests import SomeTestCase
t = SomeTestCase()

Answer 5

我和克里斯有同样的错误。我删除了一个旧模型，然后运行tests.py，但另一个文件（views.py）仍在尝试导入已删除的模型。

当我取出现已过时的导入语句时，问题解决了。
