AttributeError: 'module' object has no att

Question

I'm running this command:

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

and it causes this error:

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

Below is my directory structure. I've also added app1 to my installed apps config.

Answer 1

Use:

./manage.py shell

followed by

import myapp.tests

to find the nature of the import error.

Answer 2

I finally figured it out working on another problem. The problem was that my test couldn't find an import.

It looks like you get the above error if your test fails to import. This makes sense because the test suite can't import a broken test. At least I think this is what is going on because I fixed the import within my test file and sure enough it started working.

To validate your test case just try import the test case file in python console.

Example:

from project.apps.app1.tests import *

Answer 3

Steve Bradshaw's example above works for import errors (thanks Steve).

Other type of errors (e.g. ValueError) may also cause

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

to see what these errors are

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

Answer 4

I resolved the error "AttributeError: module 'utils' has no attribute 'name_of_my_function' " by fixing a circular import reference. My files manage.py and utils.py each had an import statement pointing at each other.

Answer 5

Got the same error, but checked all the reasons list here, did not fix my problem.

Finally figure it out that, the reason is that the name of one method that imported but not used yet is not correct. Though it is a stupid error, it happens.

Answer 6

For my case, I need to create an empty __init__.py in my app/tests folder
