How to run all tests with python manage.py test command in django

Question

I am working on a django project in which I have multiple apps. Every app has a tests directory which has test for whole project. My directory structure is as follow.

Project
      App_1
           tests
               __init__.py
               tests_views.py
      App_2
           tests
               __init__.py
               tests_views.py
      settings.py
      manage.py

I can run tests like this

python manage.py test App_1.tests

which run all tests in App_1/tests/test_views.py. But I have to do this for all app in my project. I want a single command which run all tests inside all apps in my project. I tried by running

python manage.py test

but I got following error

ImportError: 'tests' module incorrectly imported from '/vagrant/code/project/App_1/tests'. Expected '/vagrant/code/project/App_1'. Is this module globally installed?

Can any one tells me how I can all tests in my app with a single command?

Answer 1

Running python manage.py test is the right way to run all the tests in your projects at once, your error is caused by something else.

Is there a problem with the folder structure of your tests? To use the default unittest functionality they should be stored like this:

myproject/
   myapp/
       tests/
           __init__.py
           test_models.py
           test_views.py

I think your problem is caused because you may have a tests folder within your tests folder, which is confusing unittest. Also make sure you have __init__.py in your folders so python can see the files inside. Have a look here for the Django testing documentation.

Answer 2

Іf you are creating a test package in your application, delete default test.py file in your app. This will solve your problem.

Answer 3

I had a similar problem. My file structure looked like this

project/
    apps/
        app_1/
            test/
                __init__.py
                test_views.py

        app_2/
             test/
                __init__.py
                test_models.py
    manage.py

And for me helps to set folder (not an app from installed apps). All tests runs by command python ./manage.py test apps/ attention to the trailing slash

tests for app_1 runs by command python ./manage.py test app_1
