Using Pycharm, I get some different results, then running commands from the terminal. I noticed that after I updated my view, I got a "Apps aren't loaded yet" exception ONLY when running the test from the IDE.
If I run the test via terminal "python3 manage.py test", there is no issue.
IDE runs tests no problem with this view file
def wine_data(request):
return HttpResponse("<html><title>Wine Data</title></html>")
If I change the view file to this:
def wine_data(request):
return render(request, 'wine_data.html')
I get this error (only when ran from IDE)

Any Ideas?

Django belongs to "Frameworks (Full Stack)" category of the tech stack, while PyCharm can be primarily classified under "Integrated Development Environment".
The best base class for most tests is django. test. TestCase. This test class creates a clean database before its tests are run, and runs every test function in its own transaction. The class also owns a test Client that you can use to simulate a user interacting with the code at the view level.
This seems like a Virtual Environment loading error. Have you applied the correct Virtual Environment to your testing env? Check this article and try running it again. http://exponential.io/blog/2015/02/10/configure-pycharm-to-use-virtualenv/
Also on another note, if you're testig for correct template loading or GET requests feel free look at my tutorial.

This worked for me:
Run the test (it fails with the error)
Click the dropdown next to the test name and select 'Edit configurations'
Click on the test name in the left hand panel of the 'Run/Debug configurations' dialog.
Click the minus sign to delete the test. Click OK
Now re-run the test and it passes for me.
My hunch is that dodgy test config gets cached under .idea/ and explicitly deleting the test removes or updates it.
Another workaround is to manually create a Django test:
Edit Configurations
Add new configuration (click the '+' button)
Select 'Django Tests'
Under 'Target', enter the path to the test module (e.g. 'your_app.your_module.tests')
Click OK, and you should be able to run this configuration.

Do you have the correct "Working directory" values and "Target" for your tests?
I faced similar issues with Behave tests...
