    1. COI can't reproduce this. Have done a "startproject" before "startapp" ?

    2. COI can't reproduce this. Have you done a "startproject" before "startapp" ? What is `test_basic_addition`? It's not in your code. Shouldn't you test the specific app (`python3 manage.py test lists`) ?

    3. COyeah I did startproject before startapp, and tried the command you gave me, the same stacktrace comes back except with the error header ERROR: test_bad_maths (lists.tests.SmokeTest) instead, I don't know how that was there, I fixed it now, I have tried uninstalling django, completely making sure there was no other versions on my mac, then reinstalling it and same errors, also tried setting up a virtualenv environment with a fresh django and same stacktrace comes back, im stumped at what it could be, I think it wants some database initialized but it shouldn't need one for a simple test

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
