While playing around with django testing I noticed that Permission table in test database is not empty (like, for example, User and tables of models defined by me) – it has all permissions from the real table.
My questions:
- Is the
Permissiontable the only prepopulated table? (I have trouble inspecting other tables, because db is in-memory) - Where is it prepopulated (I also couldn’t find)? Upon setting up test suit? Or just before executing each test method? Or maybe added to queryset everytime it is requested?
>Solution :
Permissions are created when you run manage.py migrate, there is a signal handler that listens to the post_migrate signal and creates these permissions for every new model.
The ContentType table will also be populated in a similar manner
When you run your tests, your test DB will have your migrations applied to it
