no example standard run Django tests with `TestCase`

[ArtemIsmagilov]

I want to run tests the standard Django way. But I don't understand how.

mutmut 3.x only supports pytest. But pytest should be able to run unittest test, so first get that working. (Although, as a Django developer myself, I would also recommend switching to pytest because unittest-style tests are a pain in the ass and not very pythonic :P)
