All ok

Could it be that django/utils contain a folder unittest that is imported instead of Python unit testing framework ?

[bfroehle]

Yes, this is an unavoidable artifact of Python's import mechanism. The unittest module in your current directory is shadowing the system unittest module. There's nothing we can do here, unfortunately.

[Carreau]

Ah, true, note for myself, you do not need to clone a github repo to browse it..
