1.    If you don't unit test your bits and pieces AND you call them in
your views they might pass with wrong values. Subtle errors can creep in
if your views are tested too coarsely.

2.    The more fine-grained the unit tests the easier it is to refactor
your view code.

3.    Do you use Coverage? You will see all the Django code is tested.
Only your own code to test

I do integration testing at a high level as well as down low. Really
does wonders for refactoring confidence.

YMMV
