Answer 1

I needed to prevent certain signals from firing during unittests so I made a decorator based on qris's response:

from django.db.models import signals

def prevent_signal(signal_name, signal_fn, sender):
    def wrap(fn):
        def wrapped_fn(*args, **kwargs):
            signal = getattr(signals, signal_name)
            signal.disconnect(signal_fn, sender)
            fn(*args, **kwargs)
            signal.connect(signal_fn, sender)
        return wrapped_fn
    return wrap

Using it is simple:

@prevent_signal('post_save', my_signal, SenderClass)
def test_something_without_signal(self):
    # the signal will not fire inside this test
