python - How to mock out a function that's returned from getattr? -


i have class like:

class myclass(object):     def __init__(self, delegate_to):         self._delegate_to = delegate_to      def __getattr__(self, item):         return getattr(self._delegate_to, item)

but when try like:

my_mock = self.mox.createmock(myclass) my_mock.f().andreturn(none)

mox errors with:

unknownmethodcallerror: method called not member of object: f

how mock out delegated calls?

hacky, try:

class mymock(myclass):     def f():         pass

then in test:

my_mock = self.mox.createmock(mymock) my_mock.f().andreturn(none)
