I was trying to write a Django unit test for a method that performs some logic and then sends out several emails by calling the "send_email()" method. For the testing purposes, I wanted to replace the original "send_email()" method with "mock_send_email()". This would have been straightforward, if not for the fact that "send_email()" was not implemented in the tested module itself but in another module imported by it.
Here is what finally worked.
emailutils.send_email = mock_send_email # replace the method
reload(testedmodule) # reload the module
from testedmodule import testedmethod # import again
testedmethod() # run the method
Hope this helps.
