How to patch a module's internal functions with mock?

Question

By \"internal function\", I mean a function that is called from within the same module it is defined in.

I am using the mock library, specifically the patch decorators,

Answer 1

another option is to explicitly call patch on the function:

mock.patch('function_name')

and to support both running directly or from py.test etc:

mock.patch(__name__ + '.' + 'function_name')
