Mock Python's built in print function

Question

I\'ve tried

from mock import Mock
import __builtin__

__builtin__.print = Mock()

But that raises a syntax error. I\'ve also tried patching

Answer 1

My version.

In the tested program(ex: pp.py):

from __future__ import print_function

def my_func():
    print('hello')

In the test program:

def test_print(self):
    from pp import my_func
    from mock import call
    with mock.patch('__builtin__.print') as mock_print:
       my_func()
       mock_print.assert_has_calls(
            [
                call('hello')
            ]
        )
