Suppress print output in unittests

Question

Edit: Please notice I\'m using Python 2.6 (as tagged)

Say I have the following:

class Foo:
    def bar(self):
        print \'bar\'
         


        

Answer 1

You can suppress the output by disabling the sys.stdout and enabling it after your test is done:

import sys
import io
import unittest

class ut_Foo(unittest.TestCase):
    def test_bar(self):

        #You suppress here:
        suppress_text = io.StringIO()
        sys.stdout = suppress_text 
        
        obj = Foo()
        res = obj.bar()
        self.assertEqual(res, 7)
        
        #You release here:
        sys.stdout = sys.__stdout__
