Question

I am writing a test suite in python 2.6 using the unittest framework, and I want to use asserts in my code. I know that asserts got a complete overhaul and are much nicer in 2.7+ but I am confined to using 2.6 for now.

I am having problems using asserts. I want to be able to use the assertIn(a,b) feature, but alas, that is only in 2.7+. So I realized I must use the assertTrue(x) which is also in 2.6, but that didn’t work. Then, I looked at this document which says that in previous versions assertTrue(x) used to be failUnless(x), so I used that in my code, and still no results.

I get the message:

NameError: global name ‘failUnless’ is not defined

which is the same thing I got for assertIn(a,b) and for assertTrue(x).
So I am totally at a loss for what I should do.

shorter version of my problem:

I want to be able to implement assertIn(a,b) in python 2.6.
Anyone have any solutions to this?

my code:

import unittest

class test_base(unittest.TestCase):
    # some functions that are used by many tests

class test_01(test_base):
    def setUp(self):
        #set up code

    def tearDown(self):
        #tear down code

    def test_01001_something(self):
        #gets a return value of a function
        ret = do_something()

        #here i want to check if foo is in ret
        failUnless("foo" in ret)

edit: Seems I am an idiot. All I needed to do was add self.assert.... and it worked.

Answer 1

import unittest

class MyTest(unittest.TestCase):
    def test_example(self):
        self.assertTrue(x)

This should work, based on the docs for unittest from Python 2.6. Be sure to use it as TestCase.assertTrue().

edit: In your example, set it as self.failUnless("foo" in ret) and it should work.
