parametized unittest

[CraftyTech]

hello all,

I'm trying parametize my unittest so that I can re-use over and over, perhaps in a for loop. Consider the following:

'''
import unittest

class TestCalc(unittest.TestCase):
def testAdd(self):
self.assertEqual(7, 7, "Didn't add up")

if __name__=="__main__":
unittest.main()

'''


Simple and straight forward, but I'm trying to get to a place where I can run it this way:

import unittest

class TestCalc(unittest.TestCase):
def testAdd(self,var):
self.assertEqual(var, 7, "Didn't add up")

if __name__=="__main__":
unittest.main(testAdd(7))

is this possible? I'm finding it hard to use unittest in a for loop. Perhaps something like:

for val in range(25):
self.assertEqual(val,5,"not equal)

The loop will break after the first failure. Anyone have a good approach for this? please advise.

cheers,

If Python 3.4 is an option, you can stick to the standard library and
use subtests [1].

If Python 3.4 is an option, you can stick to the standard library and
use subtests [1].

Or, as yet another alternative, if you use nose, you can write test
generators.

Thank you all for the feedback. I now have what I need. Cheers
