Python unittest with multiple test data's

Python sample script for unitest with multiple test data's

import unittest
from my_math import product

data = [(2,3,6),(3,3,9),(4,3.5,11)]

class Test(unittest.TestCase):
    """Tests for Product"""
    def test_product(self):
        try:
            for a,b,expected in data:
                self.failUnlessEqual(product(a,b),expected,"Product Testcase")
                print "Expected is ",expected
        except AssertionError:
            print "Assertion Error, Check the Values"


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


my_math.py file contains:

#__author__ = 'valli'
def product(a,b):
    return a*b
