I am looking into the unittest package, and I'm not sure of the proper way to structure my test cases when writing a lot of them for the same method. Say I have a fact function which calculates the factorial of a number; would this testing file be OK?

import unittest

class functions_tester(unittest.TestCase):
    def test_fact_1(self):
        self.assertEqual(1, fact(1))
    def test_fact_2(self):
        self.assertEqual(2, fact(2))
    def test_fact_3(self):
        self.assertEqual(6, fact(3))
    def test_fact_4(self):
        self.assertEqual(24, fact(4))
    def test_fact_5(self):
        self.assertFalse(1==fact(5))
    def test_fact_6(self):
        self.assertRaises(RuntimeError, fact, -1)
        #fact(-1)

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

It seems sloppy to have so many test methods for one method. I'd like to just have one testing method and put a ton of basic test cases (ie 4! ==24, 3!==6, 5!==120, and so on), but unittest doesn't let you do that.

What is the best way to structure a testing file in this scenario?

Thanks in advance for the help.
