python unittest where does the "X tests run" number come from?

def Tests(unittest.TestCase):

     def test_one(self):
          self.assertEqual(a,1)

     def test_two(self):
          self.assertEqual(b,2)
          assert c == 3
          assert d == 4

     def test_three(self):
          self.assertEqual(e,5)
          assert f ==6

I am getting 2 tests run whereas clearly I have three test functions and 6 asserts. Are my asserts not getting tested?
