     dividend = 15
     divisor = 3
     expected_result = 5.0
     self.assertEqual(calculate(dividend, divisor), expected_result)

示例#2

 def test_zero_value(self):
     dividend = 0
     divisor = 3
     expected_result = 0.0
     self.assertEqual(calculate(dividend, divisor), expected_result)

示例#3

 def test_error_for_zero_devision(self):
     with self.assertRaises(ValueError):
         calculate(5, 0)

示例#4
