测试步骤
1. 导入unittest模块
import unittest
2. 编写测试的类继承unittest.TestCase
class Tester(unittest.TestCase)
3. 编写测试的方法必须以test开头
def test_add(self)
def test_sub(self)
Method | Checks that | New in |
---|---|---|
assertEqual(a, b) | a == b | |
assertNotEqual(a, b) | a != b | |
assertTrue(x) | bool(x) is True | |
assertFalse(x) | bool(x) is False | |
assertIs(a, b) | a is b | 2.7 |
assertIsNot(a, b) | a is not b | 2.7 |
assertIsNone(x) | x is None | 2.7 |
assertIsNotNone(x) | x is not None | 2.7 |
assertIn(a, b) | a in b | 2.7 |
assertNotIn(a, b) | a not in b | 2.7 |
assertIsInstance(a, b) | isinstance(a, b) | 2.7 |
assertNotIsInstance(a, b) | not isinstance(a, b) | 2.7 |
5.调用unittest.main()方法运行所有以test开头的方法
if __name__ == ‘__main__‘:
unittest.main()
实例如下
被测试类
#!/usr/bin/python #coding=utf-8 class Computer(object): @staticmethod def add(a, b): return a + b; @staticmethod def sub(a, b): return a - b;<strong> </strong>
测试类
#!/usr/bin/python #coding=utf-8 import unittest from Testee import Computer class Tester(unittest.TestCase): def test_add(self): self.assertEqual(Computer.add(2, 3), 5, "test add function") def test_sub(self): self.assertEqual(Computer.sub(5, 1), 4, "test sub function") if __name__ == '__main__': unittest.main()
?运行结果:
