unittest单元测试框架学习之--断言

断言

断言内容是自动化脚本的重要内容，正确设置断言以后才能帮助我们判断测试用例执行结果。

断言方法

• assertEqual(a, b)    判断a==b
• assertNotEqual(a, b) 判断a！=b
• assertTrue(x) bool(x)  is True
• assertFalse(x) bool(x)  is False
• assertIs(a, b)    a is b 判断a是不是b
• assertIsNot(a, b)  a is not b
• assertIsNone(x)   x is None
• assertIsNotNone(x)  x is not None
• assertIn(a, b)   a in b
• assertNotIn(a, b)   a not in b
• assertIsInstance(a, b)  isinstance(a, b)  判断是否为实例
• assertNotIsInstance(a, b)  not isinstance(a, b)
