unittest测试框架_2_断言设置

Posted 2021-12-30 ninijiang

在执行测试用例的过程中，用例是否执行通过，需要判断测试得到的实际结果与预期结果是否相等决定的。以下是一些常用的断言操作：

assertEqual(a,b,msg=None) 判断a是否等于b，等于则断言通过

assertNotEqual(a,b,msg=None)判断a是否不等于b，等于则断言通过

assertTrue(a,msg=None) 判断a是否为True，等于则断言通过

assertFalse(a,msg=None)判断a是否为False，等于则断言通过

assertIn(a,b,msg=None) 判断 b 是否包含 a，等于则断言通过

assertNotIn(a,b,msg=None)判断 b 是否不包含 a，等于则断言通过

assertIs(a,b,msg=None) 判断 b 是否是 a，等于则断言通过

assertIsNot(a,b,msg=None) 判断 b 是否不是 a，等于则断言通过

assertIsNone(a,msg=None)判断a是否为None，等于则断言通过

assertIsNotNone(a,b,msg=None)判断a是否不为None，等于则断言通过
