python unittest的使用

1，注意事项，py文件要以test开头，否则不会被执行

2，@classmethod        @classmethod

   def setupClass(self)　def teardownClass(self) ----全局函数，只运行一次

3，unittest断言的使用

方法	检查
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
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)
assertNotIsInstance(a, b)	not isinstance(a,b)
