为了实现这一目的,unittest.mock模块提供了一系列的断言方法,例如: assert_called_once_with:验证Mock对象被调用且仅被调用一次,并且参数与预期相符。 assert_called_with:验证Mock对象被调用,并且参数与预期相符。 assert_called_once:验证Mock对象被调用且仅被调用一次。 通过这些断言方法,我们可以轻松地验证Mock对象的...
tc = TestClass()# 使用MagicMock创建并替换原来的func方法,并指定其被调用时的返回值tc.func = MagicMock(return_value='666')print(tc.func(2,3))# 判断func是否按照指定的方式被调用,如果没有,# 比如这里指定assert_called_with(4, 5),就会抛出异常,# 因为之前使用的是tc.func(2, 3)来进行调用的print...
m.some_method(*args, **kwargs) assert m.some_method is mock_method m.some_method.assert_called_with(*args, **kwargs) (3)怎么 mock 一个类? 有时候须要模拟一个函数或者类的行为。包含它全部的属性和方法,假设手动去一个个加入,实在低效并且easy出错。mock提供了autospec的功能。依据提供的模板类生...

All these test cases use the assert statement. Most of them are written using the assertion formats that you learned before. They all showcase how you’d write real-world test cases to check different pieces of your code with pytest. Now, why does pytest favor plain assert statements in te...
assertIsNotNone(x,[msg='测试失败时打印的信息']): 断言x是否None,不是None则测试用例通过。assertIn(a,b,[msg='测试失败时打印的信息']): 断言a是否在b中,在b中则测试用例通过。assertNotIn(a,b,[msg='测试失败时打印的信息']): 断言a是否在b中,不在b中则测试用例通过。assertIsInstance(a,b,[...
assert_called_once_with(mock_form.save.return_value) # We mock out the redirect function, this time at the method level. patch decorators are applied innermost first, so the new mock is injected to our method as before the mockNewListForm. We specify we’re testing the case where the...
通过called, called_count,assert_called,...这几个api了解打桩方法是否被访问,访问次数等。 通过side_effect设置方法的副作用,抛异常测试异常分支。(注意它和return_value的区别) 通过call_args等方法与Call类对被打桩方法的参数进行判断 愿天下没有难打的桩 对一些处理起来比较麻烦的打桩场景进行介绍 with语句 如果...
