此外,mock 模块提供了一个叫做patch() 的装饰器,它负责在测试的上下文中修补类和模块级别的特性,并提供了一个用于产生唯一实例的哨兵。 示例代码: 代码语言:python 代码运行次数:0 运行 AI代码解释 fromunittest.mockimportpatch@patch('sample_module.sample_object')deftest_function(mock_object):print(mock_objec...

unittest 官网文档的关于 patcher 的第一句话很重要: The patch decorators are used for patching objects only within the scope of the function they decorate. They automatically handle the unpatching for you, even if exceptions are raised. All of these functions can also be used in with statements ...
