如果一个测试类的每个测试case都要mock module1.globalMethodOne这个方法,那么可以在class level加上decorator: from unittest import TestCase from module2 import TwoClz @patch("module2.globalMethodOne") class Test1(TestCase): def test_Sth(self, mock_mthd): ... 注意:这里的patch name, 由于在m...
Additionally, mock provides apatch()decorator that handles patching module and class level attributes within the scope of a test, along with sentinel for creating unique objects. See the quick guide for some examples of how to useMock,MagicMockandpatch(). Mock is very easy to use and is desi...
为了能够执行测试,我们使用了unittest.mock.patch()方法作为上下文管理器,把标准输出sys.stdout替换为了StringIO对象,这样发送的标准输出的内容就会被StringIO对象所接收。变量fake_out就是在这一过程中所创建出的模拟对象,该对象能够在with所处的代码块中所使用,来进行一系列的测试检查。当with语句完成时,patch方法能够...

所有新的测试应该使用 unittest 或doctest 模块编写。一些旧的测试是使用“传统”的测试风格编写的,即比较打印出来的输出到``sys.stdout``;这种测试风格被认为是过时的。参见 模块unittest 编写PyUnit 回归测试. doctest --- 文档测试模块 Tests embedded in documentation strings....
unittest.mock 中最常用的功能包括 Mock 类和 patch 装饰器/上下文管理器。 Mock 对象可以用来模拟函数或对象的行为。 patch 可以替换掉指定的对象,通常用于替换模块中的函数或类。patch 可以作为装饰器、上下文管理器,或直接使用来替换对象. 通过unittest.mock,我们可以方便地控制和断言函数调用和对象的行为,从而使测...
unittest.main(verbosity=2) In this sample test module, you have three test methods. The first one never runs because you use the @skip decorator on it. The second test method only runs if you’re on a Python version equal to or greater than 3.12. Finally, the last test method runs ...

The patch() Function The unittest.mock library provides a powerful mechanism for mocking objects, called patch(), which looks up an object in a given module and replaces that object with a Mock. Usually, you use patch() as a decorator or a context manager to provide a scope in which ...
