The stub is a mock object that accepts any arguments and is useful to test callbacks, for instance. May be passed a name to be used by the constructed stub object in its repr (useful for debugging). deftest_stub(mocker):deffoo(on_something): on_something('foo','bar') stub= mocker....
pytest-mock是一个pytest的插件,安装即可使用。 它提供了一个名为mocker的fixture,仅在当前测试function或method生效,而不用自行包装。 object mock一个object,是最常见的需求。 由于function也是一个object,以下以function举例。 import os def rm(filename): os.remove(filename) def test_rm(mocker): filename ...

mocker Fixture是MockFixture类的一个实例,该类是unittest.mock模块的一个子类。 它提供了以下方法: mocker.patch - 补丁一个函数或方法 mocker.patch.object - 补丁一个对象的方法 mocker.patch.multiple - 补丁多个函数或方法 mocker.patch.dict - 补丁一个字典 ...

Pytest提供了unittest.mock模块,便于创建和管理模拟对象(mock objects)。 例如,假设我们的代码需要调用一个HTTP API获取天气预报,但在此测试中我们并不想真正发起网络请求,而是使用模拟响应。这时可以使用unittest.mock.patch.object或unittest.mock.MagicMock: from unittest.mock import MagicMock, patch from my_weather...
In these cases, a mock object can be created to simulate the hardware. The mock object can return the command that was sent and returns pre-programmed responses in a short amount of time. This is an important benefit as in many cases, hardware responses can be slow. ...
or mock a function, because a function is an object in Python and the attribute in this case is its return value. Let’s go through each one of them. Recipes for using mocks in pytest We will usepytest-mockto create the mock objects. ...
