有时,仅仅需要mock一个object里的method,而无需mock整个object。 例如,在对当前object的某个method进行测试时。 这时,可以用patch.object。 classForTest: field ='origin'defmethod():passdeftest_for_test(mocker): test = ForTest() mock_method = mocker
def test_function(): mock_object = mocker.Mock() # 执行测试代码 function_under_test(mock_object) # 断言方法被调用一次 assert mock_object.method.call_count == 1 pytest-mock mocker模拟对象构造在以下场景中特别有用: 当需要测试的代码依赖于其他模块或对象时,可以使用模拟对象来模拟这些依赖项,以便能...
Since version1.13, it is also possible to query theside_effectattribute to observe any exception thrown by the spied function/method. Stub 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...

Mock方法是最基础的方法,在使用的使用需要实例化一个对象,设置方法,然后完成模拟。这里有一个问题:没有控制mock范围,控制不精细。完成模拟之后之后,必须把它们复原。如果模拟对象在其它测试中持续存在,那么会导致难以诊断的问题。为此,mock中还提供了 mock.patch和mock.patch.object 等多个对象。mock.patch 是一种...

pytest-mock插件 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。模拟一个object,是最常见的需求。由于function也是一个object,所以以function举例。 代码如下: import os def rm(filename): os.remove(filename) def test_rm(mocke...
mock 有2种场景： 1.直接拦截发出去的请求，还未到达服务端，模拟自定义返回结果 2.发出去的请求，服...
Example: Mock an API call while still tracking its usage. Python import requests class APIClient: def get_data(self, url): return requests.get(url).json() def test_spy_with_patch(mocker): client = APIClient() # Patch the method to return a controlled response mocker.patch.object(client...
