PowerMockito如何捕获传递给模拟对象的参数？

Question

我正在尝试使用PowerMockito捕获输入传递给模拟对象的参数，这是代码：

//I create a mock object
ClassMocked mock = PowerMockito.mock(ClassMocked.class);

//Create the captor that will capture the String passed in input to the mock object
ArgumentCaptor<String> argumentCaptor = ArgumentCaptor.forClass(String.class);

//When the method put is executed on my mock I want the second parameter (that is a String) to be captured
Mockito.verify(mock).put(anyString(), inputDataMapCaptor.capture());

//Creates the instance of the class that I want to test passing the mock as parameter
ClassToTest instance = new ClassToTest(mock);

//Executes the method that I want to test
instance.methodToTest();

/* I know that during the execution of "methodToTest()" mock.put(String,String) will be executed and I want to get the second string parameter. */

当我执行测试时，我有一个异常执行行Mockito.verify（mock）.put（...）;

“通缉但未调用mock.put（任何，捕获参数）;”

有什么问题？

Answer 1

您应该在instance.methodToTest();

之前致电Mockito.verify(mock).put(anyString(), inputDataMapCaptor.capture());

Answer 2

verify() 验证指定的方法调用是否。

您无法提前验证＆＃34;应该发生方法调用。

因此：verify()需要在事实之后发生，而不是之前！
