Mockito 可以捕获多次调用的方法的参数吗?-Java问题

Can Mockito capture arguments of a method called multiple times?(Mockito 可以捕获多次调用的方法的参数吗?)

问题描述

我有一个被调用两次的方法，我想捕获第二个方法调用的参数.

I have a method that gets called twice, and I want to capture the argument of the second method call.

这是我尝试过的:

ArgumentCaptor<Foo> firstFooCaptor = ArgumentCaptor.forClass(Foo.class);
ArgumentCaptor<Foo> secondFooCaptor = ArgumentCaptor.forClass(Foo.class);
verify(mockBar).doSomething(firstFooCaptor.capture());
verify(mockBar).doSomething(secondFooCaptor.capture());
// then do some assertions on secondFooCaptor.getValue()

但是我得到一个 TooManyActualInvocations 异常，因为 Mockito 认为 doSomething 应该只被调用一次.

But I get a TooManyActualInvocations Exception, as Mockito thinks that doSomething should only be called once.

如何验证 doSomething 的第二次调用的参数?

How can I verify the argument of the second call of doSomething?

推荐答案

我觉得应该是

verify(mockBar, times(2)).doSomething(...)

来自 mockito javadoc 的示例:

ArgumentCaptor<Person> peopleCaptor = ArgumentCaptor.forClass(Person.class);
verify(mock, times(2)).doSomething(peopleCaptor.capture());

List<Person> capturedPeople = peopleCaptor.getAllValues();
assertEquals("John", capturedPeople.get(0).getName());
assertEquals("Jane", capturedPeople.get(1).getName());
