莫基托.验证方法参数

2022-01-14 00:00:00 unit-testing mockito java junit

我用谷歌搜索过这个，但没有找到任何相关的东西.我有这样的东西:

I've googled about this, but didn't find anything relevant. I've got something like this:

Object obj = getObject();
Mockeable mock= Mockito.mock(Mockeable.class);
Mockito.when(mock.mymethod(obj )).thenReturn(null);

Testeable testableObj = new Testeable();
testableObj.setMockeable(mock);
command.runtestmethod();

现在，我想验证在 runtestmethod() 内部调用的 mymethod(Object o) 是否被 Object o，没有其他.但我总是通过测试，无论我在验证中添加什么，例如:

Now, I want to verify that mymethod(Object o), which is called inside runtestmethod(), was called with the Object o, not any other. But I always pass the test, whatever I put on the verification, for example, with:

Mockito.verify(mock.mymethod(Mockito.eq(obj)));

或

Mockito.verify(mock.mymethod(Mockito.eq(null)));

或

Mockito.verify(mock.mymethod(Mockito.eq("something_else")));

我总是通过考试.我怎样才能完成该验证(如果可能)?

I always pass the test. How can I accomplish that verification (if possible)?

谢谢.

推荐答案

ArgumentMatcher 的替代方案是 ArgumentCaptor.

An alternative to ArgumentMatcher is ArgumentCaptor.

官方示例:

ArgumentCaptor<Person> argument = ArgumentCaptor.forClass(Person.class);
verify(mock).doSomething(argument.capture());
assertEquals("John", argument.getValue().getName());

还可以使用 @Captor 注释:

@Captor ArgumentCaptor<Person> captor;
//... MockitoAnnotations.initMocks(this);
@Test public void test() {
    //...
    verify(mock).doSomething(captor.capture());
    assertEquals("John", captor.getValue().getName());
}
