Android mockito mocking callback












1















I am testing an interactor that returns a callback to a class.
here is the code -



Presenter



public MyPresenter() implements MyInteractorCallback {
MyInteractorImpl interactorImpl = new MyInteractorImpl(this);

interactorImpl.doSomething(obj);

@Override
public void statusChange(String status) {
//.....
}
}


InteractorImpl



public MyInteractorImpl() {

MyInteractorCallback callback;

public MyInteractorImpl(final MyInteractorCallback callback) {
this.callback = callback;
}

public void doSomething(MyObj obj) {
callback.statusChange("OK");
//....
callback.statusChange("NO");
}
}


InteractorCallback



Interface MyInteractorCallback {
void statusChange(String status);
}


MyTest



@Test
public void testMyObj() {
obj = new MyObj();
callback = mock(MyInteractorCallback.class);
MyInteractorImpl impl = new MyInteractorImpl(callback);
impl.doSomething(obj);
verify(callback).statusChange("NO");
}


This throws me an error -



Wanted but not invoked:
callback.statusChange(
OK
);

However, there was exactly 2 interaction with this mock:


What exactly is this error? How can i get rid of this?

          That error should mean that you have somewhere in your testcode you run verify(callback).statuschange("OK"). Maybe you have mixed up OK and NO somewhere?
