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?
