的Mockito：java.lang.ClassCastException：java.lang.Boolean中不能转换到DataListListener

Question

我试图使用到的Mockito执行单元测试，但测试失败我正在此：

的java .lang.ClassCastException：java.lang.Boolean的不能转换到 OnDataListListener

在这里这条线：mPresenter.getUsers(isLoad, forceUpdate);

测试：

doAnswer(answerVoid(
     (OnDataListListener<List<User>> myCallback) -> myCallback.onSuccess(mList))).when(
     dataInteractor).getUsers(anyBoolean(), any(DataListener.class)); 

    mPresenter.getUsers(isLoad, forceUpdate); 

演示

@Override public void getUsers(boolean isLoad, boolean update) { 
    this.isLoad = isLoad; 
    this.forceUpdate = update; 
    dataInteractor.performgetUsers(update, this);//this refer to the listener 
    } 

DataInteractor：

public void performGetGetUsers(boolean update, OnDataListListener callback) { 
    mDataHandler.getUsers(update, new Observer<List<User>>() { 
.... 

的侦听器接口：

public interface DataListener<T> { 
    void onSuccess(T data); 

    void onFailure(Throwable e); 
} 

Answer 1

这是如此怪异，但切换PARAMS解决的问题！

dataInteractor.performgetUsers(update, this);//this refer to the listener 

到

dataInteractor.performgetUsers(this, update);//this refer to the listener
