Question

我正在尝试使用mockito进行单元测试，但是测试失败我得到了这个：

java.lang.ClassCastException：java.lang.Boolean无法强制转换为 OnDataListListener

此行：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>>() {
....

侦听器界面：

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

  void onFailure(Throwable e);
}

Answer 1

这太奇怪了，但转换参数解决了这个问题！

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

到

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

Mockito：java.lang.ClassCastException：java.lang.Boolean不能强制转换为DataListListener
