如何对异步交互器进行单元测试？

Question

我在junit测试中是全新的，我需要测试一些带有异步调用的交互器。我的问题是我不明白在不破坏测试统一性的情况下我需要测试什么。

如果我测试对interactor.execute（）的纯调用，我也会测试其他的interactors功能。我可以模拟交互器依赖项，但它们被引入。我知道这是一个概念上的误解，它必须比我想象的容易得多。

public class NewLoginInteractorImpl implements NewLoginInteractor {

    private final GetRegistrationIdInteractor getRegistrationIdInteractor;
    private final GetDeviceIdInteractor getDeviceIdInteractor;
    private final GetAndroidOSVersionInteractor getAndroidOSVersionInteractor;
    private final NewLoginWebService newLoginWebService;
    private static final String TAG = "NewLoginInteractorImpl";


    @Inject
    public NewLoginInteractorImpl(GetRegistrationIdInteractor getRegistrationIdInteractor, GetDeviceIdInteractor getDeviceIdInteractor, GetAndroidOSVersionInteractor getAndroidOSVersionInteractor, NewLoginWebService newLoginWebService) {
        this.getRegistrationIdInteractor = getRegistrationIdInteractor;
        this.getDeviceIdInteractor = getDeviceIdInteractor;
        this.getAndroidOSVersionInteractor = getAndroidOSVersionInteractor;
        this.newLoginWebService = newLoginWebService;
    }

    @Override
    public void execute(final Callback callback) {
        final String deviceId = getDeviceIdInteractor.execute();
        final String os_version = getAndroidOSVersionInteractor.execute();
        getRegistrationIdInteractor.execute(new GetRegistrationIdInteractor.Callback() {
            @Override
            public void onSuccess(String regid) {
                NoLoginUser noLoginUser = new NoLoginUser(deviceId, regid, os_version);
                callNoLoginWebService(noLoginUser, callback);
            }

            @Override
            public void onFailure(String error) {
                callback.onFailureGettingRegistrationId(error);
            }

            @Override
            public void onRecoverableError(int resultCode, int playServicesResolutionRequest) {
                callback.onRecoverableError(resultCode, playServicesResolutionRequest);
            }
        });
    }

    private void callNoLoginWebService(NoLoginUser noLoginUser, final Callback callback) {

        newLoginWebService.noLogin(noLoginUser, new NewLoginWebService.Callback() {

            @Override
            public void onNoLoginFailure(String errorText) {
                callback.onNoLoginFailure(errorText);
            }

            @Override
            public void onNoLoginInvalidValues(JSONObject error) {
                callback.onFailureGettingRegistrationId("ERROR");
            }

            @Override
            public void onNoLoginSuccess(JSONObject response) {
                callback.onSuccess(response);
            }

            @Override
            public void onNullResponse() {
                callback.onNullResponse();
            }
        });
    }
}
