我通过ArgumentCaptor捕获Class参数时遇到问题.我的测试类看起来像这样:

@RunWith(RobolectricGradleTestRunner::class)
@Config(sdk = intArrayOf(21), constants = BuildConfig::class)
class MyViewModelTest {
    @Mock
    lateinit var activityHandlerMock: IActivityHandler;

    @Captor
    lateinit var classCaptor: ArgumentCaptor<Class<BaseActivity>>

    @Captor
    lateinit var booleanCaptor: ArgumentCaptor<Boolean>

    private var objectUnderTest: MyViewModel? = null

    @Before
    fun setUp() {
        initMocks(this)
        ...
        objectUnderTest = MyViewModel(...)
    }

    @Test
    fun thatNavigatesToAddListScreenOnAddClicked(){
        //given

        //when
        objectUnderTest?.addNewList()

        //then
        verify(activityHandlerMock).navigateTo(classCaptor.capture(), booleanCaptor.capture())
        var clazz = classCaptor.value
        assertNotNull(clazz);
        assertFalse(booleanCaptor.value);
    }
}

当我运行测试,下面抛出异常:
java.lang.IllegalStateException:classCaptor.capture()不能为null
是否可以使用参数的俘虏在科特林？

=========更新1:
Kotlin:1.0.0-beta-4584
Mockito:1.10.19
Robolectric:3.0

=========更新2:

我正在使用此处提供的示例应用程序测试Nearby connection API:https://github.com/googlesamples/android-nearby 似乎这对某些设备不起作用.我成功地将三星Galaxy S3与Nexus 7连接在一起(S3作为主机,N7作为从机,反之亦然).但是,当我尝试将Samusung Galaxy S3连接到Nexus 5时,连接总是失败,状态代码为8005.

您可以在下面看到slave(发现设备)调用的方法,以便连接到主机(广告设备).

private void connectTo(String endpointId, final String endpointName) {
    debugLog("connectTo:" + endpointId + ":" + endpointName);

    // Send a connection request to a remote endpoint. By passing 'null' for the name,
    // the Nearby Connections API will construct a default name based on device model
    // such as 'LGE Nexus 5'.
    String myName = null;
    byte[] myPayload = null;
    Nearby.Connections.sendConnectionRequest(mGoogleApiClient, myName, endpointId, myPayload,
            new Connections.ConnectionResponseCallback() {
                @Override
                public …

我正在尝试测试,如果新创建的Activity(在方向更改后)正确地重新初始化.下面的代码显示从getActivity()返回的活动是在setUp()中构造的活动,而不是新创建的活动.

测试:

public class MyActivityTest extends ActivityInstrumentationTestCase2<MyActivity>{
 private static final String TAG = "RAMPS";
 private MyActivity mActivity;

 public MyActivityTest() {
    super("com.ramps", MyActivity.class);       
 }

 protected void setUp() throws Exception {
     super.setUp();
     mActivity = getActivity();
     Log.v(TAG, "setUp; activity=" + mActivity);
 }

public void testOrienationChange(){
     mActivity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
     getInstrumentation().waitForIdleSync();
     MyActivity newActivity = getActivity(); //should be new, but it's not
     Log.v(TAG, "testOrienationChange; activity=" + newActivity);       
 }
}

Activiy:

public class MyActivity extends Activity {
    private static final String TAG = "RAMPS";  

 public void onCreate(Bundle savedInstanceState) { …

登录失败时，我想将用户重定向到错误页面并显示有意义的错误消息。是否可以添加将传递给后续请求的 Flash 属性？

下面显示的代码不起作用。RequestContextUtils.getOutputFlashMap()返回null。

public class CustomAuthenticationFailureHandler implements AuthenticationFailureHandler
{
    @Override
    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException
    {
        FlashMap outputFlashMap = RequestContextUtils.getOutputFlashMap(request);
        if (outputFlashMap != null)
        {
            outputFlashMap.put("error", "Error message");
        }
        response.sendRedirect(request.getContextPath() + "/error");
    }
}
