二.Android单元测试 Mockito的更多用法

一.Android单元测试 Mockito的简单用法
三.Android单元测试 PowerMock给私有变量赋值
四.Android单元测试 PowerMock mock静态方法

 相对于上篇文章,这篇介绍了更多mockito的用法,对照着MeetingPresenterImp.java和MeetingPresenterImpTest.java大家可以看看Android单元测试用例怎么写.

public class MeetingPresenterImp implements MeetingContract.MeetingPresenter {    private MeetingController meetingController;    private MeetingAudioManager audioManager;    private MeetingContract.MeetingView meetingView;    private MeetingParticipant localParticipant;    public MeetingPresenterImp(MeetingContract.MeetingView meetingView, MeetingController meetingController, MeetingAudioManager audioManager) {        this.meetingController = meetingController;        this.audioManager = audioManager;        this.meetingView = meetingView;    }    //开关摄像头    @Override    public void toggleCamera() {        meetingController.toggleCamera();    }    //开关扬声器    @Override    public void toggleSpeaker() {        if (audioManager.isSpeakerOn()) {            audioManager.turnOffSpeaker();        } else {            audioManager.turnOnSpeaker();        }    }    //设置Orientation    public void setOrientation(int orientation) {        meetingController.setOrientation(orientation);    }    //更新MainView的可见度    public void updateMainViewVisibility(boolean isShowAllButtons) {        meetingView.updateButtonsVisibility(isShowAllButtons);        meetingView.updateSelfSurfaceVisibility(isShowAllButtons);        meetingView.updateSelfIconVisibility(isShowAllButtons);    }    //更新会议时间    public void updateMeetingTime(long time) {        Date d = new Date(time);        SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss", Locale.US);        sdf.setTimeZone(TimeZone.getTimeZone("UTC"));        meetingView.updateTime(sdf.format(d));    }    //观看某位与会人的视频源    synchronized void startWatchVideoSource(MeetingParticipant participant, long mainSourcePtr, long minSourcePtr) {        if (participant == null || participant.isBeingWatched()) {            return;        }        if (participant.equals(localParticipant)) {            meetingController.setSelfPreviewView(mainSourcePtr, minSourcePtr);        } else {            meetingController.startWatchVideoSource(participant.getUri(), mainSourcePtr, 0, 960, 720, 20, 0);        }        participant.setBeingWatched(true);    }}

@RunWith(MockitoJUnitRunner.class)public class MeetingPresenterImpTest {    @Mock    MeetingContract.MeetingView meetingView;    @Mock    MeetingController meetingController;    @Mock    MeetingAudioManager meetingAudioManager;    MeetingPresenterImp meetingPresenterImp;    private Random random = new Random();    @Before    public void setUp() throws Exception {        meetingPresenterImp = new MeetingPresenterImp(meetingView, meetingController, meetingAudioManager);    }    //简单的验证方法是否执行    @Test    public void toggleCamera() throws Exception {        meetingPresenterImp.toggleCamera();        Mockito.verify(meetingController).toggleCamera();    }    //使用when().thenReturn控制mock对象的方法的返回值    @Test    public void should_turn_off_speaker() throws Exception {        Mockito.when(meetingAudioManager.isSpeakerOn()).thenReturn(true);        meetingPresenterImp.toggleSpeaker();        Mockito.verify(meetingAudioManager).turnOffSpeaker();    }    //同上,但是测试的是另外一个分支,这里isSpeakerOn()返回false    @Test    public void should_turn_on_speaker() throws Exception {        Mockito.when(meetingAudioManager.isSpeakerOn()).thenReturn(false);        meetingPresenterImp.toggleSpeaker();        Mockito.verify(meetingAudioManager).turnOnSpeaker();    }    //测试方法执行还不够,测试传入的参数是否一致    @Test    public void should_set_orientation() throws Exception {        meetingPresenterImp.setOrientation(0);        verify(meetingController).setOrientation(0);    }    //使用inOrder()测试方法是否按特定顺序执行    @Test    public void should_update_main_view_visibility() throws Exception {        boolean isShowAllButtons = random.nextBoolean();        meetingPresenterImp.updateMainViewVisibility(isShowAllButtons);        InOrder inOrder = inOrder(meetingView);        inOrder.verify(meetingView).updateButtonsVisibility(isShowAllButtons);        inOrder.verify(meetingView).updateSelfSurfaceVisibility(isShowAllButtons);        inOrder.verify(meetingView).updateSelfIconVisibility(isShowAllButtons);    }    //测试一个String被format后的值是否和想要的一致,情况一    @Test    public void should_update_meeting_time_30_seconds() throws Exception {        meetingPresenterImp.updateMeetingTime(30 * 1000);        verify(meetingView).updateTime("00:00:30");    }    //测试一个String被format后的值是否和想要的一致,情况二    @Test    public void should_update_meeting_time_61_seconds() throws Exception {        meetingPresenterImp.updateMeetingTime(61 * 1000);        verify(meetingView).updateTime("00:01:01");    }    //使用never测试一个方法一次都没有被执行    @Test    public void should_start_watch_video_source_when_participant_is_null() throws Exception {        meetingPresenterImp.startWatchVideoSource(null, 0, 0);        verify(meetingController, never()).setSelfPreviewView(anyLong(), anyLong());        verify(meetingController, never()).startWatchVideoSource(anyString(), anyLong(), anyInt(), anyInt(), anyInt(), anyInt(), anyInt());    }}
