PowerMock + Robolectric + Dagger2

I测试包含定制视图类：PowerMock + Robolectric + Dagger2

机器人UI元素
一些逻辑
静态方法召唤
dagger2依赖性

所以我使用下一个测试工具

Robolectric为嘲笑为逻辑测试
单元测试UI元素
PowerMock静态方法嘲笑

Robolectric + PowerMock集成问题是已知的，溶液是已知的 - https://github.com/robolectric/robolectric/wiki/Using-PowerMock
但是这个解决方案dagger2依赖关系失败。

注意代码。
我的自定义视图：

public class ProgressTextView extends TextView { 

    private String defaultText; 
    private int fileSize; 
    private String fileSizeString; 
    private FileDownloaderI fileDownloader; 

    @Inject 
    FileDownloaderManager fileDownloaderManager; 

    Subscription downloadProgressChannelSubscription; 
    Subscription downloadCancelChannelSubscription; 

    public ProgressTextView(Context context) { 
     super(context); 
     provideDependency(); 
    } 

    public ProgressTextView(Context context, AttributeSet attrs) { 
     super(context, attrs); 
     provideDependency(); 
    } 

    public ProgressTextView(Context context, AttributeSet attrs, int defStyleAttr) { 
     super(context, attrs, defStyleAttr); 
     provideDependency(); 
    } 

    private void provideDependency() { 
     ApplicationSIP.get().applicationComponent().inject(this); 
    } 

}

ProgressTextViewTest：

 
@RunWith(RobolectricUnitTestRunner.class) 
@PowerMockIgnore({ "org.mockito.*", "org.robolectric.*", "android.*" }) 
@PrepareForTest(Formatter.class) 
public class ProgressTextViewTest { 

    Activity activity; 
    @Mock 
    FileDownloaderManager fileDownloaderManager; 

     @Rule 
     public PowerMockRule rule = new PowerMockRule(); 

     @Before 
     public void beforeTest() { 
      // PowerMockito 
      PowerMockito.mockStatic(Formatter.class); 
      when(Formatter.formatFileSize(anyObject(), anyInt())).thenReturn(""); 
      // Mockito 
      MockitoAnnotations.initMocks(this); 
      // Robolectic 
      activity = Robolectric.setupActivity(Activity.class); 
     } 

     @Test 
     public void init_FileDownloaded() { 
      ProgressTextView progressTextView = new ProgressTextView(activity); 
     } 

}

在ProgressTextViewTest错误：

而且有一个麻烦呢。使用Robolectric和dagger2依赖项的其他测试不起作用。

ProgressDownloadViewTest_AudioType：

 
@RunWith(RobolectricUnitTestRunner.class) 
public class ProgressDownloadViewTest_AudioType { 

    Activity activity; 
    @Mock 
    FileDownloaderManager fileDownloaderManager; 
    @Mock 
    MediaManager mediaManager; 

     @Before 
     public void setup() { 
      // Mockito 
      MockitoAnnotations.initMocks(this); 
      // Robolectic 
      activity = Robolectric.setupActivity(Activity.class); 
     } 

     @Test 
     public void setDownloadingState_emptyFileDownloaderI() { 
      ProgressDownloadView progressDownloadView = new ProgressDownloadView(activity, ProgressDownloadView.Type.AUDIO); 
      ... 
     } 

}

例外：

You might experience classloading issues, disabling the Objenesis cache *might* help (see MockitoConfiguration)

我不打算试图通过所有这些代码，有太多。只输入相关的代码。 –

@MsYvette，以便您可以观看ProgressTextView，ProgressTextViewText和ProgressTextViewTest错误。我离开其他班以防万一 –

我不确定没有经历它，抱歉我也在工作，所以不能给它足够的时间。想想，这是另一个人了解我的问题的必要吗？太多的代码会让人们忽略它，这就是我的观点。 –

Activity activity; 
@Mock 
FileDownloaderManager fileDownloaderManager; 

    @Rule 
    public PowerMockRule rule = new PowerMockRule(); 

    @Before 
    public void beforeTest() { 

     // You intialise activity here 
     activity = Robolectric.setupActivity(Activity.class); 
    } 

    @Test 
    public void init_FileDownloaded() { 

     // and use it here, the initialisation is out of scope for this 
     ProgressTextView progressTextView = new ProgressTextView(activity); 
    }

您需要更改程序逻辑允许这样的事情：

Activity activity; 
@Mock 
FileDownloaderManager fileDownloaderManager; 

    activity = Robolectric.setupActivity(Activity.class); 

    @Rule 
    public PowerMockRule rule = new PowerMockRule(); 

    @Before 
    public void beforeTest() { 

    } 

    @Test 
    public void init_FileDownloaded() { 

     ProgressTextView progressTextView = new ProgressTextView(activity); 
    }

而且

ApplicationSIP.get().applicationComponent().inject(this);

我不知道你指的是作为this

我看不到你身在何处，你initialsing FileDownloaderManager什么类，但似乎你正在尝试使用自定义管理器作为内置的Android管理器。

Caused by: java.lang.ClassCastException: Cannot cast com.tg.osip.tdclient.update_managers.FileDownloaderManager$$EnhancerByMockitoWithCGLIB$$a751cd05 to com.tg.osip.tdclient.update_managers.FileDownloaderManager 
at java.lang.Class.cast(Class.java:3369)

我希望这有助于让你更清楚一点。

我需要寻找类铸造异常挂在 –

谢谢，我会尝试 –

@ xoxol_89我编辑过。那里有很多。我建议你可以在这里拿出你能发现的更清晰的问题。 –
