PowerMock + Robolectric +匕首2 [英] PowerMock + Robolectric + Dagger2
本文介绍了PowerMock + Robolectric +匕首2的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我测试包含以下内容的自定义视图类：
I test custom view class which contain:
- android ui元素
- 一些逻辑
- 静态方法调用
- dagger2依赖项
- android ui elements
- some logic
- static methods callings
- dagger2 dependencies
所以我使用下一个工具进行测试
So i use next tools for testing
- Robolectric用于模拟UI元素
- 用于逻辑测试的单元测试
- 用于静态方法模拟的PowerMock
Robolectric + PowerMock集成问题已知，解决方案已知- https://github.com/robolectric/robolectric/ wiki / Using-PowerMock
但是使用此解决方案，dagger2依赖项失败。
注意编码。
我的自定义视图：
Robolectric + PowerMock integration problem is known and solution is known - https://github.com/robolectric/robolectric/wiki/Using-PowerMock
But with this solution dagger2 dependencies fail.
Attention to code.
My custom view:
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：
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);
}
}
In ProgressTextViewTest错误：
In ProgressTextViewTest error:
java.lang.NullPointerException

有一个麻烦了。其他具有Robolectric和dagger2依赖项的测试无法正常工作。
ProgressDownloadViewTest_AudioType：
And there is one trouble yet. Other tests with Robolectric and dagger2 dependencies are not working.
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：
ClassCastException occurred while creating the mockito proxy :

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

解决 PowerMock + Robolectric + Dagger2。第一部分
推荐答案
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以允许如下所示：
You need to change your program logic to allow for something like this:
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);
}
也
ApplicationSIP.get().applicationComponent().inject(this);
我不确定您指的是 this
我看不到您在类中初始化 FileDownloaderManager 的位置，但看来您正在尝试将自定义管理器用作内置的android管理器。
I cannot see where you are initialsing FileDownloaderManager in you classes, but it seems you are attempting to use the custom manager as the inbuilt android manager.
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)
我希望这有助于使您更加清晰。
I hope this helps to get you a little clearer.
