Ich habe angefangen, eine seltsame ClassCastException in Mockito zu treffen, wenn ich es mit Robolectric verwende. Wenn ich dieselben Tests ohne Robolectric Runner durchführe, läuft alles gut, es wird keine Ausnahme geworfen. HierMockito mit Robolectric: "ClassCastException trat beim Erstellen des Proxys auf"
ist Stack-Trace:
org.mockito.exceptions.base.MockitoException:
ClassCastException occurred when creating the proxy.
You might experience classloading issues, disabling the Objenesis cache *might* help (see MockitoConfiguration)

Der Code, den ich verwende, ist wie folgt:
@RunWith(ApplicationTestRunner.class)
public class ObservableCacheDispatcherTest {
@Mock
private IDataMapper mockDataMapper;
@Mock
private ICache mockCache;
@Mock
private Function0<Object> mockLoader;
private ObservableCacheDispatcher cacheDispatcher;
@Before
public void setUp() {
MockitoAnnotations.initMocks(this); // <-- exception happens when executing this statement
cacheDispatcher = new ObservableCacheDispatcher(mockCache, mockDataMapper);
}
...
}
Dies ist, wie Robolectric Läufer wie folgt aussehen:
public class ApplicationTestRunner extends RobolectricTestRunner {
//Maximun SDK Robolectric will compile (issues with SDK > 18)
private static final int MAX_SDK_SUPPORTED_BY_ROBOLECTRIC = 18;
private static final String ANDROID_MANIFEST_PATH = "../app/src/main/AndroidManifest.xml";
private static final String ANDROID_MANIFEST_RES_PATH = "../app/src/main/res";
/**
* Call this constructor to specify the location of resources and AndroidManifest.xml.
*
* @throws org.junit.runners.model.InitializationError
*/
public ApplicationTestRunner(Class<?> testClass) throws InitializationError {
super(testClass);
}
@Override protected AndroidManifest getAppManifest(Config config) {
return new AndroidManifest(Fs.fileFromPath(ANDROID_MANIFEST_PATH),
Fs.fileFromPath(ANDROID_MANIFEST_RES_PATH)) {
@Override
public int getTargetSdkVersion() {
return MAX_SDK_SUPPORTED_BY_ROBOLECTRIC;
}
};
}
}
Was sollte Ich repariere, um diese Ausnahme loszuwerden?
Interessant! Ich vermute nur, dass etwas mit Kotlin/Robolectric kollidiert. Ersetzt Kotlin ClassLoader? Ich hoffe, Kotlin Experten werden beitreten Konversation –
Können Sie die Lösung von hier https://github.com/robolectric/robolectric-gradel-plugin/issues/75 –
@EugenMartynov guter Punkt, habe ich "Kotlin" -Tag, vielleicht Kotlin hinzugefügt Jungs würden helfen. –
