guice java.lang.ClassCastException:无法将对象_代理强制转换为android.net.ConnectionManager

您好，我在我的项目中使用RoboGuice和Mockito，我在测试中遇到了解决

SystemServices

的问题

我上了一节课

public class RoboInstrumentationTestCase extends InstrumentationTestCase {

protected Application application;
protected Context context;
protected Injector injector;

@Override
protected void setUp() throws Exception {
    application = mock(Application.class, RETURNS_DEEP_STUBS);
    context = mock(RoboActivity.class, RETURNS_DEEP_STUBS);
    injector = RoboGuice.setBaseApplicationInjector(application, RoboGuice.DEFAULT_STAGE, 
            Modules.override(RoboGuice.newDefaultRoboModule(application)).
            with(   new UtilModule(),
                    new DatabaseModule(), 
                    new FixtureModule(),
                    new RepositoryModule(),
                    new ServiceCoreModule(),
                    new ServiceModule()
                    ));
    when(context.getApplicationContext()).thenReturn(application);
    when(application.getApplicationContext()).thenReturn(application);

    super.setUp();
}

@Override
protected void tearDown() throws Exception {
    super.tearDown();
    RoboGuice.util.reset();
}

protected Injector getInjector() {
    return injector;
}
}

在另一个类中，我需要检索

ConnectivityManager

public class ConnectivityUtilImpl implements ConnectivityUtil {

private ConnectivityManager connectivityManager;

@Inject
public void setConnectivityManager(ConnectivityManager connectivityManager) {
    this.connectivityManager = connectivityManager;
}

/* (non-Javadoc)
 * @see com.devsu.supermaxi.util.impl.ConnectivityUtil#getNetworkInfo(android.content.Context)
 */
@Override
public NetworkInfo getNetworkInfo(){
    return connectivityManager.getActiveNetworkInfo();
}

但我得到了以下错误：

请允许我建议一种“保持简单”的方法，只需模拟一下

ConnectivityManager

和

NetworkInfo

，这就是您测试这个类所需的全部内容非常感谢，您是对的。。我不考虑你的建议
