android – Robolectric与新版Google Play服务的问题

我使用Robolectric进行单元测试,我的项目中有Google Play服务.直到昨天,当Google Play服务更新为新版本时,此工作正常.我收到此错误：

java.lang.NullPointerException
at com.google.android.gms.common.GooglePlayServicesUtil.zzh(UnkNown Source)
at com.google.android.gms.common.GooglePlayServicesUtil.zzd(UnkNown Source)

Process finished with exit code 255

似乎没有调用Shadow类,调用GooglePlayServicesUtil给出NullPointerException.有没有人见过这个？

我甚至不在测试中使用Google Play服务.

解决方法

我添加了下一个解决方法,它工作正常：

>将所有PlayServices的相关代码解压缩到Utility类(在我的例子中,它只是可用性检查)：

public class PlayServicesUtils {

    private static final int PLAY_SERVICES_RESOLUTION_REQUEST = 9000;

    public static final int AVAILABLE = 1;
    public static final int ERROR_RESOLVABLE = 2;
    public static final int ERROR_UNRESOLVABLE = 3;

    @IntDef({AVAILABLE,ERROR_RESOLVABLE,ERROR_UNRESOLVABLE})
    @Retention(RetentionPolicy.soURCE)
    public @interface PlayServicesAvailability {
    }

    @PlayServicesAvailability
    public static int checkPlayServices(@NonNull Activity activity) {
        GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance();
        int resultCode = apiAvailability.isGooglePlayServicesAvailable(activity);
        if (resultCode != ConnectionResult.SUCCESS) {
            if (apiAvailability.isUserResolvableError(resultCode)) {
                apiAvailability.getErrorDialog(activity,resultCode,PLAY_SERVICES_RESOLUTION_REQUEST).show();
                return PlayServicesUtils.ERROR_RESOLVABLE;
            } else {
                CLog.e(Constants.TAG,"This device does not support Google Play services.");
                return PlayServicesUtils.ERROR_UNRESOLVABLE;
            }
        }
        return PlayServicesUtils.AVAILABLE;
    }
}

>为此Utility类实现阴影：

@Implements(PlayServicesUtils.class)
public class ShadowPlayServicesUtils {

    @Implementation
    @PlayServicesUtils.PlayServicesAvailability
    public static int checkPlayServices(@NonNull Activity activity) {
        return PlayServicesUtils.AVAILABLE;
    }
}

>为您的测试类(或基类测试类)添加阴影：

@Ignore
@RunWith(TestRunner.class)
@Config(
        sdk = 18,constants = BuildConfig.class,shadows = {
                ShadowPlayServicesUtils.class
        }
)
public abstract class BaseTest {
    // some code,maybe 
}

>将您的影子添加到TestRunner的InstrumentationConfiguration创建中：

public class TestRunner extends RobolectricGradleTestRunner {
    public TestRunner(Class<?> klass) throws InitializationError {
        super(klass);
    }

    @Override
    public InstrumentationConfiguration createClassLoaderConfig() {
        InstrumentationConfiguration.Builder builder = InstrumentationConfiguration.newBuilder();

        builder.addInstrumentedClass(PlayServicesUtils.class.getName());

        return builder.build();
    }
}

原始答案：

我在Robolectric问题跟踪器上找到了similar issue,并在那里提供了解决方法 – 工作！

只需强制成功初始化Google Play服务：

@Before public void setUp() {
    // force success every time
    ShadowGooglePlayServicesUtil.setIsGooglePlayServicesAvailable(ConnectionResult.SUCCESS);
}

编辑：

但是还有另一个issue Play Services 8.3和8.4.这个问题仍然没有解决.
