Answer 1

是的，当风味具有不同的应用程序ID时，这是一个已知问题。您可以使用packageName属性来解决此问题。 https://github.com/robolectric/robolectric/issues/2110

@Config(packageName = "app.base.package.name")

Answer 2

尝试使用自定义的roboletric测试运行器类来告诉roboletric资源类的位置：

public class CustomRobolectricGradleTestRunner extends RobolectricGradleTestRunner {

    public CustomRobolectricGradleTestRunner(Class<?> klass) throws InitializationError {
        super(klass);
    }

    // Fix for the NotFound error with openRawResource()
    @Override
    protected AndroidManifest getAppManifest(Config config) {
        String manifest = "src/main/AndroidManifest.xml";
        String res = String.format("../app/build/intermediates/res/merged/%1$s/%2$s", BuildConfig.FLAVOR, BuildConfig.BUILD_TYPE);
        String asset = "src/test/assets";
        return new AndroidManifest(Fs.fileFromPath(manifest), Fs.fileFromPath(res), Fs.fileFromPath(asset));
    }
}

在测试类中，指定自定义测试运行器类，如：

@Config(constants = BuildConfig.class)
@RunWith(CustomRobolectricGradleTestRunner.class)
public class DataServiceTest {
}

Robolectric抛出ResourceNotFound异常
