android - 使用 Robolectric 2 测试可序列化的包裹

Question

我想测试我的类是否在 Parcel 中写入了正确的数据，所以我写了以下测试:

@Test
public void parcelOutAndIn() {
    Trip trip = new Trip("id123", new Date());

    Parcel parcel = Parcel.obtain();
    trip.writeToParcel(parcel, 0);
    Trip tripResult = new Trip(parcel);

    Assert.assertThat(tripResult.getId(), equalTo(trip.getId()));
    Assert.assertThat(tripResult.getStartTime(), equalTo(trip.getStartTime()));
}

我的 writeToParcel 看起来像这样:

@Override
public void writeToParcel(Parcel parcel, int i) {
    parcel.writeString(id);
    parcel.writeSerializable(startTime);
}

我有以下错误:

java.lang.NoSuchMethodError: java.util.Arrays.checkOffsetAndCount

我能做什么？这是 Robolectric 中的错误吗？我使用 Robolectric 2.1.1。

遗憾的是，Roboelectric 的 ShadowParcel 不包含 writeByteArray() 方法的实现。
