我正在使用 Robolectric 2 来测试我的活动。这扩展了 ActionBarActivity：
// This Activity uses one ActionBarCompat theme
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
我的测试是：
@RunWith(RobolectricTestRunner.class)
public class MainActivityTest {
@Test
public void shouldBlaBlaBla() throws Exception {
Robolectric.buildActivity(MainActivity.class).create().get();
assert(...);
}
}
问题是当我告诉 Robolectric 创建 Activity 时，会引发异常。

根据这篇文章，我已将 @Config(reportSdk=10) 添加到我的测试中。结果是我得到的异常不一样了……这一次不是在创建Activity的时候发生的，而是在给Layout充气的时候（Activity使用了扩展@style/Theme.AppCompat的主题）

我错过了什么，还是 Roboelectric2 不应该与 ActionBarCompat 一起工作？
