我正在使用 Robolectric 2 来测试我的 Activity 。 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，抛出了一个异常。

基于 this帖子，我已经将 @Config(reportSdk=10) 添加到我的测试中。结果是我得到的异常是不同的...这次不会发生在创建 Activity 时，而是在扩充 Layout 时(Activity 使用扩展 @style/Theme.AppCompat 的主题)

我是不是遗漏了什么，或者 Roboelectric2 不应该与 ActionBarCompat 一起工作？
最佳答案
我也遇到了这个问题。
看起来 版本 2.3-SNAPSHOT(在 sonatype 上可用)修复了它
