Robolectric：如何测试SherlockActivity

Question

我正在尝试在扩展SherlockActivity的Activity上运行测试。 我阅读了所有可以找到的有关使用ActionBarSherlock测试活动的解决方案的信息，还尝试了以下https://github.com/passy/absshadow-sample

这是我目前正在做的：

自定义测试运行器：

public class CustomTestRunner extends RobolectricTestRunner {
    private static final int SDK_INT = Build.VERSION.SDK_INT;

    public CustomTestRunner(Class<?> testClass) throws InitializationError {
        super(testClass);
        addClassOrPackageToInstrument("com.actionbarsherlock.app.SherlockActivity");
    }

    @Override
    protected void bindShadowClasses() {
        super.bindShadowClasses();
        Robolectric.bindShadowClass(ShadowSherlockActivity.class);
    }

    @Override
    public void beforeTest(final Method method) {
        final int targetSdkVersion = robolectricConfig.getSdkVersion();
        setStaticValue(Build.VERSION.class, "SDK_INT", targetSdkVersion);
    }

    @Override
    public void afterTest(final Method method) {
        resetStaticState();
    }

    @Override
    public void resetStaticState() {
        setStaticValue(Build.VERSION.class, "SDK_INT", SDK_INT);
    }
}

影子SherlockActivity：

@Implements(SherlockActivity.class)
public class ShadowSherlockActivity extends ShadowActivity {

    @Implementation
    public void setContentView(int layoutResID) {
        super.setContentView(layoutResID);    // TODO Auto-generated method stub
    }

    @Implementation
    public ActionBar getSupportActionBar() {
        return new ActionBar() {
            // removed for readability
        };
    }
}

由于某种原因，它的失败失败了：

我的活动确实先调用setContentView ，再调用任何findViewById 。

奇怪的是，无论我在setContentView的影子实现中做什么，似乎都没有发生（例如，抛出NullPojnterException ）。 我的影子确实被注册了，好像我尝试覆盖onCreate的实现并将异常抛出在那里，它确实起作用。

我在这里想念什么？

显然，将Intellij项目设置中的Java SDK更改为Oracle而不是OpenJDK可以为我解决此问题。
