Robolectric: how to test a SherlockActivity

Question

I'm trying to run tests on an Activity which extends SherlockActivity. I read everything I could find about the solutions for testing activities with ActionBarSherlock and also tried following https://github.com/passy/absshadow-sample

this is what I'm currently doing:

custom test runner:

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);
    }
}

shadow 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
        };
    }
}

for some reason its aways failing with this:

my activity does call setContentView first, before any findViewById.

the weird part is that no matter what I do in the shadow implementation of setContentView, nothing seems to happen (for example, throwing a NullPojnterException). my shadow does get registered, as if I try to override the implementation of onCreate and throw the exception there, it does work.

what am I missing here ?

Answer 1

apparently changing the Java SDK in Intellij's project settings to Oracle instead of OpenJDK fixed this issue for me.
