How to add shadow class when using Robolectric 2.2?

Question

I am using Robolectric for my Unit testing and updated my Robolectric jar from 1.2 to 2.2 and trying to figure out how to bind shadow classes in this new version. This is what I was doing before:

Robolectric.bindShadowClass(ShadowLog.class);

@Implements(Log.class)
public static class ShadowLog {
    public static int i(java.lang.String tag, java.lang.String msg) {
        System.out.println("[" + tag + "] " + msg);
        return 0;
    }
}

But I think now there is no bindShadowClass API available. I tried using addShadowClass but I am not sure if this is the right way to add a shadow class. Can I just use

ShadowMap a = new ShadowMap.Builder().addShadowClass(ShadowLog.class).build();

Do I need to create a classHandler or something using this shadowMap and if yes, how do I create and use that classHandler to get access to my Log class methods?

@Implements(Log.class)
public static class ShadowLog {
    public static int i(java.lang.String tag, java.lang.String msg) {
        System.out.println("[" + tag + "] " + msg);
        return 0;
    }
}

And then Log.i("LogTest", "log message ");

Thanks Abhi

The binding of shadow classes is now replaced with @Config annotations.

Example:

@Config(shadows = {ShadowLog.class})
