Adam, Darin, thank you for your feedback! - and sorry for slow reply.

The last patch split test-specific code out from WebCore.framework into WebCoreTesting.framework.
An idea is:
- WebCore providing hook interface and JS stub for that.
- WebCoreTesting use that interface to inject a test-specific code
- WebKit provide a API for WebCoreTesting, while linking WebCoreTesting.framework with "weak" linkage,
   that allow us to ship WebKit.framework without WebCoreTesting.framework.

The source code for WebKitTesting still stays WebCore/testing/ and built inside WebCore.xcodeproj
So it can access WebCore APIs.
A tradeoff is that we need to expose WebCore APIs that are required by WebCoreTesting.
But I think it need less hassle than wrapping and exposing it via WebKit.

I'm not sure if weak linkage is available for other port 
but I believe there are some workaround for that. 
(i.e. just built WebCore/testing/* into DRT.)

Any ideas and feedbacks are welcome!
