Thanks for letting me know about the broken links. It looks like those links are no longer allowed so I'm trying to find out an alternative.
Also, Beta2 should be out in the next couple of days so I'll be editing that download page anyway.
MyFaces 1.1 is still supported in JSFUnit 2. I think the Spring issue you are referring to is one with special scopes. JSFUnit can handle the custom scopes used in JSF2, but (except for Seam) it does not recognize scopes created outside of JSF. I don't personally use Spring but some others on this forum might be able to give you some tips. I'd suggest starting a new thread for your specific problem.
The downloads page is now fixed. You can download Beta 2 from there.
