"By the way I indeed have couple ideas how to make testing process more
effortless", great, love to hear them !

Hi Vladimir,

I like your effortless's ideas. One important thing we plan to do is to
have a good FishCAT test framework,
so FishCATs can contribute the test cases in the common test framework.
There is no hurry on this. Let's
first ship v3, then we come to work on this. But meanwhile, would like
every one continue thinking what would be good
choice.

Thanks,
Judy
