Hey, this is great, thanks for creating this!

I'm looking forward to moving as many of my current set of tests to your
framework as I can:

http://git.yoctoproject.org/cgit/cgit.cgi/linux-yocto-contrib/commit/?h=tzanussi/hist-triggers-test&id=53d7d47bac3340b2160bf2a5b48268d6c7516734

I run all of the above tests manually every time I make a significant
change, which is about 2 hours of solid tedious work each time through.
Obviously it's about time to automate - thanks for providing the
framework to finally help do that.

Sure, I'll do that, new series coming up shortly..

Thanks,
