Capture body of failed tests

[giorgiosironi]

It would be interesting to store this body along with the counters, for debugging purposes like a smoke_debug function that would print what happened. Would be interested in a pull request for that?

I like the idea, but I'm not sure what it would look like yet. At the end of the run the cleanup function will remove all debug data. Perhaps the thing we could do in debug mode is:

• exit on the first failure
• echo the location of the intermediate (debug) data and not clean it up

Activating the feature could be based on an env var?

More than a debug mode, I thought about a debug function because typically smoke tests results may be not reproducible. So it's important to store a bad result when it's encountered, and the user can decide to print it out as part of his script.
