Comment 2 for bug 1232077

IMO, the correct behaviour should be that passing tests only retrieve stdout while failures capture both stdout and stdin.

I'm sure checkbox already caches these somehow, so that it can grab the appropriate one for the results, so should be a matter of maybe either concatenating them for failures, or simply changing the output to look something like this for failed tests:

STDOUT:
soem stuff here
more stuff
usual suff
lots o output

STDERR:
error message
more error messages

The problem there is that it's possible the error messages will appear out of sync with the non-error output.

The only way I can think of to solve that would really be to dump them together at the test level and just grab them all, or do something like this:

each line of output would become a tuple in an ordered list:

1:(stdout,'something')
2:(stdout,'something more')
3:(stderr,'error message')
4:(stdout,'more output')

then when the result is collected, they can be replayed in order and for failures, grab all, and for pass, ignore anything with stderr in the tuple...

though that may be too complex an answer.,..
