What does result.output contains if the test fails? Since both stdout and
stderr are redirected to a file, there might be nothing at all there?

I'd suggest you actually print all of summary.txt in case of failure (yes
it's over a megabyte, that is fine), and also point out where the file can
be found for further inspection.
