Thank you. `rackunit/text-ui' looks interesting and I'll investigate it.

My backup plan is to write a filter that will wrap around `raco test
...'. It will then output everything `raco test ...' outputs but will
heuristically look for failures, like the word "FAILURE" or the phrase
"Check failure", returning non-0 values accordingly.
