it's too verbose. all the "" and :: and * and ** and Comment and so
forth. just using intelligent whitespacing. the other stuff just makes
me glaze over immediately.

i want summary output at the console and detailed trace info in a log.
can it do that?

i'd rather not see this in my console. i'd rather grep through a log file.

i don't want the test tool filling 800 lines of scrollback buffer if
i'm only going to look at the final 3 lines. just show me a list of
names of tests that failed so that i can find them in the log to look
at their stack traces.

both, and i disagree. the time elapsed for the test suite and failed
tests are not needed to understand what failed. only the failing
test's names.

when i look at my console, i want to see that every test has been run
and which ones have failed. my original suggestion achieves this
admirably. fwiw, it is the standard format (maybe with a tweak or two)
for perl's test harness which has been in use for ten plus years.

that is way too much information. how about:

TestBlah ... ok
Test2Blah ... failed ("this is the reason the test failed")

see how much more compact that is, and how it communicates exactly the
same info in 2 lines instead of 5, and how it's extremely easy to pick
out the failure when scanning the console's scrollback?
