This is my idea (disable logging on the ant level).
This is how it looks now when everything goes well:
{noformat}
$ ant beast -Dbeast.iters=10 -Dtestcase=TestVersion
[...]
-init-totals:
-beast:
[beaster] Beast round: 1
[beaster] Beast round: 2
[beaster] Beast round: 3
[beaster] Beast round: 4
[beaster] Beast round: 5
[beaster] Beast round: 6
[beaster] Beast round: 7
[beaster] Beast round: 8
[beaster] Beast round: 9
[beaster] Beast round: 10
[beaster] Beasting finished.
-check-totals:
beast:
BUILD SUCCESSFUL
Total time: 23 seconds
{noformat}
Unfortunately this is how it looks when it goes wrong:
{noformat}
$ ant beast -Dbeast.iters=10 -Dtestcase=TestVersion -Dtests.codec=foobar
[...]
-init-totals:
-beast:
[beaster] Beast round: 1
BUILD FAILED

As you see, you get no idea what was wrong, nor get you a tests.seed on
failure. This looks like caused by junit4 not logging the error messages with a
log level of at minimum WARN, which you explained. Maybe all System.err stuff
should be printed with error log level.

> Currently, this outputs way too much, e.g. including all test output for
> every passing run (because this is the behavior when -Dtestcase is set).
> Especially with tests.verbose, this is really annoying as you have output
> from say 200 runs that you don't care about.
> I think ant beast should only show the interesting output for the failing run
> and try to suppress unnecessary output as much as possible for passing ones
> (it should be JUST enough to know your test ran and passed and not ignored,
> e.g. you didnt screw up).
