You're right. "clean" is failing to remove some of the testing residue
files. I just fixed that, I think.

Wouldn't it?

I think I took care of that.

Sure would!

No it doesn't. "test" is an abstract target like "all" or "exe", which
depends on a whole bunch of actual targets, namely all of the test results.
I've enclosed a listing of the commands executed when I build test, then
clean, then test again. I can't understand why it wouldn't be happening for
you, but you could look at the -d+12 output to see what decisions it's

It's documented in tools/buid/testing.jam only.

You're not a pest; I'll try to help.
