To the best of my knowledge: Wrong. The shortest possible match is taken (or
was it the longest?) Anyway, testimony is matched as well.
I just tried this rule:
* ^Subject:.*TRi-spamtest
with a subject "TRi-spamtest xxx" and it matched.
If you want to be sure only "test" is matched, you'd have to use:
* ^Subject: +test$
$ stands for end of line, so this rule would match the word test with one or
more spaces in front of it and nothing after it.

No. The + is related to the space in front of it (hence " test" is
valid). test+ would filter "test", "testt", "testtt", ...
The + means "one or more of the characters/expressions in front of the +".
See e.g. man procmailrc for more.
BTW: grep works in a very similar way. It all boils down to regular
expressions. The procmailex man page refers to the egrep man page as well.
HTH,
