Looking at the tickets for Test::More I see it's mostly down to wishlist items and unimportant things. http://rt.cpan.org/Public/Dist/Display.html?Name=Test-Simple
I can identify only two real important bugs, as far as I'm concerned. The first has to do with overloading. cmp_ok() doesn't DTRT with overloaded operators and is_eq() can explode in certain edge cases. I tried fixing this once and it's pretty tricky. http://rt.cpan.org/Ticket/Display.html?id=24186 http://rt.cpan.org/Ticket/Display.html?id=20940 The other is a pile of bugs having to do with how Test::Builder detects if the test died. This should be pretty easy to fix and eliminates the troublesome $SIG{__DIE__} handler. http://rt.cpan.org/Ticket/Display.html?id=30081 http://rt.cpan.org/Ticket/Display.html?id=25294 http://rt.cpan.org/Ticket/Display.html?id=12359 Otherwise, what's important to people? I know there's a lot of suggestions about increasing the flexibility of planning. Also the oft requested "I'm done running tests" sentinel for a safer "no_plan". Most of the time I'm just wibbling over interface details, getting the names just right. (What! Argue over tiny interface issues? The Deuce you say!) -- Stabbing you in the face so you don't have to.
