One step ahead of you. Have a look at Test::Simple and Test::More.
They introduce the idea of test names, short descriptions of each
test. The numbers become little more than bookkeeping.
use Test::Simple tests => 3;
ok( $this eq 'that', 'this is that' );
ok( Some::Class->can('bar'), 'Some::Class->bar() exists');
ok( @stuff, 'got some stuff');
produces
1..3
ok 1 - this is that
ok 2 - Some::Class->bar() exists
ok 3 - got some stuff
now you can stick a test in anywhere and find it quickly from its name.
Test::Simple is a candidate for the core once its interface has
solidified a bit more.

Please no, the test files will become an incomprehensible mess with no
rhyme or reason if we just start chucking things at the end. Try to
keep similar tests grouped.
