Directories under t and prove
t/ other.t something.t win32/ ui.t
prove t/*.t prove -r recursively prove t/something.t t/something.t prove t/win32 t/win32/*.t
Even better to use the prove t/something.t command that comes with Test::More. It too by default would attempt to use the already installed modules so you could run prove -b t/something.t to include the files from blib/lib. Prove has another frequently used flag: -v which puts it in verbose mode.
