It's not just getting @INC right. The tests must be run from t/ (ie. a canonical directory they're always run from) so that they can find certain files properly and so that they only scribble scratch files inside t/. For example, lib/Test/Simple/t/exit.t has to find some sample programs to test against in t/lib/Test/Simple/sample_tests. How can it find it if it doesn't know where it was run from? You have to get into things like looking at $0 and trying to walk your way up to the top level source directory. Icky. The existing t/TestInit.pm takes this into account by simply chdir'ing to t/. -- Michael G.
