I use Test::Unit::Lite for unit testing in Perl. Now, this module looks for .pm files in t/tlib. However, I have several tests for the project and I would like to separate them in folders like: t/tlib/Unit_Tests/...pm, t/tlib/Functional_Tests/...pm and so on.
How can I tell to the unit test module to look for files in subdirectories of t/tlib. Right now, if I make some directories there, it just ignores them.
