Do you mean Test::Harness? If not, I'm confused (and I wrote a few pieces of Test::More. If so, then whatever happens when you type make test is important. It probably launches a program which uses T::H which launches your tests... but I can't guarantee that without seeing your Makefile. If that is the case, then you need to modify that code to pass arguments to your test files.

However, if this were my project, I'd remove all traces of interactivity from the tests, as you lose the prime benefit of automated tests if you remove automation. It's okay to use separate, manual tests as long as you're clear that they're separate and manual.
