and maintainer of:
I have had several experiences where my unit-test suite passes, but Devel::Cover fails. I use the testcover target from Module::Build, but experienced the same problem when calling Devel::Cover in the conventional way.
I found this thread about the problem. But I am not complete convinced on how to proceed.
After getting test coverage to 98.6% on Business::OnlinePayment::CashCow I wanted to get high coverage on Date::Holidays aswell, since I was working on an update of this module.
This is the trouble some part
t/is_holiday......ok 11/12# Looks like your test died just after 12.
Test returned status 255 (wstat 65280, 0xff00)
after all the subtests completed successfully
Test 12, is the final test and nothing happens after that test - and the problem is probably in the actual module - hmmm...
