Having to count tests is annoying for maintainers. Also, manually updating count tests is problematic when multiple people are working on the same code; it causes merge conflicts and recounts. done_testing() is available since Test::More 0.88 which was released in 2009. This commit changes all tests under lib/ that use Test::More and were planning the number of tests. Michiel Beijen is now a Perl author
