Test::More is a unit testing module for Perl. Created and maintained by Michael G Schwern with help from Barrie Slaymaker, Tony Bowden, chromatic, Fergal Daly and perl-qa. Introduced in 2001 to replace Test.pm, Test::More simplified and re-energized the culture of testing in Perl leading to an explosion of new testing modules and a strongly test driven community.Test::More is the most popular Perl testing module, as of this writing about 80% of all CPAN distributions make use of it.
