devel/p5-Test-Modern - The NetBSD Packages Collection

Test::Modern provides the best features of Test::More, Test::Fatal,
Test::Warnings, Test::API, Test::LongString, and Test::Deep, as well as
ideas from Test::Requires, Test::DescribeMe, Test::Moose, and
Test::CleanNamespaces.

Test::Modern also automatically imposes strict and warnings on your script,
and loads IO::File. (Much of the same stuff Modern::Perl does.)

Although Test::Modern is a modern testing framework, it should run fine on
pre-modern versions of Perl. It should be easy to install on Perl 5.8.9 and
above; and if you can persuade its dependencies to install (not necessarily
easy!), should be OK on anything back to Perl 5.6.1.
