Precision testing for modern perl
TestModern provides the best features of TestMore, TestFatal, TestWarnings, TestAPI, TestLongString, and TestDeep, as well as ideas from TestRequires, TestDescribeMe, TestMoose, and TestCleanNamespaces.
TestModern also automatically imposes strict and warnings on your script, and loads IOFile. Much of the same stuff ModernPerl does.
Although TestModern 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.
