Check syntax, presence of use strict; and test coveragehttp://search.cpan.org/dist/Test-Strict/
The most basic test one can write is "does it compile ?". This module tests if the code compiles and play nice with 'Test::Simple' modules.
Another good practice this module can test is to "use strict;" in all perl files.
By setting a minimum test coverage through 'all_cover_ok()', a code author can ensure his code is tested above a preset level of *kwality* throughout the development cycle.
Along with the Test::Pod, this module can provide the first tests to setup for a module author.
