|246||246||''Details'': Math::Primality is a Perl 5 CPAN module that has advanced prime-checking algorithms. It was a GSoC project in 2009. Currently some new algorithms were added, but they don't have proper test coverage. Having better test coverage is necessary because people will rely on the correctness of the algorithms in this module for cryptography and number theory applications. This task will involve the student learning how to build and test Math::Primality, as well as analyzing the test coverage with the Devel::Cover CPAN module. When parts of the code are identified that need more tests, the students will work with the mentor to write tests that verify those parts of the code work correctly.
