We are having a testing hackathon for our opcodes! These tests are t/op/*.t in the Parrot repo. This event has been added to Calagator to let people know about it: http://calagator.org/events/1250458003 Here are some guiding principles of the hackathon: * In general, improving coverage is better than converting tests to PIR, but both are valuable * To increase coverage: * find an untested op and write tests for it * find an undertested op and write more tests for it * for help with either, ask on #parrot for assistance! * If there are tests written in Perl, we would like to convert them to PIR, if possible. * Some can't be converted because the required testing functions do not exist in Parrot's Test::More * In this case, improve Test::More * Some advanced testing functions are not available yet, like eq_or_diff . These would be really awesome to have! * Add tests for things with the lowest coverage first * If you want to add tests to a large, currently Perl 5 test file, svn copy the foo.t to foo-old.t, then start writing PIR tests in foo.t and migrating tests from foo-old.t to foo.t as tests are translated
