Bug #20970 for YAML-Syck: A variety of things are not compatible with YAML.pm

Sun Aug 13 08:33:18 2006 adamk [...] cpan.org - Ticket created

Subject:

A variety of things are not compatible with YAML.pm

The test suite for YAML::Tiny now tests not only compatibility with YAML.pm but also with YAML::Syck. It's thrown up half a dozen cases where Syck doesn't match YAML.pm. To see them all, grab the latest YAML::Tiny and enable the YAML::Syck testing in t/lib/MyTests.pm. I've commented them out for now, until they work. Adam K

This needs review after 1.11 goes in.

I have a proposal. Right now we're cross-certifying YAML and JSON modules. I think this is the wrong approach. What's needed is 2 CPAN modules: Test::YAML::Spec qw($yaml_module_name) and Test::JSON::Spec qw($json_module_name); The modules would be responsible for testing all of the known spec in each direction. We could store these tests in Data::Dumper format if needed, along side their expected output. What do you think? Todd

I think you are underestimating what it would take to test "all" of the YAML specification. As for YAML::Tiny, it isn't there to test compatibility with the YAML specification. It's there to test only the subset that it supports. Writing a compliance test for JSON may well be possible though. I'm not sure how you'd define the tests for things like boolean true and false though, which Perl doesn't support. Adam K On Mon Jul 19 18:24:15 2010, TODDR wrote: Show quoted text

You could have an annotated YAML test suite, so that e.g. there was a t/yaml-tiny/ part of it that would be the only part you would import, but others would test the rest (including YAML::Tiny). It could work similarly to how the Perl 6 "fuzz" tests work, where multiple implementations are being tested with the same test suite using annotations. There would be a lot of value in doing something like that.
