This command line tool, yt, can be used to run the entire YAML-Tests suite against a particular Perl YAML implementation.

yt is basically a wrapper around prove. As such, it accepts and passes along prove command line options. The main difference is that it knows where the YAML-Tests live and how to set up the environment to run them.


yt relies on two environment variables:


This variable should be set to the absolute pathname of the directory containing the contents of the YAML-Tests module distribution.

You can get YAML-Tests from CPAN or its SVN repository:

This variable conatins the name of the Perl YAML module you want to test. It can be set as an environment variable, but is normally passed to yt by the -M flag:

    yt -MYAML::Syck
