Back in February I did a presentation for the Birmingham Perl Mongers, regarding a chunk of code I had been using to test websites. The code was originally based on simple XHTML validation, using the DTD headers found on each page. I then expanded the code to include pattern matching so I could verify key phrases existed in the pages being tested. After the presentation I received several hints and suggestions, which I've now implemented and have set up a GitHub repository.

Since the talk, I have now started to add some WAI compliance testing. I got frustrated with finding online sites that claimed to be able to validate full websites, but either didn't or charged for the service. There are some downloadable applications, but most require you to have Microsoft Windows installed or again charge for the service. As I already had the bulk of the DTD validation code, it seemed a reasonable step to add the WAI compliance code. There is a considerable way to go before I get all the compliance tests that can be automated written into the distribution, but some of the more immediate tests are now there.

As mentioned in my presentation to Birmingham.pm, I still have not decided on a name. Part of the problem being that the front-end wrapper, Test::XHTML, is written using Test::Builder so you can use it within a standard Perl test suite, while the underlying package, Test::XHTML::Valid uses a rather different approach and does provides a wider API than just validating single pages against a DTD specification. Originally, I had considered these two packages should be two separate releases, but now that I've added the WAI test package, I plan to expose more of the functionality of Test::XHTML::Valid within Test::XHTML. If you have namespace suggestions, please let me know, as I'm not sure Test-XHTML is necessarily suitable.

Ultimately I'm hoping this distribution can provide a more complete validation utility for web developers, which will be free to use and will work cross-platform. For those familiar with the Perl test suite structure, they can use it as such, but as it already has a basic stand-alone script to perform the DTD validation checks, it should be usable from the command-line too.

If this sounds interesting to you, please feel free to fork the GitHub repo and try it out. If you have suggestions for fixes and more tests, you are very welcome to send me pull requests. I'd be most interested in anyone who has the time to add more WAI compliance tests and can provide a better reporting structure, particularly when testing complete websites.
