What It Does

The theme check plugin is an easy way to test your theme and make sure it's up to spec with the latest theme review standards. With it, you can run all the same automated testing tools on your theme that WordPress.org uses for theme submissions.

The tests are run through a simple admin menu and all results are displayed at once. This is very handy for theme developers, or anybody looking to make sure that their theme supports the latest WordPress theme standards and practices.

The Theme Review team use this plugin while reviewing themes and copy/paste the output into trac tickets. To enable trac formatting in Theme-Check you need to define a couple of variables in wp-config.php. If either of these two vars are defined a new trac tickbox will appear next to the Check it! button.
