For the PHP developers among us who test their code using PHPUnit, Sublime has an awesome plugin to support PHPUnit known as sublime-phpunit, written by Stuart Herbert and located at http://github.com/stuartherbert/sublime-phpunit.
If you are a PHP developer and do not know what PHPUnit is, you should learn that PHPUnit is "the standard" for unit testing in PHP projects. It combines a framework that lets us easily write and run tests with the facility to analyze the results.
We can learn more about PHPUnit at https://github.com/sebastianbergmann/phpunit/ or check the full manual at http://phpunit.de/manual/current/en/index.html.
