Sebastian Bergmann: Using PHPUnit from a PHP Archive (PHAR)
PHPUnit, the popular PHP unit testing tool, has undergone some changes in its methods of deployment. First it was integrated into the Composer/Packagist dependency management system and now it's been implemented as a phar archive. Sebastian Bergmann explains how to use it in his latest post.
Downloading a single file to use PHPUnit? Not an idea that is too phar out anymore! Starting with version 3.7.5, PHPUnit seems to finally work correctly when packaged as a PHP Archive (PHAR).
He includes a list of steps you can follow to pull down the latest code and use the phar branch that executes with the archive file instead of the local "phpunit" executable. Of course, you can still (as always) install PHPUnit via the PEAR process as well.
