Good day, I was trying to setup a PHP 5.x devt environment and was planning to have PHPUnit for unit testing purposes and other test-driven devt tasks, so I installed pear-PHPUnit2 package. However when I tried to run PHPUnit, it doesn't work, there isn't even a CLI command for it. Can somebody please advise me how to go forward with this? Thank you very much and have a great day.
