On the Laravel News site they've posted a guide showing you how to setup and run PHPUnit tests from Sublime Text, one of the more popular editors for code development.
Sublime Text is a great editor. It’s lightweight, fast, and extremely customizable. However, one downside to it compared to a full blown IDE is it doesn’t come with support for running your PHPUnit tests directly from the test class you are working with.To solve this problem, Adam Wathan created and released a free package named Sublime PHPUnit that allows you to run your tests from a keyboard shortcut. Let’s take a look at how to add this package to your arsenal.
The post walks you through the installation of the tool (manually cloning the repository) and how to then use it via Sublime's command palette. There's also some instruction on customizing the plugin's setup and allowing for shortcut keystrokes bound to events the plugin provides. The final tip helps you change the tool used to run the tests (the Terminal app by default) over to something like ITerm.
