Shortcut: Ctrl + Alt + U, U

Features:

• Supports multiple cursors
• Can insert test methods based on the current cursor(s) lines contents. Will update method if shortcut is triggered from inside a docblock comment that's followed by a "public function test______" string
• Uses the project's indent settings; defaults on four spaces.

Limitations / bugs:

• no PHP-only file filtering was set, will trigger and behave the same for any file

Features under way:

• setup multiple tests sets (unit, integration), to be used by the file generator and configurable in each
• display editor gutter icon with link to the method's test file(s)
• create test file for a method or for a class

Install: Open PhpStorm's File / Settings... menu, go to Plugins and click the "Install plugin from disk..." button. Search for the jar file (download from the Releases page), click OK and restart the editor.

Check out the SublimeText or Eclipse versions of the plugin. Feel free to submit bugs or feature requests.
