PHP Unit testing [closed]
Actually here is a list of all the common PHP unit testing frameworks.
I think you will find that the testing frameworks themselves have little interest in developing fancy GUIs. There is however several third party tools/applications/plugins that you can checkout. I use the phpunit integration within Netbeans a lot, and it works very good.
The requirement that it be
not command line based
is curious. In traditional PHP development you make an edit, load a webpage in your browser, and repeat. Instead, you can make an edit, run a piece of your test suite at the command line, then repeat. I have discovered the latter practice is usually much faster.
