Is there any integration of PHPUnit with Eclipse PDT?
If not, are there any plans to do so?
It is possible to integrate PHPUnit with PDT in a simple way (these settings aren't fully generic but should be a good starting point).
Now select Run > External Tools > PHPUnit to execute the selected test file. This simply executes phpunit and sends STDOUT to the Eclipse terminal. Simple but effective.
Subsequently, you can use the icon with a green arrow and red toolbox to run PHPUnit without having to navigate the menus.
