Why don't you run it from the command line? I found the IDE to be very slow. If you are using version 2.1.1, you can only use a simple rake. This will give you an interactive console and from there just run the test-app command. This will run your entire test. If you want to run a specific test, you can also do it, just look here and you will see how you can run a specific test
If you are using version 1.3, you can use the grails interactive command and this will give you an interactive console. You can use the same test application list to run all of your tests.
