disable javascript for the whole project?

Hello!

I'm using the canoo webtest plugin for grails and I would like to 
disable java script for all tests.
The only thing I know is, that I can disable java script for each test 
by adding "enableJavaScript(enable: false)"

Example of a test class:

class MyTest extends extends grails.util.WebTest {

   def test1() {
      enableJavaScript(enable: false)
      invoke(url:"http://example.com/page1.html")
   }
   def test2() {
      enableJavaScript(enable: false)
      invoke(url:"http://example.com/page2.html")
   }
}



Is there any way to disable javascript for all tests in a project? Is 
there any option I could write to the webtest.properties?

kind regards
     Franz
