How do I test individual protractor tests in grails?

[iggyGrande]

I was religiously following icodeya's tutorial about incorporating protractor tests in my grails application. It works really well. I was wondering if there is a way for me to make a similar command for testing an individual protractor test file? Like: grails protractor someTest or something? Is that even possible? This is the entire file:

includeTargets << grailsScript("_GrailsRun")
includeTargets << grailsScript("_GrailsClean")
includeTool << gant.tools.Execute
 
target(default: "Run all protractor tests.") {
 
    depends(clean, configureProxy, checkVersion, parseArguments, compile, packageApp)
 
    runApp()
    println 'Running grails app now...'
 
    def process = "protractor PATH/TO/config-e2e.js".execute()
    process.waitFor()
 
    println process
    println process.exitValue()
    println process.in.text
    println process.err.text
 
    println 'Shutting down the server...'
    stopServer()
 
    execute.shell("grails clean")
    print 'Done with protractor tests...'
}
