Running functional tests with Xephyr

Xephyr.groovy

includeTargets << grailsScript("_GrailsInit")

display = ':65'
resolution = '-screen 1024x768'

target('default': "Run tests with xephyr") {

    List parsedArgs = args.split() as List

    exec (executable: 'Xephyr', spawn: true) {
        arg(line:display)
        arg(line:resolution)
    }
    event("ExecCommand", ['env', ["DISPLAY=${display}", 'grails']+parsedArgs, 'Xephyr Failed: Could not execute task in embedded X display'])
    exec (executable:'killall') {
        arg(line:'Xephyr')
    }

}

Running grails functional tests with Xephyr.

The reason you'd want to run with Xephyr is so that your functional tests never lose focus, you can continue using the machine whilst your test suite runs.

sudo apt-get install xephyr

then place this file into your grails app's scripts directory, and prefix any targets you use with 'xephyr' - i.e:

grails xephyr test-app

this is awesome, thanks

It's seems to solve the same thing that textbox by @doktor500 and @mgryszko with a different approach.

Did you try vnc4server? I think it does the same (adds a headless X server), but it allows you to connect with VNC to the server. You can watch tests being executed and record them.
