Using Selenium Test case in Grails

[Goran Markovic]

Greets everyone,
I have following requirement. I need to do with Selenium IDE, the Groovy classes which are exported when testing is done.
Something like this :

package com.example.tests

import com.thoughtworks.selenium.*

class Test extends GroovySeleneseTestCase {

    @Override
    void setUp() throws Exception {
        super.setUp('http://change-this-to-the-site-you-are-testing/', '*chrome')
        setDefaultTimeout(30000)
        setCaptureScreenshotOnFailure(false)
    }

    void test() throws Exception {
        selenium.open("/Checking+Projects+into+SVN")
        selenium.clickAndWait("link=Quick Start")
        selenium.click("link=Configure a Data Source (Optional)")
        selenium.clickAndWait("link=Checking Projects into SVN")
        verifyTrue(selenium.isTextPresent("x) but makes the followi"))
    }
}

To be honest, I do not know what to do with this class?! Where to place (I have read it should be in - grails-app/selenium/tests folder. is that correct?), and how to use it, how to perform testing with it? Please, any directive if not answer will be helpful
Thanks in advance on your answers !
