i was thinking something like this:
Random rand = new Random();
upperLimit = 4;
icnt = rand.nextInt(upperLimit);
switch (icnt)
{
case 0:
WebUI.click(findTestObject('Inbox'))
break;
case 1:
WebUI.click(findTestObject('LC 4/27'))
break;
case 2:
WebUI.click(findTestObject('DC 2/13'))
break;
case 3:
WebUI.click(findTestObject('BG 1/5'))
break;
default:
WebUI.comment("Whoops")
break;
}
