How do you do remote service tests in IJ

How do you do async tests in IJ if you can't specify the tests to run in the browser with the http address?

This works fine in FB4 where the test runs fine in the browser with the specific url, in IJ it just uses the path to the file ie e:/app/test

package services
{
    import flexunit.framework.Assert;
    
    import mx.rpc.AsyncResponder;
    import mx.rpc.AsyncToken;
    import mx.rpc.events.FaultEvent;
    import mx.rpc.events.ResultEvent;
    
    import org.flexunit.async.Async;
    
    import services.AuthenticationService;
    
    public class AuthenticationServiceTest
    {        
        
        private var objectToTest:AuthenticationService
        
        [Before]
        public function setUp():void
        {
            objectToTest = new AuthenticationService;
        }
        
        [After]
        public function tearDown():void
        {
            
        }
        
        [BeforeClass]
        public static function setUpBeforeClass():void
        {
            
        }
        
        [AfterClass]
        public static function tearDownAfterClass():void
        {
        }
        
        [Test(async)]
        public function testAttemptLogin():void
        {
            var token: AsyncToken = objectToTest.attemptLogin('k','sd');
            token.addResponder(Async.asyncResponder(this, new AsyncResponder(onResult, faultHandler), 1300));
        }
        
    
        private function onResult(event:ResultEvent,pass:Object):void {
            
            Assert.assertEquals('Sucessful login',event.result.length ,1);
            
        }
        
        
        private function faultHandler(event:FaultEvent,pass:Object):void
        {
            
            Assert.fail("service Fail");
        }
    
    }
}
