Hi All, I'm researching Selenium and have a seminar for my group... I meet many troubles with this I use C# language and write a demo SeleniumExample.dll Then i start selenium RC and NUnit and run it with nUnit to see the test report. I read testdata from xml. Here's the SeleniumExample.dll: using System; using System.Xml; using System.Text; using System.Text.RegularExpressions; using System.Threading; using NUnit.Framework; using Selenium; namespace SeleniumExample { public class Success_Login { //User defined private string strURL = "http://newtours.demoaut.com/ mercurywelcome.php"; private string[] strBrowser = new string[3] { "*iehta", "*firefox", "*safari" }; // System defined private ISelenium selenium; private StringBuilder verificationErrors ; [SetUp] public void SetupTest() { selenium = new DefaultSelenium("localhost", 4444, this.strBrowser[0], this.strURL); selenium.Start(); verificationErrors = new StringBuilder(); } [TearDown] public void TeardownTest() { try { selenium.Stop(); } catch (Exception) { // Ignore errors if unable to close the browser } Assert.AreEqual("", verificationErrors.ToString()); } [Test] public void Success_LoginTest() { try { XmlDocument doc = new XmlDocument(); XmlNode docNode; doc.Load("XMLFile1.xml"); docNode = doc["TestCase"]; foreach (XmlNode node in docNode) { selenium.Open("/"); selenium.Type("userName", node["username"].InnerText); selenium.Type("password", node["password"].InnerText); selenium.Click("login"); selenium.WaitForPageToLoad("30000"); Assert.AreEqual("Find a Flight: Mercury Tours:", selenium.GetTitle()); } } catch (AssertionException e) { verificationErrors.Append(e.Message); } } } } Now I wan to have a demo that using Selenium Grid (SG) but i dont know how to do. I read document and understand the way SG works. I install SG and install Ant1.8. The tests will communicate with Selenium Hub. Actually, I just understand the theory i dont know how to make the tests communicate with Selenium Hub and how to make Selenium Hub control Selenium RC. I am a new for Selenium. If anyone know this, please help me. I appreciate it so much. THANKS, Hoang
