TestNG + Selenium woes. noClassDef error, TestNG based selenium test

Question

Hello, I've followed a lot of the guides and forum posts online but haven't had any luck getting this to work inside TestNG. It's a selenium grid based test, programmed in eclipse. Had trouble, so used the libraries listed in the suggestion of this forum post: http://clearspace.openqa.org/message/66867

I am trying to run the suite in the testNG test plugin for eclipse (org.testng.eclipse). Also tried running the jar from command line through selenium grid to no avail.

Since I'm not a java developer, to be honest I'm not entirely sure what to look for. I've some familiarity with Java thanks to the Processing environment, but I've kind of been thrown into java/eclipse for this task and am at a bit of a loss. Anyway, any help is appreciated and thank you in advance.

Here's my code:

suite.java:

    package seleniumRC;
//import com.thoughtworks.selenium.*;
//import junit.framework.*;
//import java.util.regex.Pattern; 

//import static org.testng.AssertJUnit.assertTrue;
 //import org.testng.annotations.AfterMethod;
//import org.testng.annotations.BeforeMethod;
//import org.testng.annotations.Parameters;
import org.testng.annotations.Test;


public class suite extends Testcase1 {

@Test(groups = {"example", "firefox", "default"}, description = "test1")
    public void user1() throws Throwable {   
     testCase1();
    }

@Test(groups = {"example", "firefox", "default"}, description = "test2")
    public void user2() throws Throwable {

     testCase1();
    }

}

The actual test case

    package seleniumRC;

//import com.thoughtworks.selenium.*;
//import org.testng.annotations.*;
//import static org.testng.Assert.*;
//import com.thoughtworks.selenium.grid.demo.*;
//import junit.framework.*;
//import com.ibm.icu.*;
//import java.util.regex.Pattern; 

//import static org.testng.AssertJUnit.assertTrue;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Parameters;


public class Testcase1 extends SeleneseTestNgHelper {

 private static int $itter = 10;

 public static void main(String args[]) {
  //junit.textui.TestRunner.run(Suite());
 } 

//public static Test Suite() {
 // return new TestSuite(Testcase1.class);
 //}

// public void setUp() throws Exception {
//  setUp("http://localhost:8080/test", "*firefox");
 //}
 @BeforeMethod(groups = {"default", "example"}, alwaysRun = true)
     @Parameters({"seleniumHost", "seleniumPort", "browser", "webSite"})
     protected void startSession(String seleniumHost, int seleniumPort, String browser, String webSite) throws Exception {
         startSession(seleniumHost, seleniumPort, browser, webSite);
         selenium.setTimeout("120000");
     }

@AfterMethod(groups = {"default", "example"}, alwaysRun = true)
     protected void closeSession() throws Exception {
         closeSession();
     }


 public void testCase1() throws Exception {
  selenium.open("/login.action#login");
  selenium.type("userName", "foo");
  selenium.type("password", "bar");
  selenium.click("login");
  selenium.waitForPageToLoad("30000");
  selenium.click("link=test");
  Thread.sleep(4000);
  selenium.click("//tr[4]/td[1]/a");

  if(selenium.isElementPresent("//input[@id='nextButton']") != false){
  selenium.click("//div[2]/input");
  }
  Thread.sleep(2000);

  for(int i=0; i < $itter; i++) {
  if(selenium.isElementPresent("//label") != false){

    selenium.click("//label");
    selenium.click("submitButton");
    Thread.sleep(1500);
  }
  else{ Thread.sleep(1500);}
  }

   selenium.click("//body/div[2]/div[1]/div/a");
   Thread.sleep(1500);
   selenium.click("//a[contains(text(),'Finish Now')]");


  Thread.sleep(2000);
  selenium.click("link=View Results");
  Thread.sleep(30000);
  selenium.click("showAllImgCaption");
  Thread.sleep(12000);
  selenium.click("generateTimeButton");
  Thread.sleep(2000);
  selenium.click("link=Logout");
  selenium.waitForPageToLoad("15000");
 }
 }

Answer 1

So I solved this by dropping the seleniumTestNGHelper class and reworking the classpaths by way of the ant file. It required completely working my suite/original testcases, but worked well within Grid.
