Selenium Grid -- Advanced: Running tests in multiple hosts with multiple browser

Step 1: Machine setup

1. Suppose  you have two machines:

Machine 1 IP is : 192. 168. 0. 100

Machine 2 IP is : 192. 168. 0. 101

 

Step 2: Start hub and nodes

In machine 1, we start the hub and a node.

hub

java -jar selenium-server-standalone-2.53.0.jar -role hub

 

IE node:

java -jar selenium-server-standalone-2.53.0.jar -Dwebdriver.ie.driver="<yourpath>/IEDriverServer.exe" -role 
     webdriver -hub http://localhost:4444/grid/register -browser browserName="internet explorer"

 

 

Note:

1) For IE webdriver, please download the corresponding version and bit against the selenium-server-standalone server and windows bit, for example, if you use selenium-server-standalone-2.53.0 in win7 64bit OS, you should download the IEDriverServer_x64_2.53.0.zip

2) Here is the URL: http://selenium-release.storage.googleapis.com/index.html

 

In machine 2, config the other two nodes:

For Firefox node:

java -jar selenium-server-standalone-2.53.0.jar -role webdriver -hub http://192.168.0.100:4444/grid/register -browser browserName=firefox

For Chrome node:

java -jar selenium-server-standalone-2.53.0.jar -Dwebdriver.chrome.driver="<yourpath>/chromedriver.exe" -role
    webdriver -hub http://192.168.0.100:4444/grid/register -port 6666 -browser browserName=chrome

 

Step 3: Write your test case

Write a test case with testng:

package testcases;
import java.net.MalformedURLException;
import java.net.URL;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;


public class GridParallelTests{
    private WebDriver dr;
    DesiredCapabilities dc; 
    String baseUrl; 
    
    @Parameters({"browser", "nodeUrl", "webSite"})
    @BeforeMethod
    public void setUp(String browser, String nodeUrl, String webSite){
        baseUrl = webSite;
        if(browser.equals("ie"))
            dc = DesiredCapabilities.internetExplorer();
        else if(browser.equals("ff"))
            dc = DesiredCapabilities.firefox();
        else if(browser.equals("chrome"))
            dc = DesiredCapabilities.chrome();
        else
            System.out.println("browser is wrong, only can be ie, ff, chrome");
        
        String url = nodeUrl + "/wd/hub";
        URL urlInstance = null;
        try{
            urlInstance = new URL(url);
        }
        catch (MalformedURLException e){
            e.printStackTrace();
            System.out.println("Error: Please check the url format, should be：http://");
        }
        dr = new RemoteWebDriver(urlInstance, dc);
        dr.get(webSite);
    }
    
    @Test
    public void test(){
        dr.get(baseUrl);
        dr.findElement(By.id("kw")).sendKeys("Hello Webdriver!");
        dr.findElement(By.id("su")).click();
        try{
            Thread.sleep(10000);
        }
        catch(InterruptedException e){
            e.printStackTrace();
        }
        System.out.println("title:" + dr.getTitle());
    }
    
    @AfterMethod
    public void quit(){
        dr.close();
    }
}

 

 Step 4: Config testng xml file

Write the testng xml file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite">
  <test name="Test1">
    <parameter name="browser" value="ff"/> 
    <parameter name="nodeUrl" value="http://machine1:5555"/> 
    <parameter name="webSite" value="http://www.baidu.com"/> 
    <classes>
      <class name="testcases.GridParallelTests"/>
    </classes>
  </test> <!-- Test -->
  <test name="Test2">
      <parameter name="browser" value="chrome"/> 
    <parameter name="nodeUrl" value="http://machine1:6666"/> 
    <parameter name="webSite" value="http://www.baidu.com"/> 
    <classes> 
        <class name="testcases.GridParallelTests"></class> 
    </classes> 
  </test>
  <test name="test3"> 
    <parameter name="browser" value="ie"/> 
    <parameter name="nodeUrl" value="http://machine2:5555"/> 
    <parameter name="webSite" value="http://www.baidu.com"/> 
    <classes> 
        <class name="testcases.GridParallelTests"></class> 
    </classes> 
  </test> 
</suite> <!-- Suite -->

 

 Step 5: Run test suite

In Eclipse, run the xml file as test suite:
