Using Selenium Grid with Two Nodes-FF & Chrome(HUB)

6:35 AM 1 Comments

1. Download the Selenium Sever Jar File using the link

http://selenium-release.storage.googleapis.com/2.45/selenium-server-standalone-2.45.0.jar

2. Pre-requisite for Every Machine 

Copy  the Selenium Server in every host hub,remote node1,remote node2

3. To check the default port number used by Hub '4444' is reserved or not

Command --> netstat -a -n | findStr 4444

We have to check this command only in hub machine.

4. Starting the Hub. Navigate to the location where the selenium-server jar is downloaded and execute the below command.

java -jar selenium-server-standalone-2.44.0.jar  -role hub

5. Starting the Hub using particular port. If the default port '4444' is already in use. Then we have to pass another port number in the command line for the argument -port as mentioned below:

java -jar selenium-server-standalone-2.44.0.jar  -role hub -port 4545

6. Verifying the Hub Console

http://localhost:4444/grid/console

7.Starting Node1: Navigate to the location where selenium server jar is located and execute the below command

java -jar selenium-server-standalone-2.44.0.jar  -role webdriver -browser "browserName=firefox,version=35,maxInstances=1,platform=WINDOWS" -hubHost localhost -port 4546

8. Starting Node2: Navigate to the location where selenium server jar is located and execute the below command

java -jar  selenium-server-standalone-2.44.0.jar -role webdriver -browser "browserName=chrome,version=40,maxInstances=1,platform=WINDOWS" -hubHost localhost -port 4547 -Dwebdriver.chrome.driver=D:\\Selenium\\chromedriver_win32\\chromedriver.exe 

9. Selenium WebDriver Script for FF

DesiredCapabilities caps = new DesiredCapabilities();

caps.setBrowserName("firefox");

caps.setVersion("35");

caps.setPlatform(Platform.WINDOWS);

RemoteWebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),caps);

10. Selenium WebDriver Script for CH

 DesiredCapabilities caps = new DesiredCapabilities();

caps.setBrowserName("chrome");

caps.setVersion("40");

caps.setPlatform(Platform.WINDOWS);

RemoteWebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),caps);

System.out.println("in FF");
//driver =new FirefoxDriver();
}

System.out.println("in CH");
}
driver.get(url);
}

{

Assert.assertEquals(driver.getTitle(),"Facebook");
