Session Handling

Introduction

In Selenium, the TestNG framework is used to perform Session Handling with the help of the Selenium web driver. We use the parallel attribute in the TestNG XML file to trigger parallel sessions. All the configurations are added in the TestNG XML file. 

Another attribute, thread-count, is added to the TestNG XML file to specify the number of threads to be created while executing the tests in parallel mode. 

Example

In the following example, we will execute three different sessions with three different session IDs in parallel using Selenium.

parallelCode.java

import org.openqa.selenium.WebDriver;
import org.testng.annotations.Test;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.remote.SessionId;
public class parallelCode {
   @Test
   public void TestCase1 () {
      System.setProperty("webdriver.chrome.driver", "C:\\Users\\91963\\Desktop\\Java\\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      driver.get("URL To Test");
      //Fetch session ID
      SessionId s = ((RemoteWebDriver) driver).getSessionId();
      System.out.println("Session Id for the first method: " + s);
   }
   @Test
   public void TestCase2 () {
      System.setProperty("webdriver.chrome.driver", "C:\\Users\\91963\\Desktop\\Java\\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      driver.get("Second URL To Test");
      //Fetch session ID
      SessionId s = ((RemoteWebDriver) driver).getSessionId();
      System.out.println("Session Id for the second method: " + s);
   }@Test
   public void TestCase3 () {
      System.setProperty("webdriver.chrome.driver", "C:\\Users\\91963\\Desktop\\Java\\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      driver.get("Third URL To Test");
      //Fetch session ID
      SessionId s = ((RemoteWebDriver) driver).getSessionId();
      System.out.println("Session Id for the third method: " + s);
   }
}

TestNG XML implementation
