How To Delete Cookies In Selenium

In this tutorial, I will tell you how to delete cookies -

1. We need to create an object of cookie and pass the cookie name and value to the cookie's constructor as an argument.

2. Add cookie using selenium webdriver.

3. Now delete cookies using selenium webdriver.

Let's See The Example

import java.util.Set;

import org.openqa.selenium.Cookie;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Training {

 public static void main(String[] args) throws InterruptedException {

  WebDriver driver = new FirefoxDriver();

  driver.navigate().to("http:// www.flipkart. com/");

  Cookie name = new Cookie("mycookie", "12345");
  driver.manage().addCookie(name);

  // Let's get the cookie's value
  Set<cookie> cookies = driver.manage().getCookies();
  for (Cookie getcookies : cookies) {
   System.out.println(getcookies);
  }

  /*
   * You can delete cookies in 3 ways 1. By name
   * driver.manage().deleteCookieNamed("CookieName");
   * 
   * 2. By Cookie driver.manage().deleteCookie(getcookies);
   * 
   * 3. All Cookies driver.manage().deleteAllCookies();
   */
  driver.manage().deleteAllCookies();

How To Switch Between Multiple Windows

Web page may have multiple windows. Multiple windows means a link on a web page of another web page. Current web page is called main window and other windows called child window.

Each window has its own unique alphanumeric id. Selenium WebDriver uses this unique id to switch control between multiple windows.

How To Switch Between Multiple Windows

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Training {

 public static void main(String[] args) throws InterruptedException {

  WebDriver driver = new FirefoxDriver();
  driver.get("http://reditblog.blogspot.in/p/selenium.html");
  driver.manage().window().maximize();
  Thread.sleep(5000);
  String mainWindow = driver.getWindowHandle();

  WebElement element = driver
    .findElement(By
      .linkText("Org.Openqa.Selenium.Firefox. NotConnectedException"));

  element.click();

  Thread.sleep(5000);
  for (String windowHandle : driver.getWindowHandles()) {
   if(windowHandle.equals(mainWindow)){
    System.out.println("Main Window - " + " "+ windowHandle);
    driver.switchTo().window(windowHandle);    
    System.out.println(driver.getTitle());
    
   }else{
    System.out.println("Child Window - " + " "+ windowHandle);
    Thread.sleep(5000);
    driver.switchTo().window(windowHandle);
    Thread.sleep(5000);
    System.out.println(driver.getTitle());
    driver.switchTo().defaultContent();   
    
   }
   
  }
