Selenium Webdriver 7 - Browser manage function "Cookies"

Session highlights 

• The brief theory about cookies.
• How to see existing cookies.
• how to add cookies.
• how to delete cookies

1. What is a cookie ?

Ans : Cookies are usually small text files.

2. When Cookie file is created?

Ans : Cookies are created when you use your browser to visit a website

3. What cookie file contains?

Ans : "key = value" pair . For ex : "domain=127.0.0.1"

4. What is the use of cookie?

Ans: This is an interesting question. Let's consider below scenarios. 

Scenario 1:

>Open browser.

> type www.google.com and press enter.

> search "Mother Teresa" press enter.

>click on the back button on the browser.

>Now observe page reload the google home page ....! - It means someone is tracking our path.

Scenario 2:

>Open browser.

>Go to gmail website.

>Enter login credentials.

>Click on remember password   ....! - It means someone is remembering.

Thats all ! From above two scenario you might be understood what cookie file contains.

Program:

package shirageri.blog;

import java.util.Set;

import org.openqa.selenium.Cookie;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

public class BrowserManage1 {

public static void main(String[] args)

{

String URL = "http://127.0.0.1:88/login.do";

WebDriver driver = new FirefoxDriver();

driver.get(URL);

//Step 1 - Adding cookies 

Cookie cookie = new Cookie("COOKIE_NAME", "Cookie_Value");

driver.manage().addCookie(cookie);

//Step 2 - Displaying cookies

Set<Cookie> cookiesList =  driver.manage().getCookies();

for(Cookie getcookies :cookiesList) 

{

   System.out.println(getcookies );

}

System.out.println("------------------------------");

//Step 3 - Deleting added cookie

driver.manage().deleteCookie(cookie);

//Step 4 - Check deleted cookie is not shown

cookiesList =  driver.manage().getCookies();

for(Cookie getcookies :cookiesList) 

{

   System.out.println(getcookies );

}

System.out.println("------------------------------");

         //Step 5 - Delete all cookies

driver.manage().deleteAllCookies();

}

}

Note : In step 3 from above program we can also use "deleteCookieNamed()" method to delete by passing cookie name as argument. For ex:

driver.manage().deleteCookieNamed("COOKIE_NAME");
