Working with cookies
A cookie is a small piece of data that is sent from a website and stored in your computer. Cookies are mostly used to recognise the user and load the stored information.
WebDriver API provides a way to interact with cookies with built-in methods:
Add Cookie
It is used to add a cookie to the current browsing context. Add Cookie only accepts a set of defined serializable JSON object. Here is the link to the list of accepted JSON key values
First of all, you need to be on the domain that the cookie will be valid for. If you are trying to preset cookies before you start interacting with a site and your homepage is large / takes a while to load an alternative is to find a smaller page on the site (typically the 404 page is small, e.g. http://example.com/some404page)
driver.get("https://www.selenium.dev/selenium/web/blank.html");
// Add cookie into current browser context
driver.manage().addCookie(new Cookie("key", "value")); driver = webdriver.Chrome()
driver.get("http://www.example.com")
# Adds the cookie into current browser context
driver.add_cookie({"name": "key", "value": "value"}) driver.Url="https://www.selenium.dev/selenium/web/blank.html";
// Add cookie into current browser context
driver.Manage().Cookies.AddCookie(new Cookie("key", "value"));require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome
begin
driver.get 'https://www.example.com'
# Adds the cookie into current browser context
driver.manage.add_cookie(name: "key", value: "value")
ensure
driver.quit
end
await driver.manage().addCookie({ name: 'key', value: 'value' });import org.openqa.selenium.Cookie
import org.openqa.selenium.chrome.ChromeDriver
fun main() {
val driver = ChromeDriver()
try {
driver.get("https://example.com")
// Adds the cookie into current browser context
driver.manage().addCookie(Cookie("key", "value"))
} finally {
driver.quit()
}
}
Get Named Cookie
It returns the serialized cookie data matching with the cookie name among all associated cookies.
driver.get("https://www.selenium.dev/selenium/web/blank.html");
// Add cookie into current browser context
driver.manage().addCookie(new Cookie("foo", "bar"));
// Get cookie details with named cookie 'foo'
Cookie cookie = driver.manage().getCookieNamed("foo"); driver = webdriver.Chrome()
driver.get("http://www.example.com")
# Adds the cookie into current browser context
driver.add_cookie({"name": "foo", "value": "bar"})
# Get cookie details with named cookie 'foo'
print(driver.get_cookie("foo")) driver.Url = "https://www.selenium.dev/selenium/web/blank.html";
// Add cookie into current browser context
driver.Manage().Cookies.AddCookie(new Cookie("foo", "bar"));
// Get cookie details with named cookie 'foo'
Cookie cookie = driver.Manage().Cookies.GetCookieNamed("foo");require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome
begin
driver.get 'https://www.example.com'
driver.manage.add_cookie(name: "foo", value: "bar")
# Get cookie details with named cookie 'foo'
puts driver.manage.cookie_named('foo')
ensure
driver.quit
end
// Get cookie details with named cookie 'foo'
await driver.manage().getCookie('foo').then(function(cookie) {
console.log('cookie details => ', cookie);
});import org.openqa.selenium.Cookie
import org.openqa.selenium.chrome.ChromeDriver
fun main() {
val driver = ChromeDriver()
try {
driver.get("https://example.com")
driver.manage().addCookie(Cookie("foo", "bar"))
// Get cookie details with named cookie 'foo'
val cookie = driver.manage().getCookieNamed("foo")
println(cookie)
} finally {
driver.quit()
}
}
Get All Cookies
It returns a ‘successful serialized cookie data’ for current browsing context. If browser is no longer available it returns error.
driver.get("https://www.selenium.dev/selenium/web/blank.html");
// Add cookies into current browser context
driver.manage().addCookie(new Cookie("test1", "cookie1"));
driver.manage().addCookie(new Cookie("test2", "cookie2"));
// Get cookies
Set<Cookie> cookies = driver.manage().getCookies();
for (Cookie cookie : cookies) {
if (cookie.getName().equals("test1")) {
Assertions.assertEquals(cookie.getValue(), "cookie1");
}
if (cookie.getName().equals("test2")) {
Assertions.assertEquals(cookie.getValue(), "cookie2");
}
} driver = webdriver.Chrome()
driver.get("http://www.example.com")
driver.add_cookie({"name": "test1", "value": "cookie1"})
driver.add_cookie({"name": "test2", "value": "cookie2"})
# Get all available cookies
print(driver.get_cookies()) driver.Url = "https://www.selenium.dev/selenium/web/blank.html";
// Add cookies into current browser context
driver.Manage().Cookies.AddCookie(new Cookie("test1", "cookie1"));
driver.Manage().Cookies.AddCookie(new Cookie("test2", "cookie2"));
// Get cookies
var cookies = driver.Manage().Cookies.AllCookies;
foreach (var cookie in cookies){
if (cookie.Name.Equals("test1")){
Assert.AreEqual("cookie1", cookie.Value);
}
if (cookie.Name.Equals("test2")){
Assert.AreEqual("cookie2", cookie.Value);
}
}require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome
begin
driver.get 'https://www.example.com'
driver.manage.add_cookie(name: "test1", value: "cookie1")
driver.manage.add_cookie(name: "test2", value: "cookie2")
# Get all available cookies
puts driver.manage.all_cookies
ensure
driver.quit
end
await driver.manage().getCookies().then(function(cookies) {
console.log('cookie details => ', cookies);
});import org.openqa.selenium.Cookie
import org.openqa.selenium.chrome.ChromeDriver
fun main() {
val driver = ChromeDriver()
try {
driver.get("https://example.com")
driver.manage().addCookie(Cookie("test1", "cookie1"))
driver.manage().addCookie(Cookie("test2", "cookie2"))
// Get All available cookies
val cookies = driver.manage().cookies
println(cookies)
} finally {
driver.quit()
}
}
Delete Cookie
It deletes the cookie data matching with the provided cookie name.
driver.get("https://www.selenium.dev/selenium/web/blank.html");
driver.manage().addCookie(new Cookie("test1", "cookie1"));
// delete cookie named
driver.manage().deleteCookieNamed("test1"); driver = webdriver.Chrome()
driver.get("http://www.example.com")
driver.add_cookie({"name": "test1", "value": "cookie1"})
driver.add_cookie({"name": "test2", "value": "cookie2"})
# Delete cookie with name 'test1'
driver.delete_cookie("test1") driver.Url = "https://www.selenium.dev/selenium/web/blank.html";
driver.Manage().Cookies.AddCookie(new Cookie("test1", "cookie1"));
// delete cookie named
driver.Manage().Cookies.DeleteCookieNamed("test1");require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome
begin
driver.get 'https://www.example.com'
driver.manage.add_cookie(name: "test1", value: "cookie1")
driver.manage.add_cookie(name: "test2", value: "cookie2")
# delete a cookie with name 'test1'
driver.manage.delete_cookie('test1')
ensure
driver.quit
end
// Delete a cookie with name 'test1'
await driver.manage().deleteCookie('test1');import org.openqa.selenium.Cookie
import org.openqa.selenium.chrome.ChromeDriver
fun main() {
val driver = ChromeDriver()
try {
driver.get("https://example.com")
driver.manage().addCookie(Cookie("test1", "cookie1"))
val cookie1 = Cookie("test2", "cookie2")
driver.manage().addCookie(cookie1)
// delete a cookie with name 'test1'
driver.manage().deleteCookieNamed("test1")
// delete cookie by passing cookie object of current browsing context.
driver.manage().deleteCookie(cookie1)
} finally {
driver.quit()
}
}
Delete All Cookies
It deletes all the cookies of the current browsing context.
driver.get("https://www.selenium.dev/selenium/web/blank.html");
// Add cookies into current browser context
driver.manage().addCookie(new Cookie("test1", "cookie1"));
driver.manage().addCookie(new Cookie("test2", "cookie2"));
// Delete All cookies
driver.manage().deleteAllCookies(); driver = webdriver.Chrome()
driver.get("http://www.example.com")
driver.add_cookie({"name": "test1", "value": "cookie1"})
driver.add_cookie({"name": "test2", "value": "cookie2"})
# Delete all cookies
driver.delete_all_cookies() driver.Url = "https://www.selenium.dev/selenium/web/blank.html";
// Add cookies into current browser context
driver.Manage().Cookies.AddCookie(new Cookie("test1", "cookie1"));
driver.Manage().Cookies.AddCookie(new Cookie("test2", "cookie2"));
// Delete All cookies
driver.Manage().Cookies.DeleteAllCookies();require 'selenium-webdriver'

begin
driver.get 'https://www.example.com'
driver.manage.add_cookie(name: "test1", value: "cookie1")
driver.manage.add_cookie(name: "test2", value: "cookie2")
# deletes all cookies
driver.manage.delete_all_cookies
ensure
driver.quit
end
// Delete all cookies
await driver.manage().deleteAllCookies();import org.openqa.selenium.Cookie
import org.openqa.selenium.chrome.ChromeDriver
fun main() {
val driver = ChromeDriver()
try {
driver.get("https://example.com")
driver.manage().addCookie(Cookie("test1", "cookie1"))
driver.manage().addCookie(Cookie("test2", "cookie2"))
// deletes all cookies
driver.manage().deleteAllCookies()
} finally {
driver.quit()
}
}
Same-Site Cookie Attribute
It allows a user to instruct browsers to control whether cookies are sent along with the request initiated by third party sites. It is introduced to prevent CSRF (Cross-Site Request Forgery) attacks.
Same-Site cookie attribute accepts two parameters as instructions
Strict:
When the sameSite attribute is set as Strict, the cookie will not be sent along with requests initiated by third party websites.
Lax:
When you set a cookie sameSite attribute to Lax, the cookie will be sent along with the GET request initiated by third party website.
Note: As of now this feature is landed in chrome(80+version), Firefox(79+version) and works with Selenium 4 and later versions.
