How to handle cookies in selenium
Selenium WebDriver provides full support for working with cookies. You can add, retrieve, delete, and manage cookies during your automation session.
Real-World Usage Examples
- Session Handling:
Store session cookies to bypass login on subsequent runs.
- Cookie-based Authentication:
Inject a cookie after login, or set pre-authenticated cookies for test setup.
- Testing Cookie-related Features:
Add/modify cookies to test how your app behaves.
Sample Program:
filename.js
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.Cookie;
import java.util.Set;
public class CookiesDemo {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
WebDriver driver = new ChromeDriver();
try {
driver.get("https://example.com");
// Add a cookie
Cookie cookie = new Cookie("testCookie", "Selenium123");
driver.manage().addCookie(cookie);
// Get all cookies
Set<Cookie> allCookies = driver.manage().getCookies();
System.out.println("All Cookies:");
for (Cookie c : allCookies) {
System.out.println(c.getName() + " = " + c.getValue());
}
// Get a specific cookie
Cookie myCookie = driver.manage().getCookieNamed("testCookie");
System.out.println("testCookie value: " + myCookie.getValue());
// Delete a cookie
driver.manage().deleteCookieNamed("testCookie");
// Delete all cookies
driver.manage().deleteAllCookies();
} finally {
driver.quit();
}
}
}Tips
- Cookies are domain-specific: Add them after navigating to the correct domain!
- Can set additional properties: domain, path, expiry, secure, etc.
filename.js
Cookie customCookie = new Cookie.Builder("name", "value")
.domain("example.com")
.path("/")
.isHttpOnly(true)
.build();
