Cookie management in Selenium Java - Test Execution Trace

Test Overview

This test opens a website, adds a cookie, verifies the cookie is set, deletes the cookie, and confirms it is removed.

Test Code - JUnit 5 with Selenium WebDriver

Selenium Java

import org.openqa.selenium.Cookie;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.junit.jupiter.api.*;
import static org.junit.jupiter.api.Assertions.*;

public class CookieManagementTest {
    private WebDriver driver;

    @BeforeEach
    public void setUp() {
        driver = new ChromeDriver();
    }

    @AfterEach
    public void tearDown() {
        driver.quit();
    }

    @Test
    public void testAddAndDeleteCookie() {
        driver.get("https://example.com");

        Cookie cookie = new Cookie.Builder("testCookie", "testValue")
                .domain("example.com")
                .path("/")
                .build();

        driver.manage().addCookie(cookie);

        Cookie retrievedCookie = driver.manage().getCookieNamed("testCookie");
        assertNotNull(retrievedCookie, "Cookie should be present after adding");
        assertEquals("testValue", retrievedCookie.getValue(), "Cookie value should match");

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

        Cookie deletedCookie = driver.manage().getCookieNamed("testCookie");
        assertNull(deletedCookie, "Cookie should be deleted and not present");
    }
}

Execution Trace - 8 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Browser window is open but no page loaded	-	PASS
2	Navigates to https://example.com	Example.com homepage is loaded in browser	-	PASS
3	Creates a cookie named 'testCookie' with value 'testValue' for domain example.com	Cookie object created in test code	-	PASS
4	Adds the cookie to the browser session	Browser now has cookie 'testCookie' set	-	PASS
5	Retrieves cookie named 'testCookie' from browser	Cookie 'testCookie' is found in browser cookies	Assert cookie is not null and value equals 'testValue'	PASS
6	Deletes cookie named 'testCookie' from browser	Cookie 'testCookie' removed from browser cookies	-	PASS
7	Attempts to retrieve cookie named 'testCookie' after deletion	No cookie named 'testCookie' found	Assert cookie is null (deleted)	PASS
8	Test ends and browser closes	Browser window closed	-	PASS

Failure Scenario

Failing Condition: Cookie 'testCookie' is not found after adding or still present after deletion

Execution Trace Quiz - 3 Questions

What does the test verify after adding the cookie?

A The cookie exists and its value matches 'testValue'

B The cookie is deleted immediately

C The browser navigates to a new page

D The cookie domain is changed

Key Result

Always verify cookies after adding or deleting them by retrieving them explicitly to confirm the browser state matches expectations.
