Page class design in Selenium Java - Test Execution Trace

Test Overview

This test verifies that the Page class correctly locates and interacts with the login button on a web page. It checks that clicking the button triggers the expected behavior.

Test Code - JUnit 5 with Selenium WebDriver

    public WebElement getLoginButton() {

    }

    @Test
    public void testClickLoginButton() {
        loginPage.clickLogin();
        String currentUrl = driver.getCurrentUrl();
        assertTrue(currentUrl.contains("dashboard"), "URL should contain 'dashboard' after login click");
    }

    @AfterEach
    public void tearDown() {

Execution Trace - 8 Steps

Step	Action	System State	Assertion	Result
1	Test starts	JUnit test runner initialized	-	PASS
2	Browser opens ChromeDriver	Chrome browser window opens	-	PASS
3	Navigates to https://example.com/login	Login page is loaded in browser	Page URL is https://example.com/login	PASS
4	LoginPage object is created with driver	Page class ready to interact with elements	-	PASS
5	Finds login button by id 'login-btn'	Login button element is located on page	Element is present and visible	PASS
6	Clicks login button	Browser processes click event	-	PASS
7	Checks current URL contains 'dashboard'	Browser URL updated after click	assertTrue(currentUrl.contains("dashboard"))	PASS
8	Test ends and browser closes	Browser window closed, resources freed	-	PASS

Failure Scenario

Failing Condition: Login button with id 'login-btn' is not found on the page

Execution Trace Quiz - 3 Questions

What does the test verify after clicking the login button?

A The URL contains 'dashboard'

B The login button disappears

C The page title changes to 'Login'

D An alert popup appears

Key Result

Designing a Page class with clear element locators and interaction methods helps keep tests clean and easy to maintain.
