Action methods per page in Selenium Java - Test Execution Trace

Test Overview

This test verifies that the login page's action methods work correctly by entering valid credentials and checking successful login.

Test Code - JUnit + Selenium

    private By usernameField = By.id("username");

    private By loginButton = By.id("loginBtn");

    public LoginPage(WebDriver driver) {
        this.driver = driver;
    }

    public void enterUsername(String username) {
        driver.findElement(usernameField).sendKeys(username);
    }

    public void enterPassword(String password) {
        driver.findElement(passwordField).sendKeys(password);
    }

    public void clickLogin() {
        driver.findElement(loginButton).click();
    }
}

public class LoginTest {
    private WebDriver driver;
    private LoginPage loginPage;

    @BeforeEach
    public void setUp() {
        driver = new ChromeDriver();
        driver.get("https://example.com/login");
        loginPage = new LoginPage(driver);
    }

    @Test
    public void testValidLogin() {
        loginPage.enterUsername("testuser");
        loginPage.enterPassword("password123");
        loginPage.clickLogin();
        boolean loggedIn = driver.findElement(By.id("welcomeMessage")).isDisplayed();
        assertTrue(loggedIn, "User should be logged in and welcome message displayed");
    }

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

Execution Trace - 9 Steps

Step	Action	System State	Assertion	Result
1	Test starts	JUnit test runner initialized	-	PASS
2	Browser opens ChromeDriver	Chrome browser window opened	-	PASS
3	Navigates to https://example.com/login	Login page loaded with username, password fields and login button	Page URL is correct	PASS
4	Finds username field and enters 'testuser'	Username input filled with 'testuser'	Username field contains 'testuser'	PASS
5	Finds password field and enters 'password123'	Password input filled with 'password123'	Password field contains 'password123'	PASS
6	Finds and clicks login button	Login form submitted, page navigates	-	PASS
7	Finds welcome message element by id 'welcomeMessage'	Welcome message displayed on page	Welcome message is displayed	PASS
8	Assertion checks user is logged in by verifying welcome message visibility	Test verifies login success	assertTrue(loggedIn) passes	PASS
9	Browser closes and test ends	Chrome browser closed	-	PASS

Failure Scenario

Failing Condition: Welcome message element not found after login attempt

Execution Trace Quiz - 3 Questions

What action does the test perform after opening the login page?

A Enter username and password using page action methods

B Directly click the login button without entering credentials

C Close the browser immediately

D Navigate to a different URL

Key Result

Using action methods in page classes helps keep test code clean and reusable by separating page interactions from test logic.
