@FindBy annotations in Selenium Java - Test Execution Trace

Test Overview

This test uses the @FindBy annotation to locate a login button on a web page and verifies that the button is clickable and has the correct label.

Test Code - JUnit with Selenium

import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;

public class LoginPageTest {
    WebDriver driver;

    public static class LoginPage {
        @FindBy(id = "loginBtn")
        WebElement loginButton;

        public LoginPage(WebDriver driver) {
            PageFactory.initElements(driver, this);
        }

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

        public String getLoginButtonText() {
            return loginButton.getText();
        }
    }

    LoginPage loginPage;

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

    @Test
    public void testLoginButton() {
        assertTrue(loginPage.loginButton.isDisplayed(), "Login button should be visible");
        assertEquals("Log In", loginPage.getLoginButtonText(), "Login button text should be 'Log In'");
        loginPage.clickLogin();
        // Additional assertions can be added here after click
    }

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

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Chrome browser window is open and ready	-	PASS
2	Navigates to https://example.com/login	Login page is loaded in the browser	-	PASS
3	PageFactory initializes elements annotated with @FindBy	loginButton WebElement is located by id 'loginBtn'	loginButton element is found and ready	PASS
4	Checks if loginButton is displayed	Login button is visible on the page	assertTrue(loginButton.isDisplayed()) verifies visibility	PASS
5	Gets text of loginButton and verifies it equals 'Log In'	Login button text is 'Log In'	assertEquals('Log In', loginButton.getText()) verifies label	PASS
6	Clicks the loginButton	Login button is clicked, triggering login action	-	PASS
7	Test ends and browser closes	Browser window is closed	-	PASS

Failure Scenario

Failing Condition: The element with id 'loginBtn' is not found on the page

Execution Trace Quiz - 3 Questions

What does the @FindBy annotation do in this test?

A Starts the browser

B Locates the web element by a specified selector before test actions

C Clicks the button automatically

D Verifies the button text

Key Result

Using @FindBy annotations with PageFactory helps organize element locators clearly and initializes them before test actions, improving code readability and maintainability.
