What is the significance of Page Factory in Selenium?

Page Factory in Selenium is a pattern and tool for simplifying the initialization of page elements in tests. It allows declaring web elements using annotations (e.g., @FindBy), and then automatically initializes them when creating a page object.

The value of Page Factory:

• Improves code readability and maintainability, as elements are described centrally.
• Enables lazy loading of elements, which increases test performance.
• Reduces boilerplate code for element lookup.

Example in Java:

public class LoginPage {
    @FindBy(id = "username")
    private WebElement usernameInput;

    @FindBy(id = "password")
    private WebElement passwordInput;

    @FindBy(id = "loginBtn")
    private WebElement loginButton;

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

    public void login(String user, String pass) {
        usernameInput.sendKeys(user);
        passwordInput.sendKeys(pass);
        loginButton.click();
    }
}

Thus, Page Factory simplifies working with elements and makes tests more structured.
