9. What is the role of a test script in POM?
   a) It stores UI elements

10. Which of the following is a feature of Page Object Model?
    a) Dependency injection
    b) Separation of test logic and UI logic
    c) Integration with Jenkins
    d) Handling data-driven testing

Implementing POM in Selenium

11. In Selenium, how do you define a page object class?
    a) By extending the WebDriver class
    b) By creating a class with methods representing actions and elements
    c) By using a separate method for each test case
    d) By using @Test annotation
12. Which annotation is commonly used to locate elements in POM?
    a) @Test
    b) @FindBy
    c) @Before
    d) @After
13. In POM, how would you interact with a text field on a page?
    a) Use a method from the page object class
    b) Write the code in the test script directly
    c) Use WebDriver’s findElement() method
    d) Use @Test annotations
14. How do you manage synchronization in POM?
    a) Use explicit waits inside the page object methods
    b) Handle synchronization in the test script only
    c) Use implicit waits globally
    d) No synchronization is required in POM
15. Which of the following is correct for the Page Object in Selenium?
    a) It should store the WebDriver instance
    b) It should directly control the test flow
    c) It should only contain the locators
    d) It should be used to handle alerts
16. What is the purpose of the PageFactory class in POM?
    a) To load test data
    b) To initialize page objects
    c) To execute tests
    d) To store page elements
17. What is the purpose of using @FindBy annotation in POM?
    a) To specify the browser type
    b) To locate and define web elements
    c) To store test data
    d) To configure the test environment
18. In POM, how can you define an action method for clicking a button?
    a) Inside the test script directly
    b) In the page object class using WebDriver actions
    c) Using @Test annotation
    d) Using PageFactory class
19. What is the advantage of separating the test script from the page object?
    a) Easier debugging
    b) Faster execution
    c) Better test reporting
    d) Improved test maintainability
20. How are page objects and test scripts linked in POM?
    a) The test script references the page objects for actions and verifications
    b) Page objects call test scripts for execution
    c) Both are independently executed
    d) Test scripts contain page object class definitions

Advantages of POM

21. Which of the following is a major advantage of using POM?
    a) It helps in code duplication
    b) It allows for better separation of concerns
    c) It increases the size of the test code
    d) It reduces the modularity of the tests
22. How does POM help in improving test maintainability?
    a) By having centralized UI element locators
    b) By merging test cases and page object methods
    c) By reducing the number of test scripts
    d) By executing tests in parallel
23. What makes POM a scalable solution?
    a) The ability to add multiple test cases to a single page object

    c) Storing locators in the test script
    d) Using an external test management tool
24. What is the benefit of using POM for large projects?
