Purpose of Page Object Model

What is the main purpose of using the Page Object Model (POM) in software testing?

A To automatically generate test data for input fields

B To speed up test execution by running tests in parallel

C To separate test code from page-specific code to improve maintainability

D To replace manual testing with exploratory testing

💡 Hint

Think about how POM helps when the web page changes.

The Page Object Model helps keep the code organized by separating the page structure and actions from the test logic. This makes tests easier to maintain when the UI changes.

Output of POM method call

Given the following simplified Page Object Model class and test code, what will be printed?

Testing Fundamentals

class LoginPage:
    def __init__(self):
        self.page_title = "Login Page"
    def get_title(self):
        return self.page_title

page = LoginPage()
print(page.get_title())

A Login Page

B page_title

C None

D Error: get_title is not defined

💡 Hint

Look at what get_title() returns.

The method get_title() returns the string stored in the page_title attribute, which is "Login Page".

❓ locator

Best locator strategy in POM

Which locator strategy is considered best practice for identifying a button in a Page Object Model class for stable and maintainable tests?

A Using class name that is shared by many buttons like .btn

B Using XPath with absolute path like /html/body/div[2]/button[1]

C Using text content matching like button[text()='Submit']

D Using CSS selector with a unique ID attribute like #submitBtn

💡 Hint

Unique and stable attributes are best for locators.

Using a unique ID attribute with a CSS selector is the most stable and maintainable locator strategy. Absolute XPath is fragile, text matching can break if text changes, and class names may not be unique.

❓ assertion

advanced

Correct assertion for page title

In a test using POM, which assertion correctly verifies that the page title is exactly 'Dashboard'?

Testing Fundamentals

page = DashboardPage()
actual_title = page.get_title()

A assert actual_title == 'Dashboard'

B assert actual_title > 'Dashboard'

C assert actual_title != 'Dashboard'

D assert 'Dashboard' in actual_title

💡 Hint

Check for exact match, not partial or inequality.

To verify the page title exactly matches 'Dashboard', use equality assertion. Option A checks only if 'Dashboard' is part of the title, which is less strict.

❓ framework

expert

POM integration with test framework

In a test automation framework using POM, which practice best supports test scalability and reusability?

A Instantiate page objects inside each test method separately

B Create a base test class that initializes page objects once per test class

C Write all test steps directly inside the test methods without page objects

D Use global variables for page objects shared across all tests

💡 Hint

Think about avoiding repeated code and easy maintenance.

Creating a base test class that initializes page objects once per test class promotes reusability and reduces duplication. Instantiating inside each test method repeats code, and global variables can cause test interference.
