Purpose of Page Object Model (POM) in test code organization

Why do testers use the Page Object Model (POM) to organize their Selenium test code?

A To separate page structure and test logic, making tests easier to maintain and read

B To avoid using locators and directly interact with browser elements

C To write tests without any reusable code or functions

D To combine all test steps and locators in one large file for faster execution

💡 Hint

Think about how organizing code helps when the website changes.

POM separates the page details (locators and actions) from test scripts. This makes tests easier to update and understand.

Output of test using POM method call

Given the following simplified POM class and test code, what will be printed?

Selenium Python

class LoginPage:
    def __init__(self):
        self.username = "user123"
    def get_username(self):
        return self.username

page = LoginPage()
print(page.get_username())

A user123

B self.username

C None

D Error: get_username() missing 1 required positional argument

💡 Hint

Look at what get_username() returns.

The method get_username returns the username string stored in the object.

❓ locator

advanced

Best locator practice in POM for a login button

Which locator is best to use in a POM class for a login button to ensure maintainability?

A By.CLASS_NAME, "btn-primary login"

B By.XPATH, "//button[text()='Login']"

C By.CSS_SELECTOR, "button:nth-child(3)"

D By.ID, "login-btn"

💡 Hint

Think about which locator is least likely to break if the page layout changes.

ID locators are unique and stable, making them the best choice for maintainability.

❓ assertion

advanced

Correct assertion for verifying login success message

Which assertion correctly checks that the login success message equals "Welcome, user!" in a test using POM?

Selenium Python

message = page.get_success_message()

A assert message is None

B assert message != "Welcome, user!"

C assert message == "Welcome, user!"

D assert message.contains("Welcome")

💡 Hint

Check for exact equality of the message string.

The assertion should confirm the message exactly matches the expected text.

Advantage of using POM with pytest fixtures

What is a key advantage of combining the Page Object Model with pytest fixtures in Selenium tests?

A It forces all tests to run sequentially without parallelism

B It allows reusing page objects across multiple tests with clean setup and teardown

C It removes the need for locators in page objects

D It automatically generates test reports without any code

💡 Hint

Think about how fixtures help manage test setup.

pytest fixtures provide a way to create and clean up page objects once per test or session, improving code reuse and clarity.
