Output of a simple Page class method

Given the following Page class method, what will be the output when calling get_title() if the page title is "Welcome Page"?

Selenium Python

class HomePage:
    def __init__(self, driver):
        self.driver = driver
    def get_title(self):
        return self.driver.title

# Assume driver.title returns "Welcome Page"

A None

B "home page"

C "Welcome Page"

D Raises AttributeError

💡 Hint

Think about what the driver.title property returns.

The get_title method returns the title attribute of the driver, which is "Welcome Page".

❓ assertion

Correct assertion for verifying page URL

Which assertion correctly verifies that the current page URL contains the substring "dashboard" in a Page class test method?

Selenium Python

def test_dashboard_page(self):
    current_url = self.driver.current_url
    # Assertion goes here

A assert "dashboard" in current_url

B assert current_url == "dashboard"

C assert current_url.contains("dashboard")

D assert current_url.index("dashboard")

💡 Hint

Check Python syntax for substring containment.

Option A uses the correct Python syntax to check if "dashboard" is part of the current URL string.

❓ locator

Best locator strategy for a login button

Which locator is the best practice to find a login button with id="loginBtn" in a Page class?

A self.driver.find_element(By.XPATH, "//button[@id='loginBtn']")

B self.driver.find_element(By.ID, "loginBtn")

C self.driver.find_element(By.CSS_SELECTOR, "button#loginBtn")

D self.driver.find_element(By.CLASS_NAME, "loginBtn")

💡 Hint

Using ID is usually the fastest and most reliable locator.

Locating by ID is the most efficient and reliable method when the element has a unique ID.

🔧 Debug

Identify the error in this Page class method

What error will occur when running this method in a Page class?

Selenium Python

def click_submit(self):
    submit_button = self.driver.find_element(By.ID, "submitBtn")
    submit_button.click()

A AttributeError because 'driver' is None

B NoSuchElementException because element not found

C TypeError because click() is called incorrectly

D SyntaxError due to missing comma in find_element arguments

💡 Hint

Check the syntax of the find_element method call.

The find_element method requires two arguments separated by a comma. Missing comma causes SyntaxError.

❓ framework

expert

Page class design for test maintainability

Which design choice best improves maintainability of Page classes in a Selenium Python test framework?

A Store all locators as class-level constants and use methods to interact with elements

B Hardcode XPath strings inside each test method for flexibility

C Use global variables for locators and access them in Page classes

D Write all Selenium commands directly in test methods without Page classes

💡 Hint

Think about how to keep locators organized and reusable.

Storing locators as class-level constants and encapsulating interactions in methods keeps code clean and easy to update.
