Getting element attributes in Selenium Python - Practice Problems & Coding Challenges

Challenge - 5 Problems

What is the output of this Selenium Python code snippet?

Consider the following Selenium code that fetches an attribute from a web element. What will be printed?

Selenium Python

from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.webdriver import WebDriver

class DummyDriver:
    def find_element(self, by, value):
        class DummyElement:
            def get_attribute(self, attr):
                if attr == 'href':
                    return 'https://example.com'
                return None
        return DummyElement()

driver = DummyDriver()
element = driver.find_element(By.ID, 'link')
print(element.get_attribute('href'))

A https://example.com

B None

C AttributeError

D '' (empty string)

💡 Hint

The get_attribute method returns the value of the attribute if it exists, otherwise None.

The DummyElement's get_attribute method returns 'https://example.com' when asked for 'href'. So the print statement outputs that string.

❓ assertion

intermediate

Which assertion correctly verifies the 'title' attribute of a web element?

You want to check that a web element's 'title' attribute equals 'Submit Button'. Which assertion is correct?

Selenium Python

title_value = element.get_attribute('title')

A assert title_value == 'Submit Button'

B assert element.get_attribute('title') is 'Submit Button'

C assert title_value.equals('Submit Button')

D assert title_value = 'Submit Button'

💡 Hint

Use '==' to compare strings in Python, not 'is' or '='.

Option A uses the correct equality operator '==' to compare strings. Option A uses 'is' which checks identity, not equality. Option A uses a method that doesn't exist for strings. Option A uses assignment '=' inside assert which is invalid syntax.

❓ locator

advanced

Which locator strategy is best to get an element by its 'data-test-id' attribute?

You want to find an element with attribute data-test-id='login-btn'. Which locator is correct and follows best practices?

A driver.find_element(By.XPATH, '//*[@data-test-id="login-btn"]')

B driver.find_element(By.ID, 'login-btn')

C driver.find_element(By.CSS_SELECTOR, '[data-test-id="login-btn"]')

D driver.find_element(By.CLASS_NAME, 'login-btn')

💡 Hint

Use CSS selectors for custom attributes with quotes.

Option C correctly uses CSS selector with attribute selector and quotes. Option C looks for an ID which is different. Option C now correctly includes quotes around the attribute value to avoid XPath error. Option C looks for a class name which is unrelated.

🔧 Debug

advanced

What error does this Selenium code raise?

What error will this code raise when trying to get an attribute?

Selenium Python

element = driver.find_element(By.ID, 'submit')
value = element.get_attribute()

A None

B AttributeError: 'WebElement' object has no attribute 'get_attribute'

C NoSuchElementException

D TypeError: get_attribute() missing 1 required positional argument: 'name'

💡 Hint

Check the method signature for get_attribute.

get_attribute requires one argument: the attribute name. Calling it without arguments causes a TypeError.

❓ framework

expert

In a pytest Selenium test, which fixture usage correctly retrieves an element's attribute for assertion?

Given a pytest fixture 'driver' that provides a Selenium WebDriver instance, which test function correctly asserts the 'alt' attribute of an image element?

Selenium Python

import pytest
from selenium.webdriver.common.by import By

@pytest.fixture
def driver():
    # returns a WebDriver instance
    pass

def test_image_alt_attribute(driver):
    element = driver.find_element(By.TAG_NAME, 'img')
    alt_text = element.get_attribute('alt')
    # assertion here

A assert alt_text = 'Company Logo'

B assert alt_text == 'Company Logo'

C assert alt_text.equals('Company Logo')

D assert element.get_attribute('alt') is 'Company Logo'

💡 Hint

Use '==' for string comparison in assertions.

Option B correctly asserts string equality. Option B uses 'is' which checks identity, not equality. Option B uses a non-existent method. Option B uses assignment inside assert which is invalid.
