Radio button interactions in Selenium Python - Practice Problems & Coding Challenges

Challenge - 5 Problems

❓ Predict Output

What is the output of this Selenium Python code snippet?

Given a webpage with radio buttons named 'color' and the following Selenium code, what will be printed?

Selenium Python

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

# Assume driver is already initialized and page loaded
radio_buttons = driver.find_elements(By.NAME, 'color')
for rb in radio_buttons:
    if rb.is_selected():
        print(rb.get_attribute('value'))
        break
else:
    print('No selection')

A Prints 'No selection' even if a radio button is selected

B Prints all values of all radio buttons regardless of selection

C Prints the value attribute of the first selected radio button

D Raises NoSuchElementException if no radio button is selected

💡 Hint

Check how the loop and break statement work with is_selected()

The code loops through all radio buttons named 'color'. It prints the value of the first one that is selected and then stops. If none are selected, it prints 'No selection'.

❓ assertion

intermediate

Which assertion correctly verifies a radio button is selected?

You want to assert that the radio button with id 'option1' is selected. Which assertion is correct in Selenium Python?

Selenium Python

radio_button = driver.find_element(By.ID, 'option1')

A assert radio_button.is_selected() == True

B assert radio_button.get_attribute('checked') == 'false'

C assert radio_button.is_displayed()

D assert radio_button.get_attribute('value') == 'selected'

💡 Hint

Use the method that checks selection state directly.

The is_selected() method returns True if the radio button is selected. Checking 'checked' attribute or 'value' does not reliably confirm selection.

❓ locator

advanced

Which locator is best to select a radio button with label text 'Male'?

You want to select the radio button associated with the label text 'Male'. Which locator is the best practice in Selenium Python?

A driver.find_element(By.XPATH, "//label[text()='Male']/preceding-sibling::input[@type='radio']")

B driver.find_element(By.ID, 'maleRadio')

C driver.find_element(By.CSS_SELECTOR, "input[type='radio'][value='Male']")

D driver.find_element(By.NAME, 'gender')

💡 Hint

Consider the relationship between label and input elements.

Option A uses XPath to find the input radio button that is a sibling before the label with text 'Male', which directly associates the label text with the radio button. Other options may not uniquely identify the correct radio button.

🔧 Debug

advanced

Why does this Selenium Python code fail to select a radio button?

Code snippet: radio_button = driver.find_element(By.ID, 'option2') radio_button.click() But the radio button remains unselected after running. What is the most likely reason?

A The locator ID 'option2' is incorrect and finds no element

B The radio button is disabled or not interactable

C The click() method does not work on radio buttons

D The page has not finished loading before click()

💡 Hint

Check if the element can be clicked or is enabled.

If the radio button is disabled or hidden, click() will not select it. The locator is assumed correct here. click() works on radio buttons. Page loading issues usually cause exceptions.

❓ framework

expert

In a test framework, how to best verify only one radio button is selected among a group?

You have a group of radio buttons named 'payment'. Which approach best verifies exactly one is selected using Selenium Python?

A assert any(rb.is_selected() for rb in driver.find_elements(By.NAME, 'payment'))

B assert driver.find_element(By.NAME, 'payment').is_selected()

C assert driver.find_elements(By.NAME, 'payment')[0].is_selected()

D selected = [rb for rb in driver.find_elements(By.NAME, 'payment') if rb.is_selected()]; assert len(selected) == 1

💡 Hint

Count how many radio buttons are selected, not just check one.

Option D collects all selected radio buttons and asserts exactly one is selected. Other options only check one element or if any is selected, not ensuring exactly one.
