Double click in Selenium Python - Practice Problems & Coding Challenges

Challenge - 5 Problems

❓ Predict Output

What is the result of this Selenium double click action?

Consider the following Selenium Python code snippet that performs a double click on a button. What will be the value of the button's text after the double click?

Selenium Python

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains

class DummyButton:
    def __init__(self):
        self.text = "Click me"
    def double_click(self):
        self.text = "Double clicked"

button = DummyButton()
actions = ActionChains(None)  # None used as placeholder

# Simulate double click by calling method
button.double_click()

result = button.text
print(result)

A "Click me"

B AttributeError

C "Double clicked"

D TypeError

💡 Hint

Think about what the double_click method does to the button's text.

The double_click method changes the button's text from "Click me" to "Double clicked". Since the method is called, the text updates accordingly.

❓ locator

intermediate

Which locator is best for double clicking a button with text 'Submit'?

You want to perform a double click on a button that has the visible text 'Submit'. Which locator strategy is the best to find this button reliably?

A driver.find_element(By.XPATH, "//button[text()='Submit']")

B driver.find_element(By.ID, "submit")

C driver.find_element(By.CLASS_NAME, "btn")

D driver.find_element(By.CSS_SELECTOR, "button:contains('Submit')")

💡 Hint

Look for the locator that matches the exact button text.

Using XPath with exact text matching ensures you find the button with text 'Submit'. ID or class may not be unique or present. CSS :contains is not supported in Selenium.

❓ assertion

advanced

Which assertion correctly verifies a double click changed the element's text?

After performing a double click on an element, you want to assert that its text changed to 'Clicked Twice'. Which assertion is correct?

A assert element.text == 'Clicked Twice'

B assert element.get_attribute('text') == 'Clicked Twice'

C assert element.value == 'Clicked Twice'

D assert element.text_content == 'Clicked Twice'

💡 Hint

Check how Selenium exposes visible text of elements.

In Selenium Python, the visible text of an element is accessed via the .text property. Other options are invalid or do not return visible text.

🔧 Debug

advanced

Why does this double click code raise an error?

Given the code below, why does it raise a NameError? from selenium import webdriver from selenium.webdriver.common.action_chains import ActionChains button = driver.find_element(By.ID, 'btn') actions = ActionChains(driver) actions.double_click(button) # Missing perform call # What is the cause of the error?

A Because double_click method does not exist in ActionChains

B Because driver is not defined before use

C Because button element is not clickable

D Because actions.double_click(button) does not execute without actions.perform()

💡 Hint

Check if all variables are properly initialized before use.

The code raises a NameError because driver is not defined before calling driver.find_element or ActionChains(driver).

❓ framework

Which test framework setup correctly supports double click tests with Selenium in Python?

You want to write automated tests that include double click actions using Selenium and pytest. Which setup code correctly initializes the WebDriver and performs a double click in a pytest test function?

A

import pytest
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains

@pytest.fixture(scope='module')
def driver():
    driver = webdriver.Chrome()
    yield driver
    driver.quit()

def test_double_click(driver):
    driver.get('http://example.com')
    button = driver.find_element(By.ID, 'btn')
    ActionChains(driver).double_click(button).perform()
    assert button.text == 'Double clicked'

B

import unittest
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains

def test_double_click():
    driver = webdriver.Chrome()
    driver.get('http://example.com')
    button = driver.find_element(By.ID, 'btn')
    ActionChains(driver).double_click(button).perform()
    assert button.text == 'Double clicked'
    driver.quit()

C

import pytest
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains

def test_double_click():
    driver = webdriver.Chrome()
    driver.get('http://example.com')
    button = driver.find_element(By.ID, 'btn')
    ActionChains(driver).double_click(button).perform()
    assert button.text == 'Double clicked'
    driver.quit()

D

import pytest
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains

@pytest.fixture
def driver():
    driver = webdriver.Chrome()
    yield driver
    driver.quit()

def test_double_click(driver):
    driver.get('http://example.com')
    button = driver.find_element(By.ID, 'btn')
    ActionChains(driver).double_click(button).perform()
    assert button.text == 'Double clicked'

💡 Hint

Look for proper pytest fixture usage and driver cleanup.

Option D correctly uses a pytest fixture to initialize and quit the driver, and performs the double click with assertion inside a test function. Option D uses unittest style without a class. Option D lacks fixture and may cause resource leaks. Option D uses driver.close() which closes window but not quits driver.
