1fill in blank

easy

Complete the code to perform a double click on the element.

Selenium Python

from selenium import webdriver
from selenium.webdriver import ActionChains

browser = webdriver.Chrome()
element = browser.find_element('id', 'button')
actions = ActionChains(browser)
actions.[1](element).perform()

💡 Hint

Common Mistakes

Using 'click' instead of 'double_click' will perform a single click.

Using 'context_click' performs a right-click, not a double click.

The double_click method performs a double click on the given element.

Complete the code to locate the element by CSS selector before double clicking.

Selenium Python

from selenium.webdriver.common.by import By

element = browser.find_element(By.[1], '.btn-double')

💡 Hint

Common Mistakes

Using 'ID' when the selector is a class.

Using 'CLASS_NAME' when the selector is a CSS selector string.

To find an element by CSS selector, use By.CSS_SELECTOR.

💡 Hint

Common Mistakes

Calling double_click without parentheses causes a syntax error.

Passing the element without parentheses is invalid syntax.

The double_click method requires the target element as an argument inside parentheses.

Fill both blanks to create an ActionChains object and perform a double click on the element.

Selenium Python

actions = [1](browser)
actions.[2](element).perform()

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'click' instead of 'double_click' for the action.

Using 'webdriver' instead of 'ActionChains' to create the object.

Create an ActionChains object and use double_click to double click the element.

5fill in blank

Fill all three blanks to import ActionChains, create it, and double click the element.

Selenium Python

from selenium.webdriver import [1]
actions = [2](browser)
actions.[3](element).perform()

Common Mistakes

Using 'click' instead of 'double_click' for the action.

Forgetting to import ActionChains.

Import ActionChains, create an instance, and call double_click on the element.

Practice

1. What does the double_click() method in Selenium's ActionChains do?

easy

A. Scrolls the page down twice

B. Clicks and holds the mouse button on an element

C. Right-clicks on a web element

D. Simulates two quick clicks on a web element

Solution

1. Step 1: Understand the purpose of double_click()

   This method is designed to simulate two quick mouse clicks on the same element, mimicking a user's double click action.

2. Step 2: Compare with other mouse actions

   Other actions like click and hold, right-click, or scrolling are different methods in Selenium and do not represent double clicking.

3. Final Answer:

   Simulates two quick clicks on a web element -> Option D

4. Quick Check:

   double_click() = two quick clicks [OK]

Hint: Double click means two fast clicks on the same spot [OK]

Common Mistakes:

• Confusing double click with right click
• Using click_and_hold instead of double_click
• Thinking double_click scrolls the page
• Assuming double_click requires multiple perform() calls

2. Which of the following is the correct syntax to perform a double click on an element stored in variable button using Selenium in Python?

easy

A. ActionChains(driver).double_click(button).perform()

B. ActionChains(driver).click(button).double_click().perform()

C. driver.double_click(button).perform()

D. ActionChains.double_click(button).perform()

Solution

1. Step 1: Identify the correct use of ActionChains

   ActionChains is instantiated with the driver, then the double_click method is called with the element, followed by perform() to execute.

2. Step 2: Check syntax correctness

   ActionChains(driver).double_click(button).perform() correctly chains these calls. Options B, C, and D misuse method calls or omit driver instantiation.

3. Final Answer:

   ActionChains(driver).double_click(button).perform() -> Option A

4. Quick Check:

   Correct chaining = ActionChains(driver).double_click(button).perform() [OK]

Hint: Always instantiate ActionChains with driver before actions [OK]

Common Mistakes:

• Calling double_click without ActionChains instance
• Trying to call double_click directly on driver
• Missing perform() at the end
• Incorrect method chaining order

3. What will be the output of the following Selenium Python code snippet?

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

button = driver.find_element(By.ID, "btn")
actions = ActionChains(driver)
actions.double_click(button).perform()
print("Double click performed")

medium

A. Double click performed

B. SyntaxError

C. No output, code hangs

D. ElementNotInteractableException

Solution

1. Step 1: Analyze the code flow

   The code finds a button element, creates an ActionChains object, performs a double click on the button, then prints a message.

2. Step 2: Check for errors or exceptions

   Assuming the element is interactable and driver is valid, the double click will succeed and print the message.

3. Final Answer:

   Double click performed -> Option A

4. Quick Check:

   Successful double click prints message [OK]

Hint: If no errors, print statements run normally [OK]

Common Mistakes:

• Assuming double_click returns a value to print
• Ignoring element visibility or interactability
• Confusing syntax errors with runtime exceptions
• Missing import statements causing errors

4. You wrote this code to double click an element:

actions = ActionChains(driver)
actions.double_click().perform()

But it throws an error. What is the likely cause?

medium

A. driver is not initialized

B. ActionChains must be imported from selenium.webdriver.common.keys

C. Missing the target element in double_click() method

D. perform() should be called before double_click()

Solution

1. Step 1: Check method usage

   The double_click() method requires the element to double click on as an argument. Omitting it causes an error.

2. Step 2: Validate other options

   ActionChains is imported from selenium.webdriver.common.action_chains, not common.keys. perform() must be last. Driver initialization error would cause different error.

3. Final Answer:

   Missing the target element in double_click() method -> Option C

4. Quick Check:

   double_click() needs element argument [OK]

Hint: Always pass element to double_click() [OK]

Common Mistakes:

• Calling double_click() without element
• Wrong import for ActionChains
• Calling perform() too early
• Ignoring driver initialization errors

5. You want to test a web app feature that opens a hidden menu on double clicking a div with id "menu". Which Selenium Python code snippet correctly performs this test?

hard

A. menu = driver.find_element(By.ID, "menu")
menu.double_click()
assert driver.find_element(By.ID, "hidden-menu").is_displayed()

B. menu = driver.find_element(By.ID, "menu")
ActionChains(driver).double_click(menu).perform()
assert driver.find_element(By.ID, "hidden-menu").is_displayed()

C. ActionChains(driver).double_click(By.ID, "menu").perform()
assert driver.find_element(By.ID, "hidden-menu").is_displayed()

D. menu = driver.find_element(By.ID, "menu")
ActionChains.double_click(menu).perform()
assert driver.find_element(By.ID, "hidden-menu").is_displayed()

Solution

1. Step 1: Locate the element correctly

   Use driver.find_element with By.ID to get the div with id "menu".

2. Step 2: Use ActionChains instance to double click

   Create ActionChains(driver), call double_click(menu), then perform() to execute the action.

3. Step 3: Assert the hidden menu is displayed

   Check if the element with id "hidden-menu" is visible after the double click.

4. Final Answer:

   Correctly locate, double click, and assert visibility -> Option B

5. Quick Check:

   Find element + double_click + assert visible = menu = driver.find_element(By.ID, "menu") ActionChains(driver).double_click(menu).perform() assert driver.find_element(By.ID, "hidden-menu").is_displayed() [OK]

Hint: Find element first, then double click with ActionChains [OK]

Common Mistakes:

• Calling double_click directly on element
• Passing locator instead of element to double_click
• Using ActionChains class method without instance
• Skipping assertion after action
