💡 Hint

Common Mistakes

Using send_keys instead of click to select the checkbox.

Trying to clear a checkbox which is not applicable.

To select or toggle a checkbox in Selenium, you use the click() method on the checkbox element.

Complete the code to check if the checkbox is selected.

Selenium Python

checkbox = driver.find_element(By.ID, "agree")
is_checked = checkbox.[1]()

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

Ais_enabled()

Bis_selected()

💡 Hint

Common Mistakes

Using is_displayed() which checks visibility, not selection.

Using a non-existent method is_checked().

The is_selected() method returns True if the checkbox is checked, otherwise False.

Fix the error in the code to uncheck the checkbox if it is selected.

Selenium Python

checkbox = driver.find_element(By.ID, "notify")
if checkbox.[1]():
    checkbox.click()

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

Bis_displayed

Cis_selected

Dis_checked

💡 Hint

Common Mistakes

Using is_enabled() which checks if element is interactable, not selected.

Using is_displayed() which checks visibility, not selection.

To check if a checkbox is selected, use is_selected(). If it is selected, clicking it will uncheck it.

4fill in blank

hard

Fill both blanks to select the checkbox only if it is not already selected.

Selenium Python

checkbox = driver.find_element(By.ID, "terms")
if not checkbox.[1]():
    checkbox.[2]()

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

Cis_enabled

💡 Hint

Common Mistakes

Using clear() to uncheck which is not valid for checkboxes.

Checking is_enabled() instead of is_selected().

Check if the checkbox is not selected using is_selected(). If not selected, use click() to select it.

5fill in blank

hard

Fill all three blanks to create a function that toggles a checkbox by its ID.

Selenium Python

def toggle_checkbox(driver, checkbox_id):
    checkbox = driver.find_element(By.ID, [1])
    if checkbox.[2]():
        checkbox.[3]()

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

Acheckbox_id

Bis_selected

Cclick

D"terms"

💡 Hint

Common Mistakes

Using a fixed string instead of the variable for the ID.

Using is_enabled() instead of is_selected() for checking.

Not clicking to toggle the checkbox.

The function finds the checkbox by the given ID string (passed as a variable). It checks if the checkbox is selected using is_selected(). If it is selected, it clicks to toggle it off.

Practice

1. What does the is_selected() method do when used on a checkbox element in Selenium?

easy

A. It unchecks the checkbox if it is selected.

B. It clicks the checkbox to select it.

C. It finds the checkbox element on the page.

D. It checks if the checkbox is currently checked (selected).

Solution

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

   This method returns a boolean indicating if the checkbox is checked or not.

2. Step 2: Differentiate from other methods

   Unlike click() which changes state, is_selected() only reads the current state.

3. Final Answer:

   It checks if the checkbox is currently checked (selected). -> Option D

4. Quick Check:

   Check checkbox state = is_selected() [OK]

Hint: Remember: is_selected() reads state, click() changes it [OK]

Common Mistakes:

• Confusing is_selected() with click()
• Thinking is_selected() changes checkbox state
• Using is_selected() to find elements

2. Which of the following is the correct way to click a checkbox using Selenium in Python?

easy

A. checkbox.toggle()

B. checkbox.click()

C. checkbox.check()

D. checkbox.select()

Solution

1. Step 1: Recall Selenium method for clicking

   The standard method to simulate a mouse click on an element is click().

2. Step 2: Verify other options

   Methods like select(), check(), or toggle() do not exist in Selenium WebDriver API.

3. Final Answer:

   checkbox.click() -> Option B

4. Quick Check:

   Click checkbox = click() method [OK]

Hint: Use click() to change checkbox state, no other method works [OK]

Common Mistakes:

• Using non-existent methods like select() or check()
• Trying to assign True/False directly to checkbox
• Confusing click() with is_selected()

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

checkbox = driver.find_element(By.ID, 'subscribe')
checkbox.click()
print(checkbox.is_selected())

medium

A. True

B. False

C. None

D. Throws an exception

Solution

1. Step 1: Understand the code actions

   The code finds a checkbox by ID 'subscribe', clicks it to select, then prints if it is selected.

2. Step 2: Predict the checkbox state after click()

   Clicking a checkbox toggles it to selected if it was not selected before, so is_selected() returns True.

3. Final Answer:

   True -> Option A

4. Quick Check:

   Click then check selected = True [OK]

Hint: Click toggles checkbox, is_selected() shows True if checked [OK]

Common Mistakes:

• Assuming is_selected() returns False after click
• Thinking print outputs None
• Expecting an exception without errors in code

4. You wrote this code to select a checkbox:

checkbox = driver.find_element(By.NAME, 'agree')
if not checkbox.is_selected():
    checkbox.click()

But the checkbox is never selected after running. What is the likely problem?

medium

A. The locator By.NAME with 'agree' is incorrect or does not find the checkbox.

B. The click() method does not work on checkboxes.

C. You must use checkbox.select() instead of click().

D. The is_selected() method changes the checkbox state.

Solution

1. Step 1: Analyze the locator usage

   If the checkbox is never selected, the element might not be found correctly by By.NAME, 'agree'.

2. Step 2: Check method correctness

   click() works on checkboxes, and is_selected() only reads state, so these are not the problem.

3. Final Answer:

   The locator By.NAME with 'agree' is incorrect or does not find the checkbox. -> Option A

4. Quick Check:

   Wrong locator = no click effect [OK]

Hint: Verify locators first if click has no effect [OK]

Common Mistakes:

• Assuming click() doesn't work on checkboxes
• Using non-existent methods like select()
• Thinking is_selected() changes state

5. You want to write a Selenium test that ensures a checkbox with ID 'terms' is checked only if it is not already checked. Which code snippet correctly does this?

hard

A. checkbox = driver.find_element(By.ID, 'terms')
if checkbox.is_selected():
checkbox.click()

B. checkbox = driver.find_element(By.ID, 'terms')
checkbox.click()
assert checkbox.is_selected()

C. checkbox = driver.find_element(By.ID, 'terms')
if not checkbox.is_selected():
checkbox.click()

D. checkbox = driver.find_element(By.ID, 'terms')
checkbox.select()

Solution

1. Step 1: Understand the requirement

   The checkbox should be checked only if it is not already checked to avoid toggling it off.

2. Step 2: Analyze each option

   checkbox = driver.find_element(By.ID, 'terms') if not checkbox.is_selected(): checkbox.click() checks state and clicks only if unchecked, which is correct. checkbox = driver.find_element(By.ID, 'terms') checkbox.click() assert checkbox.is_selected() always clicks, possibly unchecking. checkbox = driver.find_element(By.ID, 'terms') if checkbox.is_selected(): checkbox.click() clicks if already checked, unchecking it. checkbox = driver.find_element(By.ID, 'terms') checkbox.select() uses a non-existent method.

3. Final Answer:

   checkbox = driver.find_element(By.ID, 'terms') if not checkbox.is_selected(): checkbox.click() -> Option C

4. Quick Check:

   Check state before click to avoid toggling off [OK]

Hint: Click only if not selected to ensure checkbox is checked [OK]

Common Mistakes:

• Clicking checkbox without checking state first
• Using non-existent methods like select()
• Clicking when checkbox is already selected
