Handling CAPTCHAs (strategies) in Selenium Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to pause the test and let the tester solve the CAPTCHA manually.

Selenium Python

input('Please solve the CAPTCHA and press Enter to continue...')  # [1]

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

Ainput

Bwait

Csleep

Dpause

Attempts:

3 left

💡 Hint

Common Mistakes

Using sleep() only waits a fixed time and does not wait for user action.

Using pause or wait are not valid Python functions.

Using the input() function pauses the test execution and waits for the tester to press Enter after solving the CAPTCHA manually.

medium

Complete the code to detect if a CAPTCHA element is present on the page.

Selenium Python

captcha_present = len(driver.find_elements(By.ID, '[1]')) > 0

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

Acaptcha

Bcaptcha_element

Ccaptcha_box

Dcaptcha_image

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect or uncommon element IDs.

Using find_element instead of find_elements which throws error if not found.

The CAPTCHA element usually has the ID 'captcha'. Checking if elements with this ID exist helps detect CAPTCHA presence.

3fill in blank

hard

Fix the error in the code that tries to click the CAPTCHA checkbox but fails if not found.

Selenium Python

try:
    driver.find_element(By.ID, '[1]').click()
except NoSuchElementException:
    print('CAPTCHA checkbox not found')

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

Acaptcha

Bcaptcha_check

Ccaptcha_box

Dcaptcha_checkbox

Attempts:

3 left

💡 Hint

Common Mistakes

Using a generic 'captcha' ID that does not match the checkbox.

Not handling exceptions causing test to crash.

The correct ID for the CAPTCHA checkbox is 'captcha_checkbox'. Using this ID avoids NoSuchElementException.

4fill in blank

hard

Fill both blanks to create a wait that pauses until the CAPTCHA iframe is visible.

Selenium Python

WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.[1], '[2]')))

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

ATAG_NAME

Biframe

CID

Dclass_name

Attempts:

3 left

💡 Hint

Common Mistakes

Using FRAME instead of TAG_NAME causes errors.

Using ID or class_name without correct values.

To wait for an iframe element, use By.TAG_NAME with 'iframe' as the locator value.

5fill in blank

hard

Fill all three blanks to switch to the CAPTCHA iframe, solve it manually, then switch back.

Selenium Python

driver.switch_to.[1](driver.find_element(By.[2], '[3]'))
input('Solve CAPTCHA and press Enter...')
driver.switch_to.default_content()

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

Aframe

BTAG_NAME

Ciframe

💡 Hint

Common Mistakes

Using switch_to.frames (plural) instead of frame (singular).

Using incorrect locator types like id with wrong values.

Use switch_to.frame() with By.TAG_NAME and 'iframe' to switch into the CAPTCHA frame before manual solving.
