Caccept

Dprompt

Attempts:

3 left

💡 Hint

Common Mistakes

Using driver.switch_to.prompt() which is invalid.

Using alert.write() instead of send_keys.

Using alert.confirm() instead of accept().

Switch to alert, send keys, then accept it using alert.accept().

Practice

1. What is the main purpose of handling a prompt alert with text input in Selenium?

easy

A. To scroll the webpage automatically

B. To enter text into a popup alert and accept it

C. To click a button on the webpage

D. To take a screenshot of the alert

Solution

1. Step 1: Understand prompt alerts

   Prompt alerts allow users to enter text in a popup box on the webpage.

2. Step 2: Handling prompt alerts in Selenium

   Selenium can switch to the alert, send text input, and accept it to proceed.

3. Final Answer:

   To enter text into a popup alert and accept it -> Option B

4. Quick Check:

   Prompt alert = text input + accept [OK]

Hint: Prompt alert means input text then accept [OK]

Common Mistakes:

• Confusing prompt alert with simple alerts
• Trying to send keys without switching to alert
• Ignoring the accept() step after input

2. Which Selenium Python code snippet correctly sends text 'hello' to a prompt alert and accepts it?

easy

A. driver.send_keys('hello')
alert.accept()

B. alert = driver.find_element_by_id('alert')
alert.send_keys('hello')
alert.accept()

C. alert = driver.switch_to.alert
alert.send_keys('hello')
alert.accept()

D. alert = driver.switch_to.alert
alert.dismiss()
alert.send_keys('hello')

Solution

1. Step 1: Switch to alert correctly

   Use driver.switch_to.alert to access the alert object.

2. Step 2: Send keys and accept alert

   Call send_keys('hello') then accept() to input text and confirm.

3. Final Answer:

   alert = driver.switch_to.alert alert.send_keys('hello') alert.accept() -> Option C

4. Quick Check:

   switch_to.alert + send_keys + accept = correct [OK]

Hint: Always switch_to.alert before sending keys [OK]

Common Mistakes:

• Using find_element instead of switch_to.alert
• Calling dismiss() before send_keys
• Sending keys without switching to alert

3. What will be the output of this Selenium Python code if the prompt alert expects a name and you input 'Alice'?

alert = driver.switch_to.alert
alert.send_keys('Alice')
alert.accept()
result = driver.find_element(By.ID, 'result').text
print(result)

medium

A. Alert dismissed without input

B. No alert found error

C. Empty string printed

D. Hello Alice! Your input was received.

Solution

1. Step 1: Input text and accept alert

   The code sends 'Alice' to the prompt alert and accepts it, so input is registered.

2. Step 2: Retrieve result text from page

   The page updates an element with ID 'result' to show a greeting including the input.

3. Final Answer:

   Hello Alice! Your input was received. -> Option D

4. Quick Check:

   Input 'Alice' + accept = greeting message [OK]

Hint: Accepted prompt input updates page text [OK]

Common Mistakes:

• Expecting error without alert present
• Not retrieving updated element text
• Assuming alert dismiss clears input

4. Identify the error in this Selenium Python code snippet handling a prompt alert:

alert = driver.switch_to.alert
alert.accept()
alert.send_keys('Test')

medium

A. send_keys called after accept, alert no longer available

B. Missing import for Alert class

C. Incorrect locator used for alert

D. No error, code works fine

Solution

1. Step 1: Understand alert lifecycle

   Calling accept() closes the alert, so it cannot receive input afterward.

2. Step 2: Correct order for input and accept

   send_keys() must be called before accept() to input text successfully.

3. Final Answer:

   send_keys called after accept, alert no longer available -> Option A

4. Quick Check:

   accept() closes alert, no send_keys after [OK]

Hint: Send keys before accept to avoid alert closed error [OK]

Common Mistakes:

• Calling accept before send_keys
• Ignoring alert closure after accept
• Assuming alert object persists after accept

5. You want to test a prompt alert that asks for user age and rejects empty input. Which Selenium Python code correctly handles this scenario and verifies the rejection message?

hard

A. alert = driver.switch_to.alert
alert.send_keys('')
alert.accept()
msg = driver.find_element(By.ID, 'error').text
assert msg == 'Input required'

B. alert = driver.switch_to.alert
alert.dismiss()
msg = driver.find_element(By.ID, 'error').text
assert msg == 'Input required'

C. alert = driver.switch_to.alert
alert.send_keys('25')
alert.dismiss()
msg = driver.find_element(By.ID, 'error').text
assert msg == 'Input required'

D. alert = driver.switch_to.alert
alert.send_keys('')
alert.dismiss()
msg = driver.find_element(By.ID, 'error').text
assert msg == 'Input required'

Solution

1. Step 1: Send empty input and accept alert

   Send empty string to prompt and accept to simulate empty input submission.

2. Step 2: Verify error message on page

   Check the element with ID 'error' for the rejection message 'Input required'.

3. Final Answer:

   Send empty input + accept + assert error message -> Option A

4. Quick Check:

   Empty input + accept triggers error message [OK]

Hint: Send empty string then accept to test input validation [OK]

Common Mistakes:

• Dismissing alert instead of accepting
• Not sending any input before accept
• Checking wrong element for error message
