Submitting forms in Selenium Python - Practice Problems & Coding Challenges

Challenge - 5 Problems

❓ Predict Output

What is the output of this Selenium Python code snippet?

Consider the following Selenium code that tries to submit a form. What will be printed after execution?

Selenium Python

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument('--headless')
driver = webdriver.Chrome(options=options)
driver.get('data:text/html,<form id="login"><input type="text" name="user"><input type="submit" value="Send"></form>')

form = driver.find_element(By.ID, 'login')
form.submit()
print('Form submitted')
driver.quit()

A Form submitted

B NoSuchElementException

C ElementNotInteractableException

D TimeoutException

💡 Hint

The form element is found and submit() is called directly.

The code finds the form by ID and calls submit() on it. This triggers form submission without errors, so 'Form submitted' is printed.

❓ assertion

intermediate

Which assertion correctly verifies form submission success?

After submitting a form, the page shows a message with id 'success-msg'. Which assertion correctly checks that the message text is 'Success'?

Selenium Python

from selenium.webdriver.common.by import By

message = driver.find_element(By.ID, 'success-msg').text

A assert message == 'Success'

B assert message is 'Success'

C assert message.equals('Success')

D assert message.contains('Success')

💡 Hint

Use Python string equality operator for exact match.

In Python, '==' compares string values correctly. 'is' checks identity, which is not reliable for strings. 'equals' and 'contains' are not valid Python string methods.

❓ locator

advanced

Which locator is best to find the submit button inside a form with id 'signup'?

You want to locate the submit button inside the form with id 'signup'. Which locator is the most precise and reliable?

A By.CLASS_NAME, 'submit-btn'

B By.XPATH, '//input[@type="submit"]'

C By.ID, 'submit'

D By.CSS_SELECTOR, '#signup input[type="submit"]'

💡 Hint

Choose a locator that scopes inside the form and targets the submit input.

Option D uses CSS selector scoped inside the form with id 'signup' and targets input with type submit, making it precise. Option D is too broad and may find other submit inputs. Options A and D rely on attributes that may not exist.

Why does this Selenium form submission code raise ElementNotInteractableException?

Given this code snippet, why does calling click() on the element raise ElementNotInteractableException?

Code: email_input = driver.find_element(By.NAME, 'email') email_input.click()

A The driver is not focused on the input element.

B click() can only be called on form elements, not input elements.

C The input element is hidden (display:none), so click() cannot be called on it.

D The input element has no value, causing the exception.

💡 Hint

Check if the element is visible and interactable before calling click().

The click() method requires the element to be visible and interactable. Here, the input is hidden with display:none, so Selenium raises ElementNotInteractableException.

❓ framework

Which pytest fixture setup is best for testing form submission with Selenium?

You want to write pytest tests that submit forms using Selenium WebDriver. Which fixture setup ensures the browser opens before each test and closes after, with headless mode enabled?

A

import pytest
from selenium import webdriver

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

B

import pytest
from selenium import webdriver
from selenium.webdriver.chrome.options import Options

@pytest.fixture
 def driver():
  options = Options()
  options.add_argument('--headless')
  driver = webdriver.Chrome(options=options)
  yield driver
  driver.quit()

C

import pytest
from selenium import webdriver

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

D

import pytest
from selenium import webdriver
from selenium.webdriver.chrome.options import Options

@pytest.fixture(scope='session')
 def driver():
  options = Options()
  options.add_argument('--headless')
  driver = webdriver.Chrome(options=options)
  yield driver
  driver.quit()

💡 Hint

Use headless mode and open/close browser for each test.

Option B uses headless mode and a fixture with default function scope, so browser opens before each test and closes after. Options B and D miss headless mode or have broader scope. Option B misses headless mode.
