Test Overview

This test checks if a web form accepts input correctly and submits successfully. It verifies that form handling works as expected, which is common because forms collect user data in many applications.

Test Code - Selenium

Selenium Python

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import unittest

class TestFormHandling(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()
        self.driver.get('https://example.com/contact')

    def test_form_submission(self):
        driver = self.driver
        # Wait for form fields to be present
        WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, 'name')))
        # Fill in the form
        driver.find_element(By.ID, 'name').send_keys('Alice')
        driver.find_element(By.ID, 'email').send_keys('alice@example.com')
        driver.find_element(By.ID, 'message').send_keys('Hello, this is a test message.')
        # Submit the form
        driver.find_element(By.ID, 'submit-btn').click()
        # Wait for confirmation message
        confirmation = WebDriverWait(driver, 10).until(
            EC.visibility_of_element_located((By.ID, 'confirmation'))
        )
        # Assert confirmation text
        self.assertIn('Thank you', confirmation.text)

    def tearDown(self):
        self.driver.quit()

if __name__ == '__main__':
    unittest.main()

Execution Trace - 9 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Browser is open at 'https://example.com/contact' page with the form visible	-	PASS
2	Waits for the 'name' input field to be present using WebDriverWait	'name' input field is present and ready for input	Presence of element with ID 'name'	PASS
3	Fills 'name' field with 'Alice'	'name' field contains text 'Alice'	-	PASS
4	Fills 'email' field with 'alice@example.com'	'email' field contains text 'alice@example.com'	-	PASS
5	Fills 'message' field with 'Hello, this is a test message.'	'message' textarea contains the test message	-	PASS
6	Clicks the submit button with ID 'submit-btn'	Form is submitted, page processes the submission	-	PASS
7	Waits for confirmation message with ID 'confirmation' to be visible	Confirmation message is visible on the page	Visibility of element with ID 'confirmation'	PASS
8	Checks that confirmation text contains 'Thank you'	Confirmation message text includes 'Thank you'	Assert 'Thank you' in confirmation.text	PASS
9	Test ends and browser closes	Browser is closed	-	PASS

Failure Scenario

Failing Condition: The confirmation message does not appear after form submission

Execution Trace Quiz - 3 Questions

Test your understanding

What does the test verify after submitting the form?

AThat a confirmation message with 'Thank you' appears

BThat the form fields are cleared

CThat the page URL changes

DThat the submit button is disabled

Key Result

Testing form handling is essential because forms are the main way users interact with web apps to submit data, so verifying input and submission ensures the app works correctly.
