Why automation accelerates testing in Testing Fundamentals - Test Execution Impact

Test Overview

This test simulates an automated test running on a login page. It verifies that automation speeds up testing by quickly opening the browser, entering credentials, clicking login, and checking the welcome message. The test confirms that automation performs these steps faster and more reliably than manual testing.

Test Code - Selenium with unittest

Testing Fundamentals

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 TestLoginAutomation(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()
        self.driver.implicitly_wait(5)

    def test_login(self):
        driver = self.driver
        driver.get('https://example.com/login')

        username_input = driver.find_element(By.ID, 'username')
        password_input = driver.find_element(By.ID, 'password')
        login_button = driver.find_element(By.ID, 'login-btn')

        username_input.send_keys('testuser')
        password_input.send_keys('password123')
        login_button.click()

        welcome_message = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.ID, 'welcome-msg'))
        )

        self.assertEqual(welcome_message.text, 'Welcome, testuser!')

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

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

Execution Trace - 10 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Chrome browser window is open and ready	-	PASS
2	Browser navigates to https://example.com/login	Login page is loaded with username, password fields and login button	-	PASS
3	Find username input field by ID 'username'	Username input field is located	-	PASS
4	Find password input field by ID 'password'	Password input field is located	-	PASS
5	Find login button by ID 'login-btn'	Login button is located	-	PASS
6	Enter 'testuser' into username field	Username field contains 'testuser'	-	PASS
7	Enter 'password123' into password field	Password field contains 'password123'	-	PASS
8	Click the login button	Login form submitted, page starts loading next content	-	PASS
9	Wait up to 10 seconds for welcome message element with ID 'welcome-msg' to appear	Welcome message element is present on page	Check that welcome message text equals 'Welcome, testuser!'	PASS
10	Test ends and browser closes	Browser window is closed	-	PASS

Failure Scenario

Failing Condition: Welcome message element does not appear or text is incorrect

Execution Trace Quiz - 3 Questions

What is the first action the automated test performs?

A Click the login button

B Enter username

C Open the Chrome browser

D Check the welcome message

Key Result

Automated tests speed up testing by performing repetitive steps quickly and consistently, reducing human error and saving time.
