The Ultimate Guide to Demo Websites for Selenium Automation Testing

 Introduction: Why Practice on Demo Websites?

In today's fast-paced software development world, automation testing skills are in high demand. Whether you're preparing for a QA interview, upskilling your team, or building a test automation framework from scratch, having access to reliable, free demo websites is invaluable.


This comprehensive guide covers 50+ demo websites categorized by:

  • Skill level (Beginner → Advanced)

  • Testing type (Web, Mobile, API)

  • Technology stack (React, Angular, JQuery)

  • Real-world scenarios (E-commerce, Banking, SaaS)


We've also included:


✔ Pro tips for maximizing each demo site
✔ Common interview questions per website
✔ Recommended test scenarios
✔ Troubleshooting advice



Section 1: Beginner-Friendly Websites (0-6 Months Experience)

1. SauceDemo (https://www.saucedemo.com/)


Best for: Login flows, inventory management

Key Elements:

  • Standard/login error cases

  • Product sorting functionality

  • Cart management


Sample Test Case:

 python


# Verify locked_out_user cannot login
driver.find_element(By.ID, "user-name").send_keys("locked_out_user")
driver.find_element(By.ID, "password").send_keys("secret_sauce")
driver.find_element(By.ID, "login-button").click()
assert "Epic sadface" in driver.page_source

Pro Tip: Use this site to practice Data-Driven Testing by creating CSV files with different user credentials.



2. The Internet (https://the-internet.herokuapp.com/)


Modules Worth Testing:

  • File Upload (Great for send_keys() practice)

  • Dynamic Loading (Perfect for explicit waits)

  • JavaScript Alerts (Alert handling techniques)


Interview Question:
"How would you handle a dynamically generated element that takes 10+ seconds to load?"


Answer Framework:

 python


from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

element = WebDriverWait(driver, 15).until(
    EC.presence_of_element_located((By.ID, "slow-loader"))
)

  • Product search and filtering

  • Checkout process with payment gateway


Framework Practice:

  • Implement Page Object Model (POM)

  • Create utility classes for:

    • Screenshot on failure

    • Random test data generation

    • Email validation


Mobile Testing Bonus:
The site is responsive - perfect for practicing Appium tests on browser stacks.


4. ParaBank (https://parabank.parasoft.com/)

6. JQuery UI (https://jqueryui.com/)


Complex Interaction Tests:

  • Drag and drop with offset calculations

  • Slider manipulation

  • Date picker with dynamic calendars


Visual Testing Tip:
Use Applitools/Percy to verify positioning after interactions.


Section 4: Specialized Testing Environments


API + UI Integration

Recommended Flow:

  1. Create user via ReqRes API

  2. Verify in UI using same credentials

  3. Perform actions through both interfaces

Tools Combination:

  • Postman/Newman for API tests

  • Selenium for UI validation

  • Jenkins/GitHub Actions for CI/CD


Section 5: Mobile-Specific Demos

7. Mobile AngularJS (http://mobileangularui.com/demo/)

Hybrid App Patterns:

  • Slide-out menus

  • Touch gestures
