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:

# 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:

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"))
)

Section 2: Intermediate Level (6-18 Months Experience)

3. Automation Exercise (https://automationexercise.com/)

Full E-commerce Suite Including:

• User registration with email verification

• 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/)

Banking-Specific Scenarios:

• Fund transfers between accounts

• Bill pay scheduling

• Transaction history validation

Security Testing Angle:

• Try negative testing with:

  • SQL injection in login fields

  • XSS attempts in contact forms

  • Broken authentication testing

Section 3: Advanced Challenges (2+ Years Experience)

5. React Shopping Cart (https://react-shopping-cart-67954.firebaseapp.com/)

SPA-Specific Challenges:

• Handling virtualized product lists

• State management verification

• Network throttling tests

Performance Testing:

// Puppeteer script to measure load times
const perf = await page.metrics();
console.log(`JSHeapUsedSize: ${perf.JSHeapUsedSize}`);

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

• Offline mode simulation
