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 adviceSection 1: Beginner-Friendly Websites (0-6 Months Experience)1. SauceDemo (https://www.saucedemo.com/)Best for: Login flows, inventory managementKey Elements:Standard/login error casesProduct sorting functionalityCart managementSample 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_sourcePro 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: pythonfrom 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 verificationProduct search and filteringCheckout process with payment gatewayFramework Practice:Implement Page Object Model (POM)Create utility classes for:Screenshot on failureRandom test data generationEmail validationMobile 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 accountsBill pay schedulingTransaction history validationSecurity Testing Angle:Try negative testing with:SQL injection in login fieldsXSS attempts in contact formsBroken authentication testingSection 3: Advanced Challenges (2+ Years Experience)5. React Shopping Cart (https://react-shopping-cart-67954.firebaseapp.com/)SPA-Specific Challenges:Handling virtualized product listsState management verificationNetwork throttling testsPerformance Testing: javascript// 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 calculationsSlider manipulationDate picker with dynamic calendarsVisual Testing Tip:Use Applitools/Percy to verify positioning after interactions.Section 4: Specialized Testing EnvironmentsAPI + UI IntegrationRecommended Flow:Create user via ReqRes APIVerify in UI using same credentialsPerform actions through both interfacesTools Combination:Postman/Newman for API testsSelenium for UI validationJenkins/GitHub Actions for CI/CDSection 5: Mobile-Specific Demos7. Mobile AngularJS (http://mobileangularui.com/demo/)Hybrid App Patterns:Slide-out menusTouch gesturesOffline mode simulationConclusion: Building Your Practice Plan30-Day Challenge: markdownWeek 1: Master all beginner sitesWeek 2: Build POM framework on intermediate sites Week 3: Create CI pipeline with advanced sitesWeek 4: Combine API+UI+Mobile testing
