Ecommerce websites lose customers fast when core features break. Think login issues, failed payments, or an unresponsive cart. Bugs in these areas directly cut into revenue. QA teams can’t afford to skip key scenarios anymore. A basic test suite doesn’t work when users expect fast, secure, and mobile-friendly experiences.

This guide lists over 50 practical test cases for ecommerce websites that cover both functional and non-functional checks. It’s built for QA professionals and product teams who want to improve coverage where it actually matters. From user registration to payment gateway testing, every test case is grouped to simplify planning and execution.

Whether you’re building from scratch or fine tuning your ecommerce testing checklist, these examples will help you catch issues before users do. And if you’re looking to scale faster, BotGauge helps teams automate thousands of test cases across UI, API, and user flows without writing complex code. 

Let’s look at what to test, how to test it, and why these checks can’t be ignored.

Functional Ecommerce Test Cases

Most bugs in ecommerce websites start with broken flows in registration, product browsing, cart management, or search. These are the core interactions users rely on every day. A missed bug here doesn’t just frustrate, it kills conversions. 

Below are 23 must-test cases for ecommerce websites covering basic functionality.

User Registration & Login

One of the first checkpoints in your QA plan should be user login and account creation. These flows often fail under minor edge cases, affecting user trust and retention. This section includes test cases for ecommerce website flows that verify authentication and session behavior.

1. Register with valid details

Verify that the system accepts valid inputs like name, email, and a strong password. The form should redirect to the welcome or dashboard page.

2. Register with invalid email format

The form should reject inputs such as user@domain or user@.com. Error handling must trigger with a visible message.

3. Check password strength

Passwords should meet conditions like 8+ characters, a number, a capital letter, and a symbol. Weak inputs should trigger a warning.

4. Login with correct credentials

Confirm that a registered user can log in without delay. The session should be maintained during activity.

5. Login with incorrect credentials

Try logging in with wrong email or password combinations. The system should deny access and display a secure error message.

6. Forgot password flow

From entering an email to resetting the password, the entire reset flow should work smoothly with proper validations and token expiration.

7. Remember me functionality

This is a common feature in most ecommerce test cases. Test if the checkbox preserves session data across browser restarts.

8. Session timeout validation

Sessions should expire after inactivity. Users must be redirected to the login page once the session ends, improving security.

These are foundational test cases for ecommerce website login flows. Bugs here can break the user experience before a product is even added to cart.

Product Search & Filtering

Product discovery depends on how well your site handles search and filters. These test cases for ecommerce website search functions cover keyword handling, filtering accuracy, and pagination logic. A single failure here leads to poor conversions.

9. Search by keyword

Use exact or partial product names. Results must return quickly with accurate matches and correct pricing.

10. Search with no results

Enter an irrelevant or misspelled word. The page should show a clean “no results” message while maintaining layout integrity.

11. Category-based filtering

Select categories like electronics or accessories. The filter must update results instantly and only show products within the chosen group.

12. Sort by price, popularity, and rating

Apply sort options one at a time. Product listings should reorder correctly while keeping visual consistency.

13. Combine filters effectively

Apply brand, price, and availability filters together. Confirm that result logic works without conflicts or data gaps.

14. Paginate search results

Navigate across multiple result pages. Filters and sort preferences must stay intact as you scroll or switch pages.

These checks belong in every solid ecommerce testing checklist and help validate a reliable product search experience across user journeys.

Product Detail Page

The product page is where buyers finalize decisions. These test cases for ecommerce websites help validate visuals, dynamic pricing, and review logic. Every ecommerce testing checklist must include this section to prevent user drop-offs.

15. Zoom and gallery display for product images

Test zoom on hover or click. Thumbnails must load the right preview. Check responsiveness, alt text, and mobile gestures.

16. Price, discount, and stock display

Ensure real-time updates for pricing and stock. Discounts should reflect correctly with crossed MRP, active price, and availability badge.

17. Product variant selection (size, color)

Switching variants must update stock, price, and image. Unavailable options should be disabled or labeled as out-of-stock.

18. Reviews and ratings display

Validate average rating, count, and review order. Spam or duplicate reviews must be filtered. Load more should trigger via pagination or scroll.

19. Add to wishlist

Only logged-in users should add items. Confirm backend call, wishlist sync, and count updates across sessions.

These ecommerce test cases ensure all product interactions work across frontend and backend and should never be skipped in your ecommerce testing checklist.

Shopping Cart

A broken cart means a broken funnel. These test cases for ecommerce website help confirm cart logic, item updates, and subtotal validation. They’re a key part of any reliable ecommerce testing checklist.

20. Add item to cart

Add a product from the listing or product page. Confirm it reflects instantly in the cart with correct title, quantity, and subtotal.

21. Remove item from cart

Clicking the remove icon should update the UI immediately. Test edge cases like removing the last item or a zero-quantity bug.

22. Update item quantity

Change product quantity and verify automatic recalculation of subtotal. Test max quantity limits and stock validation.

23. Cart persistence across sessions

Log out or refresh the session. The cart should retain its contents using cookies or local storage for guest users and DB sync for logged-in users.

These ecommerce test cases reduce friction in the most sensitive part of the user journey. The purchase decision point.

Checkout & Payment Test Cases

Checkout Flow

Checkout is where most users abandon their carts. These test cases for ecommerce website ensure every step from address input to shipping logic works without failure. Add them to your ecommerce testing checklist to prevent conversion loss.

24. Apply valid and invalid coupon codes

Check how the system handles working, expired, and misformatted coupon entries. Validate backend logic, discount rules, and UI feedback.

25. Tax and shipping calculation

Input different pin codes or country selections. The total must auto-update with accurate tax and shipping costs based on user location.

26. Add or update billing and shipping address

Test address form validation. Fields like zip code, phone, and city should trigger errors on invalid input and allow edit before confirmation.

27. Guest checkout process

Users must be able to complete checkout without logging in. Test session tracking, data validation, and final order summary.

28. Logged-in checkout flow

Saved address and payment data should auto-fill. Verify that changes to address or quantity reflect immediately in the summary.

29. Select shipping method

Test toggling between options like standard and express. UI should reflect price changes and estimated delivery times.

These ecommerce test cases focus on stability in high-friction areas of the checkout process, which is essential for reducing drop-offs.

Payment Gateway

Payment is where risk peaks. These test cases for ecommerce website focus on verifying different payment flows, failure handling, and post-order behavior. No ecommerce testing checklist is complete without these.

30. Support multiple payment methods

Verify Credit/Debit Cards, UPI, wallets, and net banking. Each method should process successfully and respond with transaction ID.

31. Handle invalid card details

Use expired or fake card numbers. The system should block the payment, return a clear error, and not store card data.

32. Process successful payments

Complete a real or sandbox transaction. The system should show a success message, update the order status, and clear the cart.

33. Handle payment failures

Force a failed transaction via timeout or card decline. Ensure the order isn’t created and the cart remains intact.

34. Initiate refund request

Submit a refund from the user dashboard. Test API calls to the gateway, refund status update, and email notification.

35. Send order confirmation

On success, confirm that order summary is displayed, email receipt is sent, and invoice is generated in the user account.

These ecommerce test cases ensure payment flows are stable, secure, and integrated properly, a critical part of any ecommerce testing checklist.

Non-Functional Ecommerce Test Cases

These are the failures users don’t report — they just leave. Every ecommerce testing checklist should include these test cases for ecommerce website covering speed, security, accessibility, and device compatibility. Here’s how to structure them.

Performance & Load Test Cases

Slow sites cost money. Performance issues damage trust and lower conversion. These ecommerce test cases ensure your platform handles traffic and loads quickly.

36. Homepage load under 2 seconds

Measure TTFB (Time To First Byte) and full load using tools like GTmetrix. Target under 2 seconds on desktop and mobile.

37. Handle peak traffic loads

Simulate 500+ users using JMeter or LoadNinja. Validate server response time, API failure rate, and memory usage.

38. Slow network handling

Throttle to 3G or lower. Check if the system displays loading indicators, doesn’t timeout, and loads progressively.

These test cases for ecommerce websites ensure your speed and uptime don’t collapse when traffic spikes.

Security Test Cases

Ecommerce sites handle sensitive user data. One mistake can lead to data leaks or fraud. These test cases for ecommerce website focus on threat prevention and secure handling of forms, sessions, and transactions. Every ecommerce testing checklist must include them.

39. HTTPS enforcement on all pages

Verify that all pages (especially login, cart, and checkout) load over HTTPS. Redirect HTTP requests automatically and block insecure content.

40. SQL injection validation

Enter SQL payloads (‘ OR 1=1 –) into login, search, or URL params. The app should not return any database error or allow bypassing auth.

41. Cross-site scripting (XSS) test

Input <script> or other JS tags into review fields, search bars, and URLs. Ensure no script is executed in the browser.

42. Session management validation

Log in, log out, and attempt back-button access. Session cookies should expire on logout, and access to secure pages should be blocked.

These ecommerce test cases prevent financial and privacy risks and protect your brand from reputational damage.

Accessibility & Usability Test Cases

Accessibility is not optional — it’s expected. These test cases for ecommerce website ensure your store works for all users, including those using assistive tech. A good ecommerce testing checklist must verify keyboard support, readable text, and proper screen reader behavior.

43. Tab and keyboard-only navigation

Navigate the full site using just the keyboard. Focus should move logically, and all buttons/links must be accessible via Tab, Enter, and Space.

44. Screen reader support

Test key flows (login, cart, checkout) using screen readers like NVDA or VoiceOver. All actionable elements must have correct labels and ARIA roles.

45. Color contrast and font scaling

Check font size legibility and contrast ratios (minimum 4.5:1) using WCAG tools. Zooming up to 200% should not break layout or hide content.

These ecommerce test cases help ensure your site meets accessibility standards and delivers a consistent experience for everyone.

Compatibility Test Cases

Cross-device and cross-browser consistency is non-negotiable. These test cases for ecommerce website ensure your UI and key workflows behave as expected across environments. Include them in your ecommerce testing checklist before every release.

46. Cross-browser behavior validation

Test on Chrome, Firefox, Safari, and Edge (latest two versions). Ensure all core flows—login, cart, checkout—render identically with no layout or script issues.

47. Mobile responsiveness and touch interactions

On mobile and tablets, validate UI scaling, button tap areas, image swiping, and cart interactions. Content must adapt without overlap or cutoff.

48. Orientation and zoom functionality

Rotate devices between portrait and landscape. Zoom to 200%. The layout should remain stable, and no elements should shift or disappear.

These ecommerce test cases protect the customer experience across devices and browsers, which directly impacts bounce and retention.

Edge Cases & Regression Test Cases

Missed edge cases often lead to hidden bugs. Regression issues break previously working features. These test cases for ecommerce website focus on validating rare interactions and ensuring existing flows stay intact after updates. Any reliable ecommerce testing checklist should include them.

Edge & Regression Test Cases

49. Preserve cart after session logout

Log in, add items, then log out and back in. Verify the cart remains unchanged for logged-in users or is restored via cookies for guests.

50. Duplicate product in cart behavior

Add the same item multiple times. The quantity should increment, not create separate entries, and subtotal must update correctly.

51. Out-of-stock scenario handling

Try checking out with a product that just went out of stock. The system should block the transaction and notify the user clearly.

52. Invalid product URL or ID

Manually edit the product URL with a non-existent ID. The site must show a 404 or error message without breaking layout.

53. Broken image and alt text test

Force an image load failure (e.g., by renaming the file on the server). A fallback image or alt text must appear.

54. Regression after feature update

After adding a feature like a promo code field, verify old flows like checkout, summary, and cart remain unaffected.

55. Product availability confirmation post-order

Complete an order and attempt to reorder the same item. Confirm that availability and quantity are validated in real time again.

These ecommerce test cases help avoid silent failures that typically go unnoticed in rushed release cycles.
