🛍️ Nova Shop

1Business context

Nova Shop is a direct-to-consumer online store. The business goal is conversion: get signed-in shoppers from browsing to a paid order with as little friction as possible, while applying coupons, tax and shipping correctly and protecting against bad payments.

Login with test users, search/filter/sort products, cart & coupons, a validated checkout, a declined card, order history with cancel and return, a store-manager role and a buggy build.

2Users & roles

• 👤 Shopper (demo_user) — browses, buys, cancels, returns and reorders
• 👤 Store manager (admin_user) — ships and delivers orders and decides returns
• 👤 Locked customer (locked_user) — must be blocked at login
• 👤 Slow-network customer (slow_user) — login takes ~3 s
• 👤 Buggy build (buggy_user) — the same shop with 5 seeded defects

5Business rules & validations

• Valid & invalid loginBeginner

  demo_user / Demo@123 succeeds; wrong password and empty fields show login-error.

• Locked-out userBeginner

  locked_user gets “Sorry, this user has been locked out.”

• Slow loginIntermediate

  slow_user takes ~3s — wait for the URL or product grid, never sleep.

• Route guardBeginner

  Visiting /shop/cart signed out redirects to /shop.

• Search, filter & sortIntermediate

  Assert product-count text, no-results state, and that product-price values are sorted.

• Cart badge & quantitiesIntermediate

  Add/remove from the grid, change qty in the cart, check line-total and totals maths.

• CouponsIntermediate

  SAVE10 = 10% off, FLAT20 = $20 off above $100, anything else is rejected.

• Checkout validationIntermediate

  Submit empty to collect error-* messages; fix them one by one.

• Declined cardAdvanced

  4000 0000 0000 0002 shows payment-error; switch to Cash on delivery and succeed.

• Order historyAdvanced

  Order id on the success page must appear in orders-table after navigation.

• Cancel, return & buy againIntermediate

  Cancel a Processing order in cancel-modal; request a return on a Delivered one (a reason is required); reorder-* refills the cart.

• Store manager roleAdvanced

  admin_user lands on /shop/admin, ships and delivers orders and decides returns; demo_user sees access-denied there.

• Bug huntAdvanced

  buggy_user has 5 seeded defects (sort, search, badge, tax, order total) — write tests that fail for it and pass for demo_user.

• UI vs APIAdvanced

  POST /api/shop/quote prices the same cart; assert subtotal, discount, tax and total match the cart page.

8Watch-outs for automation

• ⚠️Orders live in this browser, so the customer and the manager must use the same browser context — switch user by logging out
• ⚠️slow_user login takes ~3 s — wait for the URL or product grid, never sleep
• ⚠️Cart state persists in the browser; clear storage between tests for isolation
• ⚠️Checkout shows an error summary plus per-field errors — assert both
