Food delivery with Selenium
Filter restaurants, add dishes with quantity steppers, customise a pizza in a modal, handle a replace-cart prompt, add tip and coupon, then watch the order move live and rate it.

Scenarios to automate
Work top to bottom — each one adds a new technique.
- 1
Filters & switch
BeginnerCombine cuisine-* chips, veg-only (role=switch), food-search and restaurant-sort; assert restaurant-count.
- 2
ADD becomes a stepper
Beginneradd-<item> turns into <item>-dec / <item>-qty / <item>-inc; decreasing to 0 brings ADD back.
- 3
Customisation modal
IntermediatePick size-* and topping-* (max 3 — the 4th is disabled); custom-total updates live.
- 4
Replace cart prompt
IntermediateAdding from a second restaurant opens replace-cart-modal; keep-cart vs confirm-replace.
- 5
Coupon rules
IntermediateFEAST50 under ₹299 shows how much more to add; above it caps the discount at ₹100.
- 6
Bill maths
AdvancedVerify bill-items, bill-discount, bill-delivery (free ≥ ₹499), bill-taxes (5%) and bill-total with a tip.
- 7
Live tracking
Advancedorder-status moves Order placed → Preparing → Out for delivery → Delivered every ~3s.
- 8
Rate & reorder
IntermediateAfter delivery, rate-* + submit-rating shows rating-thanks; reorder-<id> refills the cart.
Sample Selenium suite
A working starting point that finds elements every way Selenium can — by role, label, text, id, name, CSS, XPath and data-testid — so you practice them all. Pick your language, switch to data-testid only to compare, or try your own in the Locator Playground.
