How to Test a Food Delivery App: 30 Test Cases from Order to Doorstep
Every food delivery app has the same promise: you tap a button, food shows up at your door. Testing that promise requires covering everything between those two moments search, browse, cart, coupons, payments, tracking, delivery confirmation, ratings, and the dozen things that can go wrong at each step.
This guide provides 30 ready-to-use test cases covering every critical flow in a food delivery app, from opening the app to the food arriving. Each test case is written two ways: the traditional Appium approach (selectors, waits, assertions) and the Vision AI approach (plain English, no code). By the end, you'll have a complete QA checklist you can execute today.
These test cases are based on patterns from production delivery apps processing over a million orders daily in India, including platforms tested with Drizz Vision AI.
For the broader delivery app testing strategy, see our Why Delivery Apps Are the Hardest to Test guide.
How to Read These Test Cases
Each test case is shown in two formats:
Appium (traditional): Python code using selectors, explicit waits, and element assertions. Requires Appium server, platform SDKs, and element inspection setup.
Drizz (Vision AI): Plain English steps that describe what the user sees and does. No selectors, no code, no setup beyond connecting a device.
