Practice app · Checkout Service
A load-testable checkout service with realistic latency that degrades under concurrency, plus a live metrics view.
Your starter code already declares BASE_URL — call the API relative to it.
Objective
Model a traffic mix of 70% search, 20% checkout and 10% login with deterministic selection.
Your task
- 1Set options { vus: 5, iterations: 60 }.
- 2Pick the action from __ITER % 10: 0–6 → search, 7–8 → checkout, 9 → login.
- 3Search: GET BASE_URL + "/perf/search?q=mug"; checkout: GET BASE_URL + "/perf/checkout"; login: POST BASE_URL + "/perf/login" with JSON.stringify({ username: "qa@target.dev", password: "Test@123" }) with Content-Type: application/json.
- 4check status 200 for every request.
Acceptance criteria
- Search, checkout and login are all exercised
- ≥ 60 requests are sent
- At least 60 check() calls pass
