# Integration Test Generator Generate integration tests for: **$ARGUMENTS** (framework defaults to vitest) ## Steps 1. **Identify the integration boundary** — What components are being tested together? - API route + database - Service layer + external API - Multiple services collaborating 2. **Set up test infrastructure**: - Database: use a test database (not mocks) — Prisma with a test schema - External APIs: use MSW (Mock Service Worker) or similar for HTTP mocking - Auth: create test fixtures for authenticated/unauthenticated states 3. **Design test scenarios**: - **Full flow** — request in, response out, verify database state - **Error propagation** — verify errors at one layer surface correctly at another - **Data integrity** — verify relations, cascades, constraints - **Concurrent access** — if relevant, test race conditions 4. **Write tests**: ```typescript import { describe, it, expect, beforeAll, afterAll, beforeEach } from "vitest"; import { prisma } from "@/lib/prisma"; import { createTestUser, cleanupTestData } from "./helpers"; describe("POST /api/orders", () => { let testUser: User; beforeAll(async () => { testUser = await createTestUser(); }); afterAll(async () => { await cleanupTestData(); }); beforeEach(async () => { await prisma.order.deleteMany({ where: { userId: testUser.id } }); }); it("creates an order and updates inventory", async () => { const response = await fetch("/api/orders"
