20 component tests covering Button (variants, disabled state, event handlers) and
ProductCard (rendering, price formatting, sale badge, image fallback). README
documents the full suite: 151 tests across 10 files, how to run, mock patterns,
and what's missing by priority (checkout flow, admin routes, more components).
27 tests covering POST /api/auth/login (9), POST /api/auth/register (9), and
POST /api/webhooks/stripe (11). Routes are tested by importing handlers directly
as functions, no HTTP server needed. Stripe false-positive fixed: thrown error
message now differs from the hardcoded 400 response to verify sanitization.
49 tests for all 10 Zod schemas in validate.ts, 26 tests for auth (hashPassword,
verifyPassword, createSession, getSession, getCurrentUser, deleteSession), 11 for
storage (magic-byte validation, saveImage, deleteImageFile), 9 for email (sendMail
scenarios), and 6 for rate limiting logic.
Adds test harness for the suite:
- vitest.config.ts: happy-dom env, @/* alias, v8 coverage with 70% thresholds
- setup.ts: env vars, global next/headers and next/navigation mocks
- tsconfig.json: IDE alias resolution for test/
- __mocks__/prisma.ts: centralised Prisma mock auto-registered via vi.mock
- fixtures/users.ts, fixtures/orders.ts: typed test data
