From 66783e31518edd71af6432da8d9dc71e1e6aff99 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 22 May 2026 02:47:13 +0000 Subject: [PATCH] feat(contracts): versioned schema validation for webhooks + contract test runner MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Establishes a contract-testing framework for Supabase Edge Functions and applies it to the 3 webhook endpoints (product-webhook, webhook-inbound, webhook-dispatcher) with full v1/v2 versioning. Foundation: - _shared/version-dispatch.ts: path-based version resolver (/v1, /v2); defaults to v1 for back-compat. Distinguishes the Supabase mount prefix /functions/v1 from the contract version suffix. - _shared/error-response.ts: dual error builders. V1 preserves the legacy {error, details} 400 shape byte-for-byte (n8n compat). V2 introduces RFC-7807-inspired {code, message, fields[]} at 422 with Content-Type: application/problem+json. Includes a snapshot regression guard test for V1. - _shared/zod-validate.ts: adds parseBodyVersioned() alongside the unchanged parseBodyWithSchema(); dispatches v1/v2 by path. Webhooks (T1): - product-webhook: extracted handler; v1 keeps n8n shape; v2 adds required idempotency_key + metadata.source + strict() + errors_by_sku in response. - webhook-inbound: introduces Zod validation (first time); v1 is lenient (passthrough); v2 requires request_id (uuid) + strict envelope. - webhook-dispatcher: extracted schema to schemas.ts; v1 matches old inline BodySchema; v2 adds required correlation_id + dispatch_options (parallel, timeout_ms). All 3 expose 'export const handler' so unit tests can invoke without binding a port; Deno.serve runs only when import.meta.main is true (prod entry). Test layers: - Deno unit tests (78 cases) cover happy path, missing fields, wrong types, empty values, invalid enums/UUIDs, unknown keys (strict), CORS preflight, auth failure, and version-aware response shape. Sanitizers disabled per test via a small t() wrapper because supabase-js starts internal timers. - Node runner scripts/contract-testing.mjs auto-discovers contract.json manifests and runs a 31-scenario v1/v2 matrix. Modes: --simulate (default, no network, CI-safe), --live (POST against deployment), --baseline (records v1 response hashes). - scripts/check-contract-coverage.mjs reports schema/test/manifest coverage per tier and gates CI on the webhook tier. Exceptions live in scripts/contract-exceptions.json (21 functions, mostly crons + diagnostics). - scripts/generate-contract-stub.mjs scaffolds schemas.ts, index.test.ts and contract.json for new functions — used by T2-T4 PRs. npm scripts: test:contracts[:live|:baseline|:verbose|:deno], check:contract-coverage[:strict], generate:contract-stub. Docs: docs/CONTRACT_TESTING.md explains the pattern and the rollout plan (T0 helpers + T1 webhooks land here; T2 13 public functions, T3 12 crons, T4 ~52 JWT functions follow in subsequent PRs). V1 anti-regression: - error-response.test.ts pins the {error, details} shape with status 400 and Content-Type application/json. - scripts/__contracts__/v1-baseline.json records SHA-256 of v1 responses per scenario; PRs that change v1 must add label 'breaking-v1'. https://claude.ai/code/session_01TZcZo79a7Wwr4rUVtwyfB3 --- docs/CONTRACT_TESTING.md | 113 +++++ package.json | 10 +- scripts/__contracts__/contract.schema.json | 46 ++ scripts/__contracts__/v1-baseline.json | 5 + scripts/check-contract-coverage.mjs | 217 ++++++++++ scripts/contract-exceptions.json | 89 ++++ scripts/contract-testing.mjs | 397 +++++++++++++----- scripts/generate-contract-stub.mjs | 171 ++++++++ .../functions/_shared/error-response.test.ts | 224 ++++++++++ supabase/functions/_shared/error-response.ts | 102 +++++ .../_shared/version-dispatch.test.ts | 166 ++++++++ .../functions/_shared/version-dispatch.ts | 76 ++++ supabase/functions/_shared/zod-validate.ts | 116 +++++ .../functions/product-webhook/contract.json | 82 ++++ .../functions/product-webhook/index.test.ts | 293 +++++++++++++ supabase/functions/product-webhook/index.ts | 228 +++++----- supabase/functions/product-webhook/schemas.ts | 129 ++++++ .../webhook-dispatcher/contract.json | 59 +++ .../webhook-dispatcher/index.test.ts | 199 +++++++++ .../functions/webhook-dispatcher/index.ts | 91 ++-- .../functions/webhook-dispatcher/schemas.ts | 69 +++ .../functions/webhook-inbound/contract.json | 61 +++ .../functions/webhook-inbound/index.test.ts | 214 ++++++++++ supabase/functions/webhook-inbound/index.ts | 166 +++++++- supabase/functions/webhook-inbound/schemas.ts | 73 ++++ 25 files changed, 3138 insertions(+), 258 deletions(-) create mode 100644 docs/CONTRACT_TESTING.md create mode 100644 scripts/__contracts__/contract.schema.json create mode 100644 scripts/__contracts__/v1-baseline.json create mode 100644 scripts/check-contract-coverage.mjs create mode 100644 scripts/contract-exceptions.json create mode 100644 scripts/generate-contract-stub.mjs create mode 100644 supabase/functions/_shared/error-response.test.ts create mode 100644 supabase/functions/_shared/error-response.ts create mode 100644 supabase/functions/_shared/version-dispatch.test.ts create mode 100644 supabase/functions/_shared/version-dispatch.ts create mode 100644 supabase/functions/product-webhook/contract.json create mode 100644 supabase/functions/product-webhook/index.test.ts create mode 100644 supabase/functions/product-webhook/schemas.ts create mode 100644 supabase/functions/webhook-dispatcher/contract.json create mode 100644 supabase/functions/webhook-dispatcher/index.test.ts create mode 100644 supabase/functions/webhook-dispatcher/schemas.ts create mode 100644 supabase/functions/webhook-inbound/contract.json create mode 100644 supabase/functions/webhook-inbound/index.test.ts create mode 100644 supabase/functions/webhook-inbound/schemas.ts diff --git a/docs/CONTRACT_TESTING.md b/docs/CONTRACT_TESTING.md new file mode 100644 index 000000000..692632d5b --- /dev/null +++ b/docs/CONTRACT_TESTING.md @@ -0,0 +1,113 @@ +# Contract Testing for Edge Functions + +This document describes the contract-test pattern adopted in PR +`claude/webhook-contract-tests-swzNU` and the migration roadmap for the +remaining Edge Functions. + +## Why + +The project has ~80 Supabase Edge Functions.
