From 91845ca4000fed3e5ece0341447cd6e7917cc702 Mon Sep 17 00:00:00 2001 From: Test Date: Wed, 25 Mar 2026 22:43:21 +0100 Subject: [PATCH] Add fixture-driven e2e test for webhook detection, persistence, and webhook_map readback Addresses reviewer xkonjin's request on PR #512 for an end-to-end test proving: 1. extractWebhooks correctly identifies Stripe, edge-function, and realtime patterns 2. Webhook nodes with eventTypes[] survive LadybugDB round-trip 3. webhook_map tool reads back correct data with kind/name filtering Co-Authored-By: Claude Opus 4.6 (1M context) --- .../app/api/stripe/webhooks/route.ts | 16 + .../fixtures/webhook-repo/lib/realtime.ts | 3 + .../supabase/functions/notify/index.ts | 4 + .../integration/webhook-detection.test.ts | 278 ++++++++++++++++++ 4 files changed, 301 insertions(+) create mode 100644 gitnexus/test/fixtures/webhook-repo/app/api/stripe/webhooks/route.ts create mode 100644 gitnexus/test/fixtures/webhook-repo/lib/realtime.ts create mode 100644 gitnexus/test/fixtures/webhook-repo/supabase/functions/notify/index.ts create mode 100644 gitnexus/test/integration/webhook-detection.test.ts diff --git a/gitnexus/test/fixtures/webhook-repo/app/api/stripe/webhooks/route.ts b/gitnexus/test/fixtures/webhook-repo/app/api/stripe/webhooks/route.ts new file mode 100644 index 000000000..e28a987f7 --- /dev/null +++ b/gitnexus/test/fixtures/webhook-repo/app/api/stripe/webhooks/route.ts @@ -0,0 +1,16 @@ +import Stripe from 'stripe'; +const stripe = new Stripe(process.env.STRIPE_SECRET_KEY!); + +export async function POST(request: Request) { + const body = await request.text(); + const sig = request.headers.get('stripe-signature'); + const event = stripe.webhooks.constructEvent(body, sig!, process.env.STRIPE_WEBHOOK_SECRET!); + + switch (event.type) { + case 'checkout.session.completed': + break; + case 'invoice.payment_failed': + break; + } + return new Response(JSON.stringify({ received: true })); +} diff --git a/gitnexus/test/fixtures/webhook-repo/lib/realtime.ts b/gitnexus/test/fixtures/webhook-repo/lib/realtime.ts new file mode 100644 index 000000000..c85afc98f --- /dev/null +++ b/gitnexus/test/fixtures/webhook-repo/lib/realtime.ts @@ -0,0 +1,3 @@ +const channel = supabase.channel('order-updates').on('postgres_changes', { event: 'INSERT', schema: 'public', table: 'orders' }, (payload) => { + console.log(payload); +}); diff --git a/gitnexus/test/fixtures/webhook-repo/supabase/functions/notify/index.ts b/gitnexus/test/fixtures/webhook-repo/supabase/functions/notify/index.ts new file mode 100644 index 000000000..4a7a2a698 --- /dev/null +++ b/gitnexus/test/fixtures/webhook-repo/supabase/functions/notify/index.ts @@ -0,0 +1,4 @@ +Deno.serve(async (req) => { + const { user_id, message } = await req.json(); + return new Response(JSON.stringify({ ok: true })); +}); diff --git a/gitnexus/test/integration/webhook-detection.test.ts b/gitnexus/test/integration/webhook-detection.test.ts new file mode 100644 index 000000000..1ac6bd827 --- /dev/null +++ b/gitnexus/test/integration/webhook-detection.test.ts @@ -0,0 +1,278 @@ +/** + * End-to-end Integration Tests: Webhook/Event Handler Detection + * + * Proves the full chain requested in PR #512 review: + * 1.
