Social discovery platform · under NDA
Delivered engagement. Coralsoft designed and built this product end to end; figures below retain their evidence level.
What was in place before we started.
A full backend test suite built from scratch for a Deno-based Supabase Edge Functions API — unit tests, integration tests, schema validation, a production-grade mock layer, and CI/CD quality gates across 13 feature modules.
The client (covered under NDA) operates a social discovery platform for real-time, location-aware interaction — users discover nearby events, check in at venues, connect with attendees, and manage social profiles through a mobile app. The server side is a collection of Supabase Edge Functions: individually deployed, serverless TypeScript handlers behind a shared Hono routing layer, covering auth, events, profiles, venues, photo uploads, Stripe payments, and admin operations.
When Coralsoft joined the project, the backend had no test coverage. The challenge was not simply writing tests — it was building the testing infrastructure that made meaningful tests possible in a non-standard runtime. Edge Functions run on Deno; the natural test runner for TypeScript projects runs on Node. Bridging the two module systems without a transpilation step, mocking the Supabase query builder's fluent API faithfully, and doing all of this without ever touching a live database required deliberate infrastructure work before a single assertion could be written.
The goal was not maximum coverage — it was reliable coverage of the most business-critical paths: auth, event participation, and Stripe webhook processing. The infrastructure built in this engagement makes raising coverage thresholds incrementally straightforward.

Each constraint, and what we did about it.
Outcome, with the source of every figure.
How it was sequenced.
Discovery & architecture
Pure utility logic — phone normalisation, Haversine geofence, age calculation, SMS templates, magic link tokens, env config.
- Unit tests
Core build
Zod contracts tested independently — required fields, conditional rules, format patterns, character limits, date ordering.
- Schema tests
Integrations & data
Full HTTP handler path — real Hono context, real Zod validation, mocked Supabase and external services.
- Integration tests
Hardening & QA
Vitest module aliases map Deno-style ESM import URLs to Node package names at resolution time — allowing Deno TypeScript to run through Vitest in Node mode without a transpilation step.
- Deno-to-Node bridge
Launch & handover
createMockSupabaseClient — a full reproduction of the Supabase JS query builder API as a tree of vi.fn() stubs.
