Supabase-Test – Fast Isolated Postgres DBs for Testing Supabase RLS

Hacker News

Hi HN — we've built a testing framework for Supabase that spins up fast, isolated Postgres databases for each test case. It’s designed to make RLS policies easy to validate with real database state, without global test fixtures or mock auth. Features: - Instant isolated Postgres DBs per test - Automatic rollback after each test - RLS-native testing with `.setContext()` for auth simulation - Flexible seeding (SQL, CSV, JSON, JS) - Works with Jest, Mocha, and any async test runner - CI-friendly (runs cleanly in GitHub Actions) We also published example projects and a free set of tutorials: https://launchql.com/learn/supabase Package: https://www.npmjs.com/package/supabase-test Source + full test suite: https://github.com/launchql/supabase-test-suite Happy to answer questions and get feedback, cheers :)
