Supabase-Test – Fast Isolated Postgres DBs for Testing Supabase RLS
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:…
In plain words
Supabase-Test is a testing framework that creates isolated Postgres databases for each test case, designed for validating Supabase row-level security policies. It spins up databases instantly, rolls back automatically after tests, and includes auth simulation through a `.setContext()` method. The tool supports flexible data seeding via SQL, CSV, JSON, or JavaScript, works with Jest, Mocha, and other async test runners, and integrates cleanly with GitHub Actions for continuous integration.
