ava-postgres

AVA test fixture providing instant, isolated Postgres databases per test using Docker containers and Postgres template databases. Version 7.3.1 runs on Node >=18, requires peer dependencies ava >=4.3.3 and testcontainers >=10.0.0. Ships TypeScript types. Key differentiator: uses shared workers and database templates for near-zero overhead test isolation, avoiding per-test container spin-up costs. Only dependency is a running Docker instance.
