wey-gu/py-pglite: PGlite wrapper in Python for testing. Test your app with Postgres just as lite as SQLite.

py-pglite is a Python testing library that wraps PGlite to provide in-memory PostgreSQL functionality for tests. It offers seamless integration with SQLAlchemy and SQLModel, automatic process management, and pytest fixtures for database testing without requiring a full PostgreSQL installation. The library supports FastAPI integration, provides utility functions for database operations, and ensures test isolation with automatic cleanup between test runs.
