Pgtestdb's template cloning approach to testing is fast | Hacker News

A Hacker News discussion highlighted pgtestdb and Postgres template cloning as a fast way to spin up clean test databases for integration tests.

Commenters also suggested reusable Testcontainers and seeded database snapshots to reduce setup time even further.

The goal is to provision a freshly migrated database for each test or test process while preserving realistic SQL, transaction, and concurrency behavior.

This approach keeps tests close to production behavior, cuts runtime, and catches bugs that mocks often miss.
