Testing APIs & Dockerized Postgres
Closing out the REST & Database arc: how to actually verify your API by hand, then how to run a real database locally without installing Postgres directly on your machine.
Learning objectives
- Beginner: Manually exercise an API's endpoints with Postman to confirm request/response shapes before writing automated tests.
- Intermediate: Run a real Postgres instance locally via Docker instead of relying on an in-memory substitute like H2.
- Advanced: Write a MockMvc-based test that verifies both the HTTP contract and the underlying persistence behavior together.
