TestContainers demo

There are 2 services in this demo:

• User service
• Item service

User service uses Postgres and Item service uses Redis respectively and has dependency on User service. Each service has a SpringBootTest which uses non-mocked DB started by TestContainers library.

test-runner module is an example of a framework to start all 2 services and their dependencies together in order to perform end-to-end tests.
