Integration tests & testContainers
summary
Shows that using containers during integration tests moves teams from H2 compatibility hacks to running real Postgres/MySQL instances with TestContainers wait strategies and automatic start/stop and cleanup. Demonstrates a Micronaut app built with Gradle, a Gradle Docker plugin that creates multiple JDK image variants and publishes registries, and Flyway migration testing to catch destructive schema changes. Notes Docker Compose port race conditions and randomized ports, and includes working examples: mock OpenAPI server, MySQL 11.06 and Postgres containers, plus a few demo network failures.
