Building and Testing Applications With Micronaut and Testcontainers in IntelliJ IDEA
summary
Shows Micronaut project generation inside IntelliJ, wiring Micronaut + Testcontainers so a MySQL Testcontainer starts for runs and JUnit5 integration tests, and demonstrates a persistent test resources service that keeps containers alive so repeated tests run instantly. Builds a CRUD repo, DTO-backed queries that compile to optimized SELECTs, and live SQL/bean/endpoint tooling in the IDE. Compiles to a native image with ~101 ms startup and ~20 MB resident memory, runs native JUnit tests successfully.
