Due to ports exposed for a test containers (part of DB_URL) are variable (to allow concurrent tests executions and to avoid conflicts with
existing containers) the expected variables are set after the test container being initialized directly from TestContainer wrapper artifact
...
The database schema initialization is performed by Spring framework (same way for both runtime and testing) using schema.sql file.
See https://docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto-database-initialization
Test data
Spring framework allows data setting for testing using @Sql annotation.
