spring-boot-jpa

问题 I have a project with 2 DataSources. One is for PostgreSQL and other is for ClickHouse. No problem so far. I intend to use ClickHouse with native SQL via JDBC only.

问题 Here https://stackoverflow.com/a/52968130/10894456 is well explained why @DataJpaTest @SpringBootTest shouldn't be mixed in one application. But barely explained the case when anyway need to test every layer of MVC SpringBoot application (from my point it's natural to test not only one or only another layer but both and even all layers, isn't it?)
