[main] INFO org.springframework.test.context.support.AbstractContextLoader - Could not detect default resource locations for test class [com.FooRepositoryTest]: no resource found for suffixes {-context.xml, Context.groovy}.

Answer 1

Are there any loggers specific to package structure specified in your YAML? If yes, then those will override the ROOT value.
