Erro no teste:

Rodei o AutenticacaoControllerTest e o resultado deu OK (verdinho), mas no log encontrei o seguinte erro:

2022-04-23 12:45:08.689 ERROR 18444 --- [gistrationTask1] o.s.s.s.TaskUtils$LoggingErrorHandler    : Unexpected error occurred in scheduled task

java.lang.IllegalStateException: couldn't determine local port. Please set spring.boot.admin.client.instance.service-base-url.

Para resolver, foi só colocar no application-test.properties:

# admin
spring.boot.admin.client.enabled=false
