Spring boot test configuration not override normal configuration well

Question

I have a spring boot application with configuation like this:

src/main/resources/application.yml:

eureka:
  client:
    serviceUrl:
      defaultZone: http://10.254.102.12:1111/eureka/

In my unit test cases, I want to set eureka instance name and change the logging level. src/test/resources/application.yml:

eureka:
  instance:
    appname: item-client-test

logging:
  level: debug

But when I added these additional settings those former settings seems to not work any more. The eureka serviceUrl fallback to default loclahost:8761, so my test failed. When I added my custom eureka serviceUrl to src/test/resources/application.yml, my test goes well.

So I am confused about is this a bug of spring boot or I was not using the right way for my configuration?

AFAIK, spring boot doesn't merge them. It uses the most specific one, the test one. — spencergibb, Jul 12 '17 at 19:42

What you can try, instead, is having two configuration files like:

src/main/resources/application.yml

eureka:
  client:
    serviceUrl:
      defaultZone: http://10.254.102.12:1111/eureka/

and

src/main/resources/application-test.yml

eureka:
  instance:
    appname: item-client-test
  client:
    serviceUrl:
      defaultZone: http://test-server/eureka/
logging:
  level: debug

and run your tests with SPRING_PROFILES_ACTIVE=test mvn test

Spring Boot will look for application-#{environment} config file (so to say) and use it, inheriting from the default (application.yml) config file

Spring boot test configuration not override normal configuration well
