Replace OAuth2 client provder properties in Spring Boot for testing - spring

Question

Our Spring Boot application acts as an OAuth2 client and, by default, contacts the identity provider's (here: Keycloak) endpoint for its "OAuth Well-Known Configuration Information" configured by this Spring property:
spring.security.oauth2.client.provider.keycloak.issuer-uri
The problem is, that any #SpringBootTest then also attempts to connect to such a server which fails immediately. So, for integration testing, I'd like to replace the above issuer-uri with the propeties jwk-set-uri, authorization-uri and token-uri which don't prevent the application from starting.
So, I created the following application.yml which does its job but I think it's not very obvious for other team members what happens here.
spring:
security:
oauth2:
client:
registration:
keycloak:
provider: keycloak
client-id: ${app.authentication.client-id}
client-secret: ${app.authentication.client-secret}
authorization-grant-type: authorization_code
redirect-uri: "{baseUrl}/login/oauth2/code/keycloak"
scope: openid
provider:
keycloak:
user-name-attribute: preferred_username
---
spring:
config:
activate:
on-profile: default
security:
oauth2:
client:
provider:
keycloak:
issuer-uri: ${app.authentication.server-url}
---
spring:
config:
activate:
on-profile: integration-test
security:
oauth2:
client:
provider:
keycloak:
jwk-set-uri: ${app.authentication.server-url}
authorizationUri: ${app.authentication.server-url}
tokenUri: ${app.authentication.server-url}
Is there soem other apporach how to diable the issuer-uri and replace it by the three above properties when testing?
