Grails 3.3.10: running integration tests Error creating bean with name 'com.cabolabs.security.UserController' - integration-testing

Question

I'm trying to create an integration test for a service and keep receiving a controller, that is totally disconnected from the service test, can't be created. Spending a day or so on everything that might cause the issue, and failing miserably, decided to create a project from scratch and start adding line by line.
So I did:
grails create-app test
grails create-domain-class com.cabolabs.security.User
added username and password String fields
grails generate-app com.cabolabs.security.User
grails create-service com.cabolabs.cloud.BalanceUpdate
grails create-integration-test com.cabolabs.cloud.BalanceUpdate
grails test-app com.cabolabs.cloud.BalanceUpdate -integration
That runs OK, the test fails because of the default code, that is not important.
Then I started to add references to services in the UserController, and the BalanceUpdateService, like mailService from the mail plugin.
The test worked as before.
Then I added this line, which I have extensively used in many controllers of my original project:
def config = grailsApplication.config
With that line, the whole thing felt apart and got the error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.cabolabs.security.UserController': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.cabolabs.security.UserController]: Constructor threw exception; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

My question is, how can I have the config injected to my controllers and make the integration tests work? Thanks.

Answer 1

I just created a project from scratch and added line by line, it seems adding this to the controller, makes the test for the service fail (which are not connected in any way): def config = grailsApplication.config
Since I used that in many controllers, I tested changing it to Holders.config and that actually worked. I'll report this as a bug to Grails Core.
