Getting error, Spring BeanCreationException: Error creating bean with name 'validateableConstraintsEvaluator' - grails3

Question

I have updated my project from grails2.5.6 to grails3.3.9 and successfully completed unit testing.
While running the integration test I am getting the following Exception.
2019-03-07 18:26:12.169 WARN --- [ main] o.s.test.context.TestContextManager : Caught exception while allowing TestExecutionListener [org.spockframework.spring.SpringMockTestExecutionListener#157b7da6] to process 'before' execution of test method [public void com.mdw360.sec.UserControllerSpec.$spock_feature_0_1()] for test instance [com.mdw360.sec.UserControllerSpec#36f464d8]

I my case I have a folder called acceptance-test where I had some integration test I wanted to execute. I created a acceptanceTest gradle task similar to this one integration-test.gradle.
If the task acceptanceTest was executed, the BeanCreationException was thrown. I had to manually active the spring profile dev
./gradlew acceptanceTest -Dspring.profiles.active=test
The root problem is that some grails global variables (like grailsApplication, messageSource) are not created and are need to run test. To run integration test these global variables must be created or mocked by Grails. Setting spring.profile.active to test creates all these global variables.
