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]

Controller

@Transactional(readOnly = true)
class UserController 

 def userCache
 def springSecurityService
 def utilityService

 static allowedMethods = [save: "POST", update: "PUT", delete: "DELETE"]


 def create() 
 List<Role> roles = Role.list()
 Map roleMap = [:]
 roles.each role -> roleMap[role] = false 
 render view: 'create', model: [userCO: new SaveUserCO(), roleMap: roleMap]

TestClass

import grails.gorm.transactions.Rollback
import grails.testing.mixin.integration.Integration
import org.springframework.beans.factory.annotation.Autowired
import spock.lang.Specification

@Rollback
class UserControllerSpec extends Specification

 def cleanup()

 when:
 controller.request.method='POST'
 controller.create()

 then:
 assert controller.modelAndView.viewName == '/user/create'
 assert controller.modelAndView.model.size() == 2
 assert controller.modelAndView.model.roleMap.size() == 0
 assert controller.modelAndView.model.userCO != null
 

 void "test create render correct view and model when role exists"()
