Grails unit testing service with spock mocking functionality -

presently trying test grails service (experience geb functional testing)

trying mock necessary required data service need (e.g. user,etc.) ... no matter how seem declare/initialize domains of interest all appear null in tests methods

i'm trying set required information once, can reused through test methods.

@testfor(reminderservice) @mock([reminder, user, subscriptions, organisation, userorganisation, organisationrole, ref, role, title]) class reminderservicetests extends specification {  @shared user, org, userorg, roleuser, sub, orgrole, ti, refvals, reminder def mailservice   def setup() {     def refsubstatus  = new ref(value: 'current').save()     def refsubpublic  = new ref(value: 'no').save()     def refsubtype    = new ref(value: 'subscription taken').save()     def refremunit    = new ref(value: 'month').save()     def reforgrole    = new ref(value: 'subscriber').save()     def refremmethod  = new ref(value: 'email').save()     def refremtrigger = new ref(value: 'subscription manual renewal date').save()     reminder          = new reminder(user: user,  active: true, amount: 1, unit:refremunit, remindermethod:refremmethod, trigger: refremtrigger, lastran:null).save()     refvals     = [refsubstatus,refsubpublic, refsubtype, refremunit, reforgrole, refremmethod, refremtrigger]     roleuser          = new role(authority: 'basic_user', roletype:'global').save()      ti                = new title(title: "a random title....", impid: uuid.randomuuid().tostring()).save()     sub               = new subscription(name:"a random subscription name",                                          status:refsubstatus,                                          identifier:uuid.randomuuid().tostring(),                                          impid:uuid.randomuuid().tostring(),                                          startdate:new localdate().minusyears(1).todate(),                                          enddate: new localdate().plusmonths(1).todate(),                                          ispublic: refsubpublic,                                          type: refsubtype,                                          renewal: new localdate().minusmonths(3).todate()).save()     org               = new organisation(name: "new org", impid: uuid.randomuuid().tostring()).save()     orgrole           = new organisationrole(sub: sub, roletype: reforgrole, org: org).save()     user              = new user(username: 'j_doe', firstname: "john", lastname: "doe", email: 'example@googlemail.com', defaultdash: org).save()     userorg           = new userorganisation(org: org, user: user, formalrole: roleuser, status: 1).save()     mailservice       = new mailservice() //        mockdomain(ref, refdatavalues) //        mockdomain(title, ti) //        mockdomain(organisationrole, orgrole) //        mockdomain(organisation, org) //        mockdomain(user, user) //        mockdomain(userorganisation, userorg) //        mockdomain(reminder, reminder) }   def "getting subscriptions user"() {     when:     def subscriptions = service.getauthorisedsubsciptionsbyuser(user)      then:     subscriptions != null     subscriptions.size() > 0 } 

everything null, i've tried using mockdomain (see commented out section in setup(), including using setupspec() not quite right)

have tried not using @shared? see now, don't need it. references shared throughout lifecycle of spec, put init code in setup, called before each spec. not seem right. @shared variables internally stored in different instance normal variables, there may kind of mixup. also, might try use setupspec() instead of setup() @shared variables.
