如何在grails / spock单元测试

Question

 void "test saveSupervisor action"() {
    setup:
    def testUser = new User()
    controller.userAuthService = [currentUser: testUser]


    expect:
    //User supervisor= new User()
    User supervisor= new User(username: "sp123456",password: "pwd")
    supervisor.save()
    println "spv************ : "+ supervisor

    when:"When User NAME Given"
    controller.params.username = "sp123456"
    controller.saveSupervisor()

    then:
    response.redirectUrl.endsWith '/showsupervisor/id'
}`---controller code----`
   @Secured("hasRole('ROLE_ADMIN') and (hasRole('ROLE_SUPERVISOR') )")
@Transactional
def saveSupervisor(User userInstance) {


    if (userInstance == null) {
        notFound()
        return
    }

    if (userInstance.hasErrors()) {
        respond userInstance.errors, view:'create'
        return
    }


    userInstance.save flush:true

    def spvRole = Role.findByAuthority('ROLE_SUPERVISOR')



    UserRole.create userInstance, spvRole , true



}

但我认为我做错了 我有这些用户角色，ROLE_SUPERVISOR，ROLE_ADMIN 当具有role_supervisor和role_admin的用户登录到应用程序时，只有他被授予访问操作savSupervisor（）的权限。如何在spock测试中捕获登录用户的角色？我想测试用户是否使用角色ROLE_SUPERVISOR＆＃34;和＆＃34;然后，只有ROLE_ADMIN才能访问saveSupervisor（）方法。我正在使用春季保安，请帮助我。
