Using multiple mockFor() in grails 2.2.3 unit test

I want to write a unit test for my controller which uses multiple services inside it. How can I use multiple mockFor() for services? Tnx.

For example using spock for testing:

class ExampleControllerUnitSpec extends Specification {
    def anyService
    def anotherService


    def setup() {
        anyService = Mock(AnyService)
        controller.anyService = anyService

        anotherService = Mock(AnotherService)
        controller.anotherService = anotherService
    }

    def "test"(){
        when:
            controller.action()
        then:
            1 * anyService.doSomething() >> "result"
            3 * anotherService.doSomethingElse() >> "result2"
    }
}
