How to test Grails service using Spock?

Question

I have a EncouragementService.groovy with following method

  class EncouragementService {
   def stripePaymentService 

   def encourageUsers(List&l         


        

Answer 1

Use the build-test-data plugin to build the users.

@TestFor(EncouragementService)
@Build(User)
class EncouragementServiceSpec extends Specification {

  def "encourage users does x"() {
    given:
    def users = createUsers();

    when:
    service.encourageUsers(users)  

    then:
    // assert something
  }

  def createUsers(){
    [User.build(), User.build(), User.build()]
  }
}

I've also made a couple of changes to the code to make it a proper spock specification. Your test has to extend Specification and you might want to familiarize yourself with Spock's keywords.
