Question

我有一个集成测试，我正在测试一些在我的两个域对象之间运行的业务逻辑方法。

因为我有多个测试创建同一组对象以在不同条件下运行我的测试，所以我在设置中创建域对象并在清理中删除它们。

然而，我第二次尝试保存此对象时得到org.springframework.dao.DuplicateKeyException，其中我对该对象所做的唯一更改不是一个单独的字段。看起来先前测试的版本可能会根据下面的消息以某种方式悬挂。

如果我不使用设置和清理，而是在每个测试方法的主体中创建所有对象，则测试通过。

相关代码和错误如下：

import grails.test.mixin.integration.Integration
import grails.transaction.*
import spock.lang.*
import com.grapevine.negotiator2.DomainFactory
@Integration
@Rollback
class AgentSpec extends Specification {
  User u
  Agent a
  Buyer b
  User u2

  def setup() {

    //make two users
    u2 = DomainFactory.makeUser("Pancho", "password", E.SpringAuthority.ROLE_USER)
    u =DomainFactory.makeUser("Gorman","password",E.SpringAuthority.ROLE_USER)
    //make a buyer
    b = DomainFactory.makeBuyer("Sam Jones")
    b.scaleFear = 0.0
    b.scaleGreed = 0.0
    b.save()
    //make an agent
     a = DomainFactory.makeAgent(u)
}

def cleanup() {
    DomainFactory.killUser(u)
    DomainFactory.killUser(u2)
    b.delete(flush: true)
    a.delete(flush:true)
}
void "TestforBadReputation"() {
    given:  "An agent with bad reputation"
    a.reputation=-5.1
    expect: "An agent with a <-5 reputation to be rejected by any buyer"
    a.validate()
    a.save()
    b.respondToRepresentationRequest(a)==E.BuyerAgencyResponse.BadReputation

}
void "TestforAlreadyHasAgent"() {
    given: "An buyer who already has an agent"
    b.agent = a
    b.save()
    a.reputation=5     
    expect: "Buyer rejects agency request"
    a.validate()
    a.save()
    b.respondToRepresentationRequest(a)== E.BuyerAgencyResponse.AlreadyRepresented
}
}

错误：

identifier value was already associated with the session : [com.grapevine.negotiator2.Agent#13]; 
nested exception is org.hibernate.NonUniqueObjectException: A different object

Grails测试问题：设置和清理，不太清理
