java - 帮助解决失败的 Grails 测试 - 域方法不起作用？

Question

鉴于此服务:

class AchievementsService {

    static transactional = true

    public void onEvent(String eventName, User user) {
        def event = Event.findByName(eventName)
        if (!event) {
            event = new Event(name: eventName, autoConfigured: true)
            event.save()
        }
    }
}

为什么此测试失败:

class AchievementsServiceTests extends GrailsUnitTestCase {
    AchievementsService service
    User user
    protected void setUp() {
        super.setUp()
        service = new AchievementsService()
        user = new User(username:"marty",password: "password")
        mockDomain(User,[user])
    }

    void testThat_given_eventDoesNotExistWhenCallingOnEvent_that_eventIsCreated()
    {
         mockDomain Event       
         service.onEvent "MyEvent", user
         assert Event.count() == 1
    }
}

失败如下:

Assertion failed: 

assert Event.count() == 1
             |       |
             0       false

我一定是在设置中或者在调用 .save() 方法时遗漏了一个步骤，但我看不到它。

您可能会遇到验证失败，请将此代码添加到您的服务中以打印验证错误:

if (!event.save()) { 
  event.errors.each{println it} 
}
