對關系受約束的領域類的Grails單元測試

Question

我有一個域名課程

class Door {
    String id
    String url
    Room room

    static hasOne = [lock: DoorLock]

    static mapping = {
        id generator: 'uuid'
    }

    static constraints = {
        url nullable:  false
        room nullable: true 
        lock nullable: true
    }

並且我正在嘗試為此編寫一個簡單的Spock測試（實際上首先沒有任何邏輯，只是為了檢查Grails的模擬功能）。

@TestFor(Door)
class DoorSpec extends Specification {
    protected void setup() {
       mockForConstraintsTests(Door)
    }

    def cleanup() {
    }

    void "test something"() {
       when:
       def door = new Door()

       then:
       true
     }
}

當我運行測試（grails test-app Door）時，它失敗並顯示以下錯誤：

java.lang.IllegalStateException: Method on class [citypoints.Door] was used outside of a Grails application. If running in the context of a test using the mocking API or bootstrap Grails correctly.

但是，當我從Door類中刪除lock nullable: false的約束lock nullable: false ，測試運行正常。

是Grails的錯誤還是我做錯了？

PS試圖在mockForConstraintsTests(Door)之前添加mockDomain(DoorLock) mockForConstraintsTests(Door) =>沒有任何變化

PPS我有Grails 2.3.7和休眠插件“：hibernate：3.6.10.9”

我發現了該錯誤的可重現方案：僅在測試域類時出現錯誤，該域類具有名稱為“ lock”的屬性（任何類型的屬性），並且對該屬性具有約束。 看起來像Grails錯誤。
