Grails的構建測試數據插件 - 調用DomainObject.build（）時MissingMethodException

Question

東桑西移

調用MyDomainObject.build（）通過生成測試數據的插件時，我收到以下錯誤在我的單元測試：

異常

  groovy.lang.MissingMethodException: No signature of method: us.maponline.pesticide.PesticideProfile.addToApplicators() is applicable for argument types: (us.maponline.pesticide.PesticideApplicator) values: [us.maponline.pesticide.PesticideApplicator : null]

      | Completed 1 unit test, 1 failed in 5289ms 

每堆棧跟蹤，這是buildtestdata插件代碼內發生。看起來，我的類PesticideApplicator在添加到PesticideProfile類時是空的。

當我要傳遞給PesticideProfile時，我要求構建的類是否爲null，這怎麼可能？

源代碼

測試用例

  @TestFor(PesticideLogService) 
      @Build([PesticideLog,PesticideApplicator,PesticideProfile]) 
      class PesticideLogServiceTests 
      { 
       void testSaveLog() { 

        PesticideApplicator applicator = PesticideApplicator.build() 

        def result = service.createLog(applicator, new Date()) 

        result.errors.each { 
         log.info "got an error. field = $it.field, message:$it.defaultMessage, rejected value = $it.rejectedValue " 
        } 

        assert result: 'no result returned' 
        assert result.success: 'save failed' 
        assert result.result instanceof PesticideLog: "result was not PesticideLog" 

        assert applicator.user.pesticideLogs.size() > 0 : 'expected at least on log to be created.' 

       } 

      } 

PesticideProfileLog

  class PesticideProfile 
      { 

       def User user 
       String companyName 

       static constraints = { 
       } 

       static belongsTo = User 
       static hasMany = [sites: PesticideSite, applicators: PesticideApplicator] 

      } 

PesticideApplicator

  class PesticideApplicator 
      { 

       String firstName 
       String lastName 
       String company 
       PesticideApplicatorLicense licenseType 
       Phone phoneNumber 

       static belongsTo = [profile:PesticideProfile] 

       static constraints = { 
        company blank: false, maxSize: 55 
        firstName blank: false, maxSize: 55 
        lastName blank: false, maxSize: 100 
        phoneNumber nullable: true 
       } 

       static mapping = { 
        licenseType length: 55 
       } 

       def getUser(){ 
       profile?.user 
      } 

      } 

感謝您的幫助！

該問題是由構建測試數據插件嘗試在PesticideApplicator中設置用戶的值引起的。問題是，的getUser（）不是一個領域，它只是一個工具幫助：

... 
    def getUser(){ 
    profile?.user 
    } 
    ... 

刪除getUser()從PesticideApplicator解決了這個問題。

這就是說，我仍然喜歡幫助者方法來訪問用戶（很好，不要讓我的代碼知道另一個類的內部）。標記方法@Transient不起作用;錯誤仍然出現。如何重命名該方法，我如何指示構建測試數據插件忽略此getter？

謝謝！
