The Crux

通过Build Test Data插件调用MyDomainObject.build（）时，我的单元测试中出现以下错误：

例外

            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]

根据堆栈跟踪，这发生在buildtestdata插件代码中。当我的类PesticideApplicator被添加到PesticideProfile类时，它似乎是null。

传递给PesticideProfile时，我要求构建的类是如何才能为null？

源代码

测试用例

            @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
            }

            }

感谢您的帮助！

问题是由构建测试数据插件尝试在PesticideApplicator中设置用户的值引起的。问题是getUser（）不是一个字段，它只是一个实用程序帮助程序：

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

从getUser()删除PesticideApplicator解决了问题。

那就是说，我仍然想要一个帮助方法来访问用户（最好不要让我的代码知道另一个类的内部）。标记方法@Transient不起作用;错误仍然出现。如果没有重命名方法，我怎样才能指示构建测试数据插件忽略这个getter？

谢谢！
