Question

以下是域名：

package com.test
class Person{
    String name
    static mappedBy= [friends:'none']
    static hasMany=[friends:Person]
}

它适用于正常情况，但是当我尝试通过在spock中使用@Mock注释进行模拟来进行测试来保存时，得到以下异常：

|  org.grails.datastore.mapping.model.IllegalMappingException:

     Non-existent mapping property [none] specified for property [friends] in class [com.test.Person]

以下是测试用例：

import grails.test.mixin.Mock
import grails.test.mixin.TestFor
import spock.lang.Specification

@TestFor(PersonController)
@Mock([Person])
class PersonControllerSpec extends Specification{

    def "test save person"(){
        given:"some person request parameters set for person"
        params.putAll([name:'test234', friends:[], action:'save', controller:'person'])

        when:"perosn.save is called"
        controller.save()

        then:"it must create person object"
        Person.count() == 1
      }

}

知道在这种情况下可以做些什么吗？

此问题在grails 2.5.1之后修复：https://github.com/grails/grails-core/issues/669

我通过升级到Grails 2.5.5解决了我们项目中的问题，并将使用过的hibernate4插件更新为版本hibernate4：5.0.0.RELEASE。

Answer 2

虽然已存在针对同一问题的Jira jira.grails.org/browse/GRAILS-11285

我能够通过更改grails-datastore jar的版本来找到解决方法，因为我们在下面得到了例外

   Non-existent mapping property [none] specified for property [friends]

在GormMappingConfigurationStrategy.java中，它位于grails-datastore-core jar下。

因此，在将版本从3.0.6升级到3.1.5后，为了安全起见，添加了对测试环境的检查，如下所示

        if (Environment.getCurrentEnvironment() == Environment.TEST) {

            compile 'org.grails:grails-datastore-core:3.1.5.RELEASE'
        }

现在，jar只会添加到测试环境中，我们可以继续测试用例。

干杯!!!

运行测试用例时为属性指定的不存在的映射属性[none]
