使用 Spock 进行测试时，Grails 无法将服务注入(inject)域

Question

使用 Spock 进行 grails 单元测试时，无法自动将服务实例注入(inject)域。

下面是我的代码。

服务:

class HiService {

    public HiService(){
        println "Init HiService," + this.toString()
    }

    def sayHi(String name){
        println "Hi, ${name}"
    }
}

领域:

class User {

    public User(){
        if (hiService == null){
            println "hiService is null when new User(${name})"
        }
    }

    String name

    def hiService

    def sayHi(){
        println "Before use hiService " + hiService?.toString()
        hiService.sayHi(name)
        println "End use hiService" +  hiService?.toString()
    }
}

测试用例:

@TestFor(HiService)
@Mock([User])
class HiServiceTest extends Specification {

    def "test sayHi"() {

        given:
        def item = new User( name: "kitty").save(validate: false)

        when: "Use service method"
        item.sayHi()

        then : "expect something happen"
        assertEquals(1, 1)
    }
}

以下是控制台日志:

--Output from test sayHi--
Init HiService,test.HiService@530f5e8e
hiService is null when new User(null)
Before use hiService null
| Failure:  test sayHi(test.HiServiceTest)
|  java.lang.NullPointerException: Cannot invoke method sayHi() on null object
	at test.User.sayHi(User.groovy:17)
	at test.HiServiceTest.test sayHi(HiServiceTest.groovy:20)

服务已初始化，但无法注入(inject)域。但是当直接运行应用程序时，服务会自动注入(inject)到域中

如果您不想 Autowiring ，则需要进行集成测试。如果使用 Grails 3，则使用 @Integration 进行注释，如果使用 grails 2，则扩展 IntegrationSpec。
