grails - 当 PostConstruct 调用注入(inject)服务时 Spock 失败

Question

谁能告诉我如何解决在模拟之前调用 PostConstruct 的问题:

服务:

class MyService {
    SecondService secondService // injected

    @PostConstruct
    void init() {
        myFunction()
    }

    void myFunction() {
        secondService.doSomething()
    }

}

测试:

@TestFor(MyService)
class MyServiceSpec extends Specification {
   void "testing my service"() {
      given:
         MyService service = GroovySpy(MyService) {
             myFunction() >> null
         }
      then:
         true
   }
}

给出以下错误:

Invocation of init method failed; nested exception is java.lang.NullPointerException: Cannot invoke method doSomething() on null object

如果您有 @TestFor(MyService) - MyService 实例将自动创建，您可以将其用作“服务”。而且您不需要手动创建 MyService。

所以你只能删除 @TestFor(MyService) 或者使用它并删除 MyService 服务。

但是您还需要正确模拟“secondService”

@FreshRuntime
@TestFor(MyService)
class MyServiceSpec extends Specification {

    def secondService = GroovyMock(SecondService)

    def doWithSpring = {
        secondService(InstanceFactoryBean, secondService, SecondService)
    }

    void "testing my service"() {
        when:
        service.myFunction()
        then:
        1 * secondService.doSomething()
    }
}
