Kotlin + Mockito +春季靴

我正在使用Spring Boot研究Kotlin,并且试图将Serenity用作报告。 但是我对Mockito遇到了一些问题,因为我无法模拟代码的最后一部分。

那是我的情况:

@RestController
@RequestMapping("/person")
class PersonController {

    @Autowired
    private lateinit var personUseCase : PersonUseCase


    @GetMapping("/all")
    fun findAllPeople(): DataModelResponse<List<PersonDataModelResponse>> {
        return DataModelResponse(
                PersonDataModelResponseMapper.transform(personUseCase.findAll()))
    }

}
@Component
class PersonUseCase {

    fun findAll(): List<PersonEntity> {
        val personImpl : Person = PersonImplementation()
        return personImpl.findAll()
    }
}
class PersonImplementation : Person {

    private val personDaoResponse :  PersonDaoResponse = PersonDaoResponse()

    override fun findAll(): List<PersonEntity> {

        val listPeopleDao = personDaoResponse.findAll()

        return PersonDaoMapper.transform(listPeopleDao)
    }

}
internal class PersonDaoResponse (
        val identification: Long = 0,
        val personName: String = "") {

    fun findAll(): List<PersonDaoResponse> {
        return listOf(PersonDaoResponse(1, "José"))
    }
}

我正在尝试在集成测试中模拟我的Dao:

@RunWith(SerenityRunner::class)
@WithTag("Integration")
@AutoConfigureMockMvc
@WebMvcTest
class PersonControllerTest {

    @InjectMocks
    private lateinit var personController : PersonController

    @InjectMocks
    private lateinit var personImplementation : PersonImplementation

    @SpyBean
    private lateinit var personUseCase : PersonUseCase

    @Spy
    private val personDaoResponse = PersonDaoResponse()

    @Autowired
    private lateinit var webApplicationContext: WebApplicationContext

    @Autowired
    private lateinit var mockMvc: MockMvc

    @Rule @JvmField
    var springMethodIntegration = SpringIntegrationMethodRule()

    @Before
    fun init() {
        MockitoAnnotations.initMocks(this)
        reset(personDaoResponse)

        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.webApplicationContext).build()
        this.mockMvc = MockMvcBuilders.standaloneSetup(personController).setMessageConverters(MappingJackson2HttpMessageConverter()).build()
    }

    @Test
    fun `integration success`() {
        doReturn(listOf(PersonDaoResponse(999L, "Zé")))
                .`when`(this.personDaoResponse).findAll()
        val result = this.personController.findAllPeople()
        assertNotNull(result)
        assertEquals(999L, result.data[0].personId)
        assertEquals("Zé", result.data[0].name)
    }

}

如果执行某些操作,我知道此模拟程序有效,我尝试调用模拟方法: assertEquals(999L,this.personDaoResponse.findAll()[0] .identification)

如何在这种集成测试中模拟此Dao?

答案 0 :(得分:1)

不幸的是,我对Mockito问题没有答案,因为我离开Mockito已有很长时间了。

如果不是必须使用Mockito,我建议从Spring Boot + Kotlin经验中使用MockK(https://github.com/mockk/mockk)。如果还需要可注射的模拟Bean,则还可以添加SpringMockK(https://github.com/Ninja-Squad/springmockk)。

由于您的“ PersonDaoResponse”是在PersonImplementation类中构造的,因此可以在MockK中使用类似的方法:

every { anyConstructed<PersonDaoResponse>().findAll() } returns listOf(PersonDaoResponse(999L, "Zé"))
