kotlin 中的单元测试规范

Question

我需要获得符合规范的查询结果。为此，我使用了 JpaSpecificationExecutor 的 List<T> findAll(@Nullable Specification<T> spec) 方法。问题是我不能在测试中做同样的事情，因为它有几个参数相同的方法。这是我的方法：

fun getFaqList(category: FaqCategory?, subcategory: FaqCategory?, searchText: String?): List<FaqEntity> {

    val spec = Specification.where(FaqSpecification.categoryEquals(category))
        ?.and(FaqSpecification.subcategoryEquals(subcategory))
        ?.and(
            stringFieldContains("title", searchText)
                ?.or(stringFieldContains("description", searchText))
        )

    return faqRepository.findAll(spec)
}

我正在尝试的测试运行:

@MockK
private lateinit var faqRepository: FaqRepository

@InjectMockKs
private lateinit var faqService: FaqService

companion object {
    val FAQ_CATEGORY_ENTITY = FaqCategoryEntity(
        id = AGRICULTURE
    )

    val FAQ_SUBCATEGORY_ENTITY = FaqCategoryEntity(
        id = AGRICULTURE_GENERAL
    )

    val FAQ_ENTITY = FaqEntity(
        id = FAQ_ID,
        title = "title",
        description = "description",
        category = FAQ_CATEGORY_ENTITY,
        subcategory = FAQ_SUBCATEGORY_ENTITY
    )
}

@Test
fun `getFaqList - should return faq list`() {
    val faqList = listOf(FAQ_ENTITY)

    every { faqRepository.findAll(any()) } returns faqList

    val response = faqService.getFaqList(AGRICULTURE, AGRICULTURE_GENERAL, FAQ_SEARCH_TEXT)

    assertThat(response).isEqualTo(faqList)
}

我遇到错误：

Overload resolution ambiguity. All these functions match.
public abstract fun <S : FaqEntity!> findAll(example: Example<TypeVariable(S)!>): 
(Mutable)List<TypeVariable(S)!> defined in kz.btsd.backkotlin.faq.FaqRepository
public abstract fun findAll(pageable: Pageable): Page<FaqEntity!> defined in 
kz.btsd.backkotlin.faq.FaqRepository
public abstract fun findAll(sort: Sort): (Mutable)List<FaqEntity!> defined in 
kz.btsd.backkotlin.faq.FaqRepository
public abstract fun findAll(spec: Specification<FaqEntity!>?): (Mutable)List<FaqEntity!> 
defined in kz.btsd.backkotlin.faq.FaqRepository

为了 spring 理解，我应该在 findAll() 参数中写什么：

faqRepository.findAll(any())

Answer 1

问题是编译器无法决定 any() 应该是什么类型，因此无法决定选择哪种方法。

我不确定 any() 的来源，但如果它来自某个模拟库，您可能可以使用 any(Specification)。否则，您可以将 any() 的签名更改为 return a Specification 或将其转换为 Specification.

Answer 2

解决了

的问题

every { faqRepository.findAll(any<Specification<FaqEntity>>()) } returns faqList
