kotlin 中的单元测试与规范

[英]Unit tests in kotlin with specifications

我需要获取带有规范的查询结果。 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,因为它有几个具有相同参数的方法。 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)
}

以及我正在尝试运行的测试:

@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)
}

我收到错误:

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

为了让 spring 理解,我应该在 findAll() 参数中写什么:

faqRepository.findAll(any())

解决了这个问题

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

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()来自哪里,但如果它来自某些 mocking 库,您可能可以使用any(Specification) 否则,您可能能够更改any()的签名以返回Specification或将其强制转换为Specification
