[英]Unit tests in kotlin with specifications
我需要獲取帶有規范的查詢結果。 為此,我使用了 JpaSpecificationExecutor 的List<T> findAll(@Nullable Specification<T> spec)
方法。 問題是我不能在測試中做同樣的事情,因為它有幾個具有相同參數的方法。 這是我的方法:
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)
}
以及我正在嘗試運行的測試:
@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)
}
我收到錯誤:
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
為了讓 spring 理解,我應該在 findAll() 參數中寫什么:
faqRepository.findAll(any())
解決了這個問題
every { faqRepository.findAll(any<Specification<FaqEntity>>()) } returns faqList
問題是編譯器無法決定any()
應該是什么類型,因此無法決定選擇哪種方法。
我不確定any()
來自哪里,但如果它來自某些 mocking 庫,您可能可以使用any(Specification)
。 否則,您可能能夠更改any()
的簽名以返回Specification
或將其強制轉換為Specification
。
