Kotlin - Mockito 测试失败

Question

我的 kotlin 代码库中有以下方法

package com.service.organization

import com.domain.Organization
import com.repository.organization.OrganizationRepository
import org.springframework.data.domain.Page
import org.springframework.data.domain.Pageable
import org.springframework.stereotype.Service
import org.springframework.transaction.annotation.Transactional

interface OrganizationService {
    fun listAll(pageable : Pageable , archived : Boolean?) : Page<Organization>
}

@Service
internal class OrganizationServiceImpl(private val organizationRepository : OrganizationRepository) : OrganizationService {

    @Transactional(readOnly = true)
    override fun listAll(pageable : Pageable , archived : Boolean?) : Page<Organization> {
        val organizations : Page<Organization>
        if (archived !== null) {
            organizations = organizationRepository.findByArchived(archived , pageable)
        } else {
            organizations = organizationRepository.findAll(pageable)
        }
        return organizations
    }
}

我有以下测试来测试存档的流程

package com.service.organization

import com.domain.Organization
import org.junit.Assert.assertNotNull
import org.junit.Assert.assertTrue
import org.junit.Before
import org.junit.Test
import org.junit.runner.RunWith
import org.mockito.Mock
import org.mockito.Mockito
import org.mockito.junit.MockitoJUnitRunner
import org.springframework.data.domain.PageImpl
import org.springframework.data.domain.Pageable
import java.util.*

@RunWith(MockitoJUnitRunner::class)
class OrganizationServiceTest {

    @Mock
    lateinit var mockOrganizationRepository: OrganizationRepository

    @Mock
    lateinit var mockPageable: Pageable

    internal lateinit var organizationServiceImpl: OrganizationServiceImpl

    @Before
    fun setUp() {
        organizationServiceImpl = OrganizationServiceImpl(mockOrganizationRepository)
        //mockPageable = Mockito.mock(Pageable::class.java)
    }

    @Test
    fun testListAll_Archived_NoOrgsReturned() {
        val archived = true
        var mockPageableObj = Mockito.mock(Pageable::class.java)
        val organizationList = LinkedList<Organization>()
        val returnedPage = PageImpl(organizationList)

        var exc: Exception? = null
        try {
            Mockito.`when`(mockOrganizationRepository.findByArchived(Mockito.anyBoolean(), Mockito.isA(Pageable::class.java))).thenReturn(returnedPage)

            val organizationPage = organizationServiceImpl.listAll(mockPageableObj, archived)
            assertNotNull(organizationPage)
            assertTrue(organizationPage.size == returnedPage.size)

            Mockito.verify(mockOrganizationRepository, Mockito.times(1)).findByArchived(Mockito.anyBoolean(), Mockito.isA(Pageable::class.java))
        } catch(e: Exception) {
            exc = e
            exc.printStackTrace()
        }
        assertNotNull(exc)
    }

}

但是，当我运行该测试时 - 我收到以下错误

有谁知道我在这里做错了什么？

提前致谢

我没有使用匹配器，而是使用了方法调用的特定值。

更新

这篇中等文章还强调了一个有效的解决方案，您可以在其中传递 any() 匹配器https://medium.com/@elye.project/befriending-kotlin-and-mockito-1c2e7b0ef791
