我正在尝试为一个更新API编写一个Junit测试用例。该API正在使用JPA的saveAll方法来执行更新。该API工作正常，但是当尝试模拟saveAll方法时，它会给我以下错误：
io.mockk.MockKException:未找到以下项的答案：用户资料档案库（#1）.saveAll（用户详细信息..）

@Test
 fun testUpdateUserDetailsSuccess() {
   val userRepository = mockk<UserRepository>()

   every { userRepository.saveAll(anyList()) } returns getUserDetailsTestData();

   val userDetailsDatabaseAdapter = UserDetailsDatabaseAdapter(userRepository)
   val userResponse = userDetailsDatabaseAdapter.updateUserDetails(getUserDetails())
}

用户存储库

@Repository
interface UserRepository : JpaRepository<UserDetails, UUID> {
    fun findById(userId: UUID): List<UserDetails>
}

用户详细信息数据库适配器

override suspend fun updateUserDetails(userDetail: UserDetails): Either<CustomError, Int> =
            either {

//fetching some details from DB and then forming a list of userDetails

    val response = updateUserDetails(
                    userRepository,
                    userDetails
                ) andThen ::mapToCount
    response.bind()
    }

更新用户详细信息

fun updateUserDetails(
    userRepo: UserRepository,
    userDetails: List<UserDetails>
): Either<CustomError, List<UserDetails>> =
    bulkWriteToDatabase {
        userRepo.saveAll(userDetails)
    }
