不能用 mockk 模拟 com.github.kittinunf.fuel.Fuel

Question

我在以下问题上需要您的帮助：我无法在 Fuel.get 调用中被嘲笑。 我试过的：

这是调用 Fuel 的服务类。

class JiraService {
    private val logger: Logger = LoggerFactory.getLogger(JiraService::class.java)

    fun checkIfUsersExistInJira(usernames: List<String>, jiraConfig: Configuration): Boolean {
        var checkResultOk = true;
        val encodedCredentials =

        usernames.forEach {
            Fuel.get("${jiraConfig[url]}/rest/api/2/groupuserpicker?query=${it}&maxResults=1")
                .appendHeader("Authorization", "Basic ...")
                .appendHeader("Content-Type", "application/json")
                .responseObject(UserInfoDeserializer)
                .third
                .fold(
                    failure = { throwable ->
                        logger.error(
                            "Can't check users in jira for user $it",
                            throwable
                        )
                    },
                    success = { userExists ->
                        checkResultOk = checkResultOk && userExists
                    }
                )
        }
        return checkResultOk
    }
}

测试：

@ExtendWith(MockKExtension::class)
class JiraServiceTest {

    private val jiraConfig = createJiraConf()
    private val fuelRequest = mockk<Request>()
    private val fuelResponse = mockk<Response>()
    private val fuelMock = mockk<Fuel>()

    @BeforeEach
    fun setUp() {
        mockkStatic(FuelManager::class)
        every {
            fuelMock.get(eq("${jiraConfig[url]}/rest/api/2/groupuserpicker?query=user_1@test.com&maxResults=1"))
                .appendHeader(eq("Authorization"), any())
                .appendHeader(eq("Content-Type"), eq("application/json"))
                .responseObject(UserInfoDeserializer)
        } returns ResponseResultOf(first = fuelRequest, second = fuelResponse, third = Result.success(false))
    }

    @Test
    fun `will return FALSE for user not existing in jira`() {
        // given
        val usernames = listOf("user_1@test.com", "user_3@test.com", "user_4@test.com")

        // when
        JiraService().checkIfUsersExistInJira(usernames, jiraConfig)

        // then
    }
}

而且我总是看到错误：

Caused by: some.url.net
    com.github.kittinunf.fuel.core.FuelError$Companion.wrap(FuelError.kt:86)
    com.github.kittinunf.fuel.toolbox.HttpClient.executeRequest(HttpClient.kt:39)
Caused by: java.net.UnknownHostException: some.url.net
...

所以它总是在忽略 fueMock 的情况下进行真正的 Fuel 调用。 我做错了什么？

感谢您的帮助！

如果有人需要，可以进行以下测试：

@ExtendWith(MockKExtension::class)

类 JiraServiceTest {

private val jiraConfig = createJiraConf()
private val fuelRequest1 = mockk<DefaultRequest>()
private val fuelRequest3 = mockk<DefaultRequest>()
private val fuelRequest4 = mockk<DefaultRequest>()
private val fuelResponse = mockk<Response>()

@BeforeEach
fun setUp() {
    mockkObject(Fuel)
    every {
        Fuel.get(eq("${jiraConfig[url]}/rest/api/2/groupuserpicker?query=user_1@test.com&maxResults=1"))
    } returns fuelRequest1
    every {
        Fuel.get(eq("${jiraConfig[url]}/rest/api/2/groupuserpicker?query=user_3@test.com&maxResults=1"))
    } returns fuelRequest3
    every {
        Fuel.get(eq("${jiraConfig[url]}/rest/api/2/groupuserpicker?query=user_4@test.com&maxResults=1"))
    } returns fuelRequest4

    every { fuelRequest1.appendHeader(any<String>(), any()) } returns fuelRequest1
    every { fuelRequest3.appendHeader(any<String>(), any()) } returns fuelRequest3
    every { fuelRequest4.appendHeader(any<String>(), any()) } returns fuelRequest4

    every { fuelRequest1.responseObject(UserInfoDeserializer) } returns ResponseResultOf(
        first = fuelRequest1,
        second = fuelResponse,
        third = Result.success(false)
    )
    every { fuelRequest3.responseObject(UserInfoDeserializer) } returns ResponseResultOf(
        first = fuelRequest3,
        second = fuelResponse,
        third = Result.success(true)
    )
    every { fuelRequest4.responseObject(UserInfoDeserializer) } returns ResponseResultOf(
        first = fuelRequest4,
        second = fuelResponse,
        third = Result.success(true)
    )
}

@Test
fun `will return FALSE for user not existing in jira`() {
    // given
    val usernames = listOf("user_1@test.com", "user_3@test.com", "user_4@test.com")

    // when
    val result = JiraService().checkIfUsersExistInJira(usernames, jiraConfig)

    // then
    assertThat(result, equalTo(false))
}

@Test
fun `will return TRUE for users existing in jira`() {
    // given
    val usernames = listOf("user_3@test.com", "user_4@test.com")

    // when
    val result = JiraService().checkIfUsersExistInJira(usernames, jiraConfig)

    // then
    assertThat(result, equalTo(true))
}

}
