通过mockContstructor验证深层模拟失败

Question

在测试中，我想验证当调用该模型的方法时，该模型是否会调用客户端。 被测类-模型类-是对象单例。 （KubernetesResourceModel.kt）

object KubernetesResourceModel {
…
    private fun createClient(): NamespacedKubernetesClient {
        return DefaultKubernetesClient(ConfigBuilder().build())
    }

对客户端的实际调用-DefaultKubernetesClient-发生在KubernetesResourceModel（Cluster.kt）内的实例变量中

class Cluster(val client: NamespacedKubernetesClient) {
...
    private fun loadAllNameSpaces(): Sequence<Namespace> {
        return  client.namespaces().list().items.asSequence()
    }

在测试中，我对客户端进行了存根处理，然后验证了在调用KubernetesResourceModel.getAllNamespaces（KubernetesResourceModelTest.kt）时是否执行了对客户端库的调用：

    @Test
    fun `should call list namespaces on client`() {
        // given
        mockClient(emptyList())
        // when
        KubernetesResourceModel.getAllNamespaces()
        // then
        verify { anyConstructed<DefaultKubernetesClient>().namespaces().list().items }
    }
...
    private fun mockClient(namespaces: List<Namespace>) {
        // client.namespaces().list().items.asSequence()
        mockkConstructor(DefaultKubernetesClient::class)
        every { anyConstructed<DefaultKubernetesClient>().namespaces() } returns
                spyk {
                    every { list() } returns
                            spyk {
                                every { items } returns
                                        namespaces
                            }
                    every { watch(any()) } returns
                            mockk()
                }

模拟工作正常，我看到KubernetesResourceModel.getAllNamespaces()返回了我在进行模拟时传递的空列表（mockClient(emptyList())）。 不幸的是，验证

verify { anyConstructed<DefaultKubernetesClient>().namespaces().list().items }（KubernetesResourceModelTest.kt）

告诉我没有发生client.namespaces().list()的通话：

知道我缺少什么吗？
