我正在尝试执行单元测试和模拟改型调用，但没有成功。当我运行测试时，我只打印了end。我还应该打印onResponse（）。
当我运行我的应用程序时，代码工作正常，只是测试没有调用模拟的API调用。

视图模型中的方法：

fun loadSensors() {
    CoroutineScope(Dispatchers.IO).launch {
        sensorsService.getUserSensors(getUserToken(), getUserId())
            .enqueue(object : Callback<List<Long>> {
                override fun onResponse(
                    call: Call<List<Long>>,
                    response: Response<List<Long>>
                ) {
                    println("onResponse()")
                }

                override fun onFailure(call: Call<List<Long>>, t: Throwable) {
                    println("onFailure()")
                }
            })
    }
    println("end")
}

接口：

@GET("/sensors")
fun getUserSensors(): Call<List<Long>>

应用模块：

@Provides
@Singleton
fun provideRetrofitFactory(gsonConverterFactory: GsonConverterFactory): Retrofit {
    val client = OkHttpClient.Builder().build()

    return Retrofit.Builder()
        .baseUrl("http://<url>")
        .addConverterFactory(gsonConverterFactory)
        .client(client)
        .build()
}

测试：

@OptIn(DelicateCoroutinesApi::class)
private val mainThreadSurrogate = newSingleThreadContext("UI thread")

@OptIn(ExperimentalCoroutinesApi::class)
@BeforeAll
fun beforeAll() {
    Dispatchers.setMain(mainThreadSurrogate)
}

@Test
fun loadSensors() {
    val mockedCall = mockk<retrofit2.Call<List<Long>>>()
    every { mockedCall.enqueue(any()) } answers {
        val callback = args[0] as retrofit2.Callback<List<Long>>
        val response = retrofit2.Response.success(200, listOf(1L, 2L, 3L))

        callback.onResponse(mockedCall, response)
    }

    every { sensorsService.getUserSensors(any(), any()) } answers {
        mockedCall
    }
}
