defer() 我正在研究 RxKotlin，出现了一个问题：和 之间有什么区别defer{}

我已在->模块中导入mockk库。测试类中没有导入错误，但是当我运行测试时，我收到如下错误：commonTestshared

Unresolved reference: every
Unresolved reference: mockk
Unresolved reference: verify

在我使用mock库方法的所有地方。错误的原因可能是什么？

我的测试示例在控制台中出现错误：

class DefaultAppPreferenceStorageTest {

    val appPreference = mockk<AppPreference>() //Unresolved reference: mockk
    val jsonService = mockk<JsonService>() //Unresolved reference: mockk

    val jsonKey = "key"
    val value = 1
    val stringValue = "$value"
    val defaultIntValue = Random.nextInt()

    val storage = DefaultAppPreferenceStorage(
        appPreference,
        jsonService
    )

    inner class PutJsonTest {

        @BeforeTest
        fun beforeEachTest() {
            every { jsonService.mapToString(value) } returns stringValue //Unresolved reference: every

            storage.putJson(jsonKey, value)
        }

        @Test
        fun …

我需要在 TextView 中显示百分比值，例如“15 %”，我通过这种方式在 viewModel 中执行此操作，并且它有效：

                    perfusionIndexValue.postValue(
                        list.lastOrNull()?.perfusionIndex?.takeIf {
                            it != PerfusionIndex.NO_DATA
                        }?.value?.toString().orEmpty() + " %"
                    )

但如果我用资源来做：

                    perfusionIndexValue.postValue(
                        list.lastOrNull()?.perfusionIndex?.takeIf {
                            it != PerfusionIndex.NO_DATA
                        }?.value?.toString().orEmpty() + Resources.getSystem().getString(R.string.pi_percent)
                    )

我明白了

io.reactivex.rxjava3.exceptions.UndeliverableException: The exception could not be delivered to the consumer because it has already canceled/disposed the flow or the exception has nowhere to go to begin with.

我如何设置像“15%”这样的文本
