如何使用livedata对coruotine进行单元测试

implementation "androidx.lifecycle:lifecycle-livedata-ktx:2.4.0"
testImplementation "androidx.arch.core:core-testing:2.1.0"

val testCoroutineScope = TestCoroutineScope()

@Test
fun testCoroutineWithLiveData() = testCoroutineScope.runBlockingTest {
    // 在这里编写测试代码
}

val liveData = MutableLiveData<String>()
val observer = Observer<String> { value ->
    // 在这里处理 LiveData 的数据变化
}
liveData.observeForever(observer)

liveData.value = "Test Value"
testCoroutineScope.advanceTimeBy(1000) // 模拟时间流逝

assertEquals("Test Value", liveData.value)
