Espresso - 如何在没有断言/查看交互的情况下等待空闲？

Question

我想简单地阻塞检测（测试）线程，直到 Espresso 空闲。

fun test(){
    // do some stuff
    Espresso.waitForIdle()
    // do some more stuff once Espresso reports that the application is idle
}

做到这一点的最佳方法是什么？

注：Espresso.waitForIdle()是我编的方法

Answer 1

您可以使用InstrumentationRegistry.getInstrumentation().waitForIdleSync(). https://developer.android.com/reference/android/app/Instrumentation.html#waitForIdleSync()

还有Espresso.onIdle()，但文档警告Only call this method for tests that do not interact with any UI elements, but require Espresso's main thread synchronisation! https://developer.android.com/reference/android/support/test/espresso/Espresso.html#onIdle()
