由于IdlingResource并不总是变得闲置，我们有一个不稳定的测试：
androidx.test.espresso.IdlingResourceTimeoutException: Wait for [MyCustomIdldingResource:2131231404:com.example:id/message] to become idle timed out
at dalvik.system.VMStack.getThreadStackTrace(Native Method)
at java.lang.Thread.getStackTrace(Thread.java:1536)
at androidx.test.espresso.base.DefaultFailureHandler.getUserFriendlyError(DefaultFailureHandler.java:96)

有什么方法可以让我挂接到IdlingRegistry或IdlingResource以在引发异常之前立即执行一些代码？我想在应用程序最终超时之前监视它的状态。
