Espresso测试失败由于应用程序而不是空闲的例外:以下空闲条件失败async_tasks_have_idled

Question

我的浓缩咖啡测试与浓缩咖啡版本2.2.2一起工作正常，但是当我将工作室更新为最新的工作室，并且应用迁移规则测试将失败并需要更新版本。

库使用

androidTestImplementation'com.android.support.test.espresso:espresso-core:3.0.1'
    implementation 'com.android.support.test.espresso:espresso-idling-resource:3.0.1'
    androidTestImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestCompile 'com.android.support.test:rules:1.0.1'
    androidTestImplementation "com.android.support:support-annotations:${support}"
    implementation fileTree(include: ['*.jar'], dir: 'libs')

对于测试过程中的空闲资源，我正在使用iDlingResources样本，我还尝试使用 IntentService和 BroadcastReceiver时尝试使用空闲资源 - 库。
由于 Espresso咖啡中存在问题。浓缩咖啡iDlingresourceregistry.sync已经报告，并将在下一个版本中进行修复。我使用IdlingRegistry进行注册。但是我仍然得到AppNotIdleException
日志CAT

在此Google组线程上找到了解决方案

我有一个正在逐渐消失的进度栏，但没有设置GONE的可见性，因此它不断更新UI。因此，该应用程序从未闲置，尽管进行了背景工作，并且空闲资源设置为免费。
