735<h2>Class Overview</h2>
736<p itemprop="articleBody">Represents a resource of an application under test which can cause asynchronous background work
737 to happen during test execution (e.g. an intent service that processes a button click). By
738 default, <code><a href="../../../../../reference/android/support/test/espresso/Espresso.html">Espresso</a></code> synchronizes all view operations with the UI thread as well as
739 AsyncTasks; however, it has no way of doing so with "hand-made" resources. In such cases, test
740 authors can register the custom resource and <code><a href="../../../../../reference/android/support/test/espresso/Espresso.html">Espresso</a></code> will wait for the resource to
741 become idle prior to executing a view operation.
742 <br><br>
743 <b>Important Note:</b> it is assumed that the resource stays idle most of the time.
