/**
 * Annotation to assign a small test size qualifier to a test. This annotation can be used at the
 * method or class level.
 *
 * <p>Test size qualifiers are a great way to structure test code and are used to assign a test to a
 * suite of tests that have similar run times.
 *
 * <p>Execution time: &lt;200ms
 *
 * <p>Small tests should be run very frequently, focused on units of code to verify specific logical
 * conditions. Tests should run in an isolated environment and use fake objects for external
 * dependencies. Resource access (for example, to the file system, network, or databases) is not
 * permitted. Tests that interact with hardware, make binder calls, or facilitate android
 * instrumentation should not use this annotation.
 *
 * <p><b>Note:</b> This class replaces the deprecated Android platform size qualifier <a
 * href="{@docRoot}reference/android/test/suitebuilder/annotation/SmallTest.html"><code>
 * android.test.suitebuilder.annotation.SmallTest</code></a> and is the recommended way to annotate
 * tests written with the AndroidX Test libraries.
