/**
 * This rule makes it easy to use Espresso-Intents APIs in functional UI tests. This class is an
 * extension of {@link ActivityTestRule}, which initializes Espresso-Intents before each test
 * annotated with <a href="http://junit.org/javadoc/latest/org/junit/Test.html"><code>Test</code>
 * </a> and releases Espresso-Intents after each test run. The Activity will be terminated after
 * each test and this rule can be used in the same way as {@link ActivityTestRule}.
 *
 * <p>Espresso-Intents APIs can be used in two ways:
 *
 * <ul>
 *   <li>Intent Verification, using the {@link Intents#intended(Matcher)} API
 *   <li>Intent Stubbing, using the {@link Intents#intending(Matcher)} API
 * </ul>
 *
 * @param <T> The activity to test
 * @deprecated Use {@link androidx.test.espresso.intent.Intents.init()}, in conjunction with {@link
 *     androidx.test.core.app.ActivityScenario} or {@link
 *     androidx.test.ext.junit.rules.ActivityScenarioRule} instead.
