/**
* 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
