/**
 * We extend ActivityInstrumentationTestCase2 in order to have access to methods like getActivity
 * and getInstrumentation. Depending on what methods we are going to need, we can put our
 * step definitions inside classes extending any of the following Android test classes:
 * <p/>
 * ActivityInstrumentationTestCase2
 * InstrumentationTestCase
 * AndroidTestCase
 * <p/>
 * The CucumberOptions annotation is mandatory for exactly one of the classes in the test project.
 * Only the first annotated class that is found will be used, others are ignored. If no class is
 * annotated, an exception is thrown.
 * <p/>
 * The options need to at least specify features = "features". The default value that is set by
 * Cucumber internally does not work because features are not on the classpath under Android.
 * Features must be placed inside assets/features/ of the test project (or a subdirectory thereof).
