Purpose

Documentation fix

The docs are explaining how to use a FakeRequest here, but the example omits that. Here is the original:

You can also retrieve an action reference from the reverse router and invoke it. This also allows you to use FakeRequest which is a mock for request data:

@Test
public void testCallIndex() {
  Result result = route(
    controllers.routes.HomeController.index(),
  );
  assertEquals(OK, result.status());
}
