// Since the reflection interface for DynamicMessage is implemented by
// GenericMessageReflection, the only thing we really have to test is
// that DynamicMessage correctly sets up the information that
// GenericMessageReflection needs to use. So, we focus on that in this
// test. Other tests, such as generic_message_reflection_unittest and
// reflection_ops_unittest, cover the rest of the functionality used by
// DynamicMessage.
