/**
 * Created by mhwang on 9/25/17.
 *
 * This test covers the gap in DcaeServicesApiServiceImplTests - testing the GET query interface
 * The approach taken here is standing up an H2 in-memory database which is different from the
 * original test which made an attempt to mock the database calls but ran into an impasse. The
 * test here was not included in the original class because of conflicting setup operations.
