Testing Spring Data JPA repositories

Testing is an important part of software engineering and with Spring Boot 2.0 @DataJpaTest is introduced to ease the testing of JPA repositories. This annotation will use an embedded database for testing and will auto-configure TestEntityManager to verify the JPA Repository operations.

The following is the test for CommentRepository:

@RunWith(SpringRunner.class)@DataJpaTestpublic class CommentRepoTest {    @Autowired    private TestEntityManager testEntityManager;    @Autowired    private CommentRepository commentRepository;    @Test    public void     findByCreatedYearAndMonthAndDay_HappyPath_ShouldReturn1Comment() {        // Given        Comment comment = new Comment();        comment.setComment("Test");        comment.setType(CommentType.PLUS);
