/**
 * Integration test of the Service and the Repository layer.
 * <p>
 * ClinicServiceSpringDataJpaTests subclasses benefit from the following services provided by the Spring
 * TestContext Framework: </p> <ul> <li><strong>Spring IoC container caching</strong> which spares us unnecessary set up
 * time between test execution.</li> <li><strong>Dependency Injection</strong> of test fixture instances, meaning that
 * we don't need to perform application context lookups. See the use of {@link Autowired @Autowired} on the <code>{@link
 * ClinicServiceTests#clinicService clinicService}</code> instance variable, which uses autowiring <em>by
 * type</em>. <li><strong>Transaction management</strong>, meaning each test method is executed in its own transaction,
 * which is automatically rolled back by default. Thus, even if tests insert or otherwise change database state, there
 * is no need for a teardown or cleanup script. <li> An {@link org.springframework.context.ApplicationContext
 * ApplicationContext} is also inherited and can be used for explicit bean lookup if necessary. </li> </ul>
