/**
 * <p>
 * Base class for {@link ClinicService} integration tests.
 * </p>
 * <p>
 * &quot;AbstractClinicTests-context.xml&quot; declares a common
 * {@link javax.sql.DataSource DataSource}. Subclasses should specify
 * additional context locations which declare a
 * {@link org.springframework.transaction.PlatformTransactionManager PlatformTransactionManager}
 * and a concrete implementation of {@link ClinicService}.
 * </p>
 * <p>
 * This class extends {@link AbstractTransactionalJUnit4SpringContextTests},
 * one of the valuable testing support classes provided by the
 * <em>Spring TestContext Framework</em> found in the
 * <code>org.springframework.test.context</code> package. The
 * annotation-driven configuration used here represents best practice for
 * integration tests with Spring. Note, however, that
 * AbstractTransactionalJUnit4SpringContextTests serves only as a convenience
 * for extension. For example, if you do not wish for your test classes to be
 * tied to a Spring-specific class hierarchy, you may configure your tests with
 * annotations such as {@link ContextConfiguration @ContextConfiguration},
 * {@link org.springframework.test.context.TestExecutionListeners @TestExecutionListeners},
 * {@link org.springframework.transaction.annotation.Transactional @Transactional},
 * etc.
 * </p>
 * <p>
 * AbstractClinicTests and its 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>petRepository</code> instance
 * variable, which uses autowiring <em>by type</em>. As an alternative, we
 * could annotate <code>petRepository</code> with
 * {@link javax.annotation.Resource @Resource} to achieve dependency injection
 * <em>by name</em>.
 * <em>(see: {@link ContextConfiguration @ContextConfiguration},
 * {@link org.springframework.test.context.support.DependencyInjectionTestExecutionListener DependencyInjectionTestExecutionListener})</em></li>
 * <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.
 * <em>(see: {@link org.springframework.test.context.transaction.TransactionConfiguration @TransactionConfiguration},
 * {@link org.springframework.transaction.annotation.Transactional @Transactional},
 * {@link org.springframework.test.context.transaction.TransactionalTestExecutionListener TransactionalTestExecutionListener})</em></li>
 * <li><strong>Useful inherited protected fields</strong>, such as a
 * {@link org.springframework.jdbc.core.simple.SimpleJdbcTemplate SimpleJdbcTemplate}
 * that can be used to verify database state after test operations or to verify
 * the results of queries performed by application code. An
 * {@link org.springframework.context.ApplicationContext ApplicationContext} is
 * also inherited and can be used for explicit bean lookup if necessary.
 * <em>(see: {@link org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests AbstractJUnit4SpringContextTests},
 * {@link AbstractTransactionalJUnit4SpringContextTests})</em></li>
 * </ul>
 * <p>
 * The Spring TestContext Framework and related unit and integration testing
 * support classes are shipped in <code>spring-test.jar</code>.
