/**
 * <p>
 * Abstract {@link Transactional transactional} extension of
 * {@link AbstractJUnit38SpringContextTests} which adds convenience
 * functionality for JDBC access. Expects a {@link javax.sql.DataSource} bean
 * and a {@link PlatformTransactionManager} bean to be defined in the Spring
 * {@link ApplicationContext application context}.
 * </p>
 * <p>
 * This class exposes a {@link SimpleJdbcTemplate} and provides an easy way to
 * {@link #countRowsInTable(String) count the number of rows in a table} ,
 * {@link #deleteFromTables(String...) delete from the database} , and
 * {@link #executeSqlScript(String, boolean) execute SQL scripts} within a
 * transaction.
 * </p>
 * <p>
 * Concrete subclasses must fulfill the same requirements outlined in
 * {@link AbstractJUnit38SpringContextTests}.
