* Abstract {@link Transactional transactional} extension of

* <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}.
