/**
 *  Main test class, containing several JDBC and script based tests to
 *  verify correct operation of the engine.<p>
 *
 *  The tests consist of the following:
 * <ul>
 * <li>
 *  Built-in tests for operations, especially those relating to JDBC.
 *</li>
 * <li>
 *  Speed tests using insert / delete / update on a simple table.<p>
 *</li>
 * <li>
 *  Script based SQL tests consisting of:<p>
 *  <code>TestSelf.txt</code> : the main test script.<p>
 *  <code>TestSelfXXXX.txt</code> : specialised test scripts that
 *  will be run in alphabetical filename order.<p>
 *</li>
 * </ul>
 *
 *  Tests can be added by writing new scripts in the standard format described
 *  in <code>TestSelf.txt</code> and naming the script in the correct format,
 *  <code>TestSelfXXXX.txt</code>, where XXXX is the description of the new
 *  test.<p>
 *  The database can be shutdown at the end of each script (using the
 *  SHUTDOWN command). This allows a test to be divided into two or more
 *  scripts in order to test the persistence mechanism for both objects
 *  created via DDL or data stored in the database. An example of this
 *  is the set of supplied scripts, <code>TestSelfCreate.txt</code>,
 *  <code>TestSelfModify.txt</code> and <code>TestSelfVerify.txt</code>.
