/**
 * Test intended for use in the continuous integration system that checks whether the
 * schema reference file (for whichever database the tests are being run against)
 * is in sync with the actual schema. If the test fails (and the schema comparator is
 * in working order) then the most likely cause is that a new up-to-date schema reference file
 * needs to be created.
 * <p>
 * Schema reference files are created using the {@link DbToXML} tool.
 * <p>
 * Note: if no reference file exists then the test will pass, this is to allow piece meal
 * introduction of schmea reference files.
