//  Revision 1.13  2003/02/13 08:23:08  rogeeff
//  C strings eliminated
//  type: virtual method -> property
//  const added to user test case shared instance reference
//
//  Revision 1.12  2002/12/08 17:51:04  rogeeff
//  notion of number of stages is separated from number of test cases, so that
//  parameterized test case in reported as one test case
//  fixed bug in both parameterized function/class test cases with not iterating
//  parameter iterator if exception occured
//  switched to use c_string_literal
