Describe the feature you'd like

1. Pattern matching only works for SQL errors: @pattern flag fails for result sets because StmtResult.regularMatch() only checks errorMessage (null for result sets). Pattern stored in orginalRSText is ignored.

2. Serial execution only: Tests run sequentially in a simple loop, no parallelization support. Cannot leverage multi-core systems.

3. Poor multi-line output handling: ResultParser.convertToRSSet() uses simple split() which breaks when column values contain separator characters. No escape handling.
