Omniscient Debugging

przez

Debugger dla aplikacji napisanych w Javie

What if your debugger could go „go backwards in time?” Would that make debugging easier? By simply recording all variable assignments, it is possible to do essentially this. This is the underlying idea for omniscient debugging. The amazing part is that significantly large programs can be debugged in this fashion — Ant, JUnit, the debugger itself.
