HCL OneTest Embedded, more than anything else, exposes two vital issues:
True, error free code is guaranteed only through extremely vigilant testing and runtime analysis. Skip any part and defects might fall through - defects you either repair now, when you have time, or later, when code freeze looms and your reputation is on the line.
With Test RealTime, this vigilance is easily accomplished. You achieve full testing and runtime analysis with minimal distraction and minimal focus on tedious, time-consuming tasks.
Again - is it possible to develop a defect-free product? It's certainly not possible if you don't test. But if you do test, and test well, who knows...
