Study Finds Software Testers Often Misjudge Which Techniques Work Best

An experimental study shows that developers often misperceive which software testing techniques are most effective for them. While techniques differ in actual defect detection performance, participants’ perceptions fail to reliably align with reality, leading to measurable effectiveness losses. The findings suggest that relying on personal judgment when choosing testing techniques carries a real cost and that further research is needed to understand the roots of these misperceptions.
