Testing as a road to confidence-from-use

The role of testing in software-based systems has changed significantly in the past few years. The 2013 release of the ISO/IEC 29119 software testing standard reflects this change, though the move towards risk-based rather than requirement-based testing had already been adopted, either tacitly or explicitly, by most test groups. The testing of a software system can now be seen as a means of producing evidence of confidence-in-use rather than a demonstration of the correctness of the system.
