Exploring DDU in Practice

The quality of test suites is commonly measured using adequacy metrics that focus on error detection, like test coverage. However, the diagnostic performance of spectrum-based fault localization techniques, that can potentially reduce the time spent on debugging, rely on diagnosability of test suites --- the property of faults to be easily and...

Revisiting the Practical Use of Automated Software Fault Localization Techniques

In the last two decades, a great amount of effort has been put in researching automated debugging techniques to support developers in the debugging process. However, in a widely cited user study published in 2011, Parnin and Orso found that research in automated debugging techniques made assumptions that do not hold in practice, and suggested...
