Regression testing is an important part of software maintenance, but it can also be very expensive. To reduce this expense, software testers may prioritize their test cases so that those that are more important are run earlier in the regression testing process. Previous work has shown that prioritization can improve a test suite’s rate of fault detection, but the assessment of prioritization techniques has been limited to hand-seeded faults, primarily due to the belief that such faults are more realistic than automatically generated (mutation) faults. A recent empirical study, however, suggests that mutation faults can be representative of real faults. We have therefore designed and performed a controlled experiment to assess the ability of prioritization techniques to improve the rate of fault detection techniques, measured relative to mutation faults. Our results show that prioritization can be effective relative to the faults considered, and they expose ways in which that effectiveness can vary with characteristics of faults and test suites. We also compare our results to those collected earlier with respect to the relationship between hand-seeded faults and mutation faults, and the implications this has for researchers performing empirical studies of prioritization.

In 2008, the Center for Applied Rural Innovation conducted a comprehensive five-year evaluative study of the NebraskaEDGE program. Two different surveys were sent to former NebraskaEDGE training participants who were enrolled in the EDGE training courses between the Fall of 2002 and Spring of 2007. The objective of the surveys were to: 1) measure changes in participant knowledge and skills as a result of the entrepreneurial training class, and 2) better learn how participants applied their new skills to their businesses and what those impacts were on the businesses.
