On the Use of Mutation Faults in Empirical Assessments of Test Case Prioritization Techniques

Hyunsook Do, G. Rothermel
2006 IEEE Transactions on Software Engineering  
More importantly, a comparison of our results with those collected using hand-seeded faults reveals several implications for researchers performing empirical studies of test case prioritization techniques  ...  A recent empirical study, however, suggests that mutation faults can be representative of real faults and that the use of hand-seeded faults can be problematic for the validity of empirical results focusing  ...  ACKNOWLEDGMENTS Steve Kachman of the University of Nebraska-Lincoln Statistics Department provided assistance with our statistical analysis.  ...

Environmental cost of using poor decision metrics to prioritize environmental projects

David J. Pannell, Fiona L. Gibson
2016 Conservation Biology  
We estimated the magnitudes of these losses for various metrics that deviate from theory in ways that are common in practice.  ...  The cost of using poor prioritization metrics (in terms of lost environmental values) was often highup to 80% in the scenarios we examined. The cost was greater when the budget was smaller.  ...  Acknowledgments We are grateful to the Australian Research Council Centre of Excellence for Environmental Decisions for funding support.  ...

On Simulation and Design of Parallel-Systems Schedulers: Are We Doing the Right Thing?

E. Shmueli, D.G. Feitelson
2009 IEEE Transactions on Parallel and Distributed Systems  
As a consequence, all schedulers have evolved to optimize the packing of jobs in the schedule, as a mean to improve a number of performance metrics that are conjectured to be correlated with user satisfaction  ...  We propose an alternative simulation methodology called site-level simulation, in which the workload for the evaluation is generated dynamically by user-models that interact with the system.  ...  We investigate the reason for this exceptional improvement and show that it stems from CREASY's ability to maintain long user sessions under high loads.  ...

Paolo Tonella, Paolo Avesani, Angelo Susi
2006 Conference on Software Maintenance, Proceedings of the  
In this paper, we propose a test case prioritization technique that takes advantage of user knowledge through a machine learning algorithm, Case-Based Ranking (CBR).  ...  Prioritizing the test cases so as to optimize the achievement of the testing goal has potentially a positive impact on the testing costs, especially when the test execution time is long.  ...  In order to investigate the behavior of CBR at variable test suite size, we sub-sampled the available suites and we produced test suites with a size ranging from 10 to 100, at increments of 10.  ...
