Found in: IEEE Transactions on Software Engineering
By Richard Berntsson Svensson,Tony Gorschek,Bjorn Regnell,Richard Torkar,Ali Shahrokni,Robert Feldt
Issue Date:July 2012
pp. 923-935
In order to create a successful software product and assure its quality, it is not enough to fulfill the functional requirements, it is also crucial to find the right balance among competing quality requirements (QR). An extended, previously piloted, inter...
 
Overcoming the Equivalent Mutant Problem: A Systematic Literature Review and a Comparative Experiment of Second Order Mutation
Found in: IEEE Transactions on Software Engineering
By Lech Madeyski,Wojciech Orzeszyna,Richard Torkar,Mariusz Jozala
Issue Date:January 2014
pp. 23-42
Context. The equivalent mutant problem (EMP) is one of the crucial problems in mutation testing widely studied over decades. Objectives. The objectives are: to present a systematic literature review (SLR) in the field of EMP; to identify, classify and impr...
   
Search-Based Prediction of Fault Count Data
Found in: Search Based Software Engineering, International Symposium on
By Wasif Afzal, Richard Torkar, Robert Feldt
Issue Date:May 2009
pp. 35-38
Symbolic regression, an application domain of genetic programming (GP), aims to find a function whose output has some desired property, like matching target values of a particular data set. While typical regression involves finding the coefficients of a pr...
 
Practitioner-Oriented Visualization in an Interactive Search-Based Software Test Creation Tool
Found in: 2013 20th Asia-Pacific Software Engineering Conference (APSEC)
By Bogdan Marculescu,Robert Feldt,Richard Torkar
Issue Date:December 2013
pp. 87-92
Search-based software testing uses meta-heuristic search techniques to automate or partially automate testing tasks, such as test case generation or test data generation. It uses a fitness function to encode the quality characteristics that are relevant, f...
 
Search-based Prediction of Fault-slip-through in Large Software Projects
Found in: Search Based Software Engineering, International Symposium on
By Wasif Afzal, Richard Torkar, Robert Feldt, Greger Wikstrand
Issue Date:September 2010
pp. 79-88
A large percentage of the cost of rework can be avoided by finding more faults earlier in a software testing process. Therefore, determination of which software testing phases to focus improvements work on, has considerable industrial interest. This paper ...
 
A Comparative Evaluation of Using Genetic Programming for Predicting Fault Count Data
Found in: Software Engineering Advances, International Conference on
By Wasif Afzal, Richard Torkar
Issue Date:October 2008
pp. 407-414
There have been a number of software reliability growth models (SRGMs) proposed in literature. Due to several reasons, such as violation of models' assumptions and complexity of models, the practitioners face difficulties in knowing which models to apply i...
 
Suitability of Genetic Programming for Software Reliability Growth Modeling
Found in: Computer Science and its Applications, International Symposium on
By Wasif Afzal, Richard Torkar
Issue Date:October 2008
pp. 114-117
Genetic programming (GP) has been found to be effective in finding a model that fits the given data points without making any assumptions about the model structure. This makes GP a reasonable choice for software reliability growth modeling. This paper disc...
 
A Survey on Testing and Reuse
Found in: Software Science, Technology and Engineering, IEEE International Conference on
By Richard Torkar, Stefan Mankefors
Issue Date:November 2003
pp. 164
This survey tries to give an account of what type of trends exist today in software reuse and testing. The focus was to try to find out how developers use different tools today and what tools are lacking, especially in the field of reuse and testing. The p...
 
Searching for Cognitively Diverse Tests: Towards Universal Test Diversity Metrics
Found in: Software Testing Verification and Validation Workshop, IEEE International Conference on
By Robert Feldt, Richard Torkar, Tony Gorschek, Wasif Afzal
Issue Date:April 2008
pp. 178-186
Search-based software testing (SBST) has shown a po- tential to decrease cost and increase quality of testing- related software development activities. Research in SBST has so far mainly focused on the search for isolated tests that are optimal according t...
 
Incorporating Metrics in an Organizational Test Strategy
Found in: Software Testing Verification and Validation Workshop, IEEE International Conference on
By Wasif Afzal, Richard Torkar
Issue Date:April 2008
pp. 305-315
An organizational level test strategy needs to incorporate metrics to make the testing activities visible and available to process improvements. The majority of testing measurements that are done are based on faults found in the test execution phase. In co...
 
Indirect effects in evidential assessment: a case study on regression test technology adoption
Found in: Proceedings of the 2nd international workshop on Evidential assessment of software technologies (EAST '12)
By Emelie Engström, Richard Torkar, Robert Feldt
Issue Date:September 2012
pp. 15-20
Background: There is a need for efficient regression testing in most software development organizations. Often the proposed solutions involve automation. However, despite this being a well researched area, research results are rarely applied in industrial ...
     
Search-based software testing and test data generation for a dynamic programming language
Found in: Proceedings of the 13th annual conference on Genetic and evolutionary computation (GECCO '11)
By Richard Torkar, Robert Feldt, Stefan Mairhofer
Issue Date:July 2011
pp. 1859-1866
Manually creating test cases is time consuming and error prone. Search-based software testing can help automate this process and thus reduce time and effort and increase quality by automatically generating relevant test cases. Previous research has mainly ...
     
Towards individualized software engineering: empirical studies should collect psychometrics
Found in: Proceedings of the 2008 international workshop on Cooperative and human aspects of software engineering (CHASE '08)
By Lefteris Angelis, Maria Samuelsson, Richard Torkar, Robert Feldt
Issue Date:May 2008
pp. 49-52
Even though software is developed by humans, research in software engineering primarily focuses on the technologies, methods and processes they use while disregarding the importance of the humans themselves. In this paper we argue that most studies in soft...
