  • Using Exploration Focused Techniques to Augment Search-Based Software Testing: An Experimental Evaluation
  • 2016
  • Ingår i: 2016 9th Ieee International Conference on Software Testing, Verification and Validation. - 2381-2834. - 978-1-5090-1827-7 ; s. 69-79

    • Search-based software testing (SBST) often uses objective-based approaches to solve testing problems. There are, however, situations where the validity and completeness of objectives cannot be ascertained, or where there is insufficient information to define objectives at all. Incomplete or incorrect objectives may steer the search away from interesting behavior of the software under test (SUT) and from potentially useful test cases. This papers investigates the degree to which exploration-based algorithms can be used to complement an objective-based tool we have previously developed and evaluated in industry. In particular, we would like to assess how exploration-based algorithms perform in situations where little information on the behavior space is available a priori. We have conducted an experiment comparing the performance of an exploration-based algorithm with an objective-based one on a problem with a high-dimensional behavior space. In addition, we evaluate to what extent that performance degrades in situations where computational resources are limited. Our experiment shows that exploration-based algorithms are useful in covering a larger area of the behavior space and result in a more diverse solution population. Typically, of the candidate solutions that exploration-based algorithms propose, more than 80% were not covered by their objective-based counterpart. This increased diversity is present in the resulting population even when computational resources are limited. We conclude that exploration-focused algorithms are a useful means of investigating high-dimensional spaces, even in situations where limited information and limited resources are available.

  • Prioritization of quality requirements: State of practice in eleven companies
  • 2011
  • Ingår i: 2011 IEEE 19th International Requirements Engineering Conference, RE 2011; Trento; 29 August 2011 through 2 September 2011. - 978-145770923-4 ; s. 69-78

    • Requirements prioritization is recognized as an important but challenging activity in software product development. For a product to be successful, it is crucial to find the right balance among competing quality requirements. Although literature offers many methods for requirements prioritization, the research on prioritization of quality requirements is limited. This study identifies how quality requirements are prioritized in practice at 11 successful companies developing software intensive systems. We found that ad-hoc prioritization and priority grouping of requirements are the dominant methods for prioritizing quality requirements. The results also show that it is common to use customer input as criteria for prioritization but absence of any criteria was also common. The results suggests that quality requirements by default have a lower priority than functional requirements, and that they only get attention in the prioritizing process if decision-makers are dedicated to invest specific time and resources on QR prioritization. The results of this study may help future research on quality requirements to focus investigations on industry-relevant issues.

  • Properties of stereotypes from the perspective of their role in designs
  • 2005
  • Konferensbidrag (refereegranskat)abstract
    • Stereotypes in object-oriented software development can be perceived in various ways and they can be used for various purposes. As a consequence of these variations, assessing quality of stereotypes needs to be purpose-specific. In this paper we identify eight types of stereotypes and provide a set of criteria for assessing quality of stereotypes. The criteria for each type are formed by a set of properties that characterizes its stereotypes. The identified types are based on the purpose of each stereotype (its role in designs) and its expressiveness. We identified the types of stereotypes and their properties in an empirical way by investigating stereotypes from UML profiles used in industrial software development. The properties are intended to be used in our further research for developing guidelines for creating and using stereotypes in a more efficient way.

  • Selecting creativity techniques for creative requirements: An evaluation of four techniques using creativity workshops
  • 2015
  • Ingår i: 23rd IEEE International Requirements Engineering Conference, RE 2015, Ottawa, Canada, 24-28 August. - 978-146736905-3 ; s. 66-75
  • Konferensbidrag (refereegranskat)abstract
    • Requirements engineering is recognized as a creative process where stakeholders jointly discover new creative ideas for innovative and novel products that eventually are expressed as requirements. This paper evaluates four different creativity techniques, namely Hall of Fame, Constraint Removal, Brainstorming, and Idea Box, using creativity workshops with students and industry practitioners. In total, 34 creativity workshops were conducted with 90 students from two universities, and 86 industrial practitioners from six companies. The results from this study indicate that Brainstorming can generate by far the most ideas, while Hall of Fame generates most creative ideas. Idea Box generates the least number of ideas, and the least number of creative ideas. Finally, Hall of Fame was the technique that led to the most number of requirements that was included in future releases of the products.

  • Information sources and their importance to prioritize test cases in heterogeneous systems context
  • 2014
  • Ingår i: Communications in Computer and Information Science. - 1865-0929. - 978-3-662-43895-4 ; 425, s. 86-98
  • Konferensbidrag (refereegranskat)abstract
    • Context: Testing techniques proposed in the literature rely on various sources of information for test case selection (e.g., require- ments, source code, system structure, etc.). The challenge of test selection is amplified in the context of heterogeneous systems, where it is unknown which information/data sources are most important. Contribution: (1) Achieve in-depth understanding of test processes in heterogeneous systems; (2) Elicit information sources for test selection in the context of heterogeneous systems. (3) Capture the relative importance of the identified information sources. Method: Case study research is used for the elicitation and understanding of which information sources are relevant for test case privatization, followed by an exploratory survey capturing the relative importance of information sources for testing heterogeneous systems. Results: We classified different information sources that play a vital role in the test selection process, and found that their importance differs largely for the different test levels observed in heterogeneous testing. However, overall all sources were considered essential in test selection for heterogeneous systems. Conclusion: Heterogeneous system testing requires solutions that take all information sources into account when suggesting test cases for selection. Such approaches need to be developed and compared with existing solutions.

  • Group Maturity and Agility, Are They Connected? - A Survey Study
  • 2015
  • Ingår i: EUROMICRO Conference on Software Engineering and Advanced Applications (SEAA 2015), August 26-28. - 978-1-4673-7585-6 ; 41, s. 1-8
  • Konferensbidrag (refereegranskat)abstract
    • The focus on psychology has increased within software engineering due to the project management innovation "agile development processes". The agile methods do not explicitly consider group development aspects; they simply assume what is described in group psychology as mature groups. This study was conducted with 45 employees and their twelve managers (N=57) from two SAP customers in the US that were working with agile methods, and the data were collected via an online survey. The selected Agility measurement was correlated to a Group Development measurement and showed significant convergent validity, i.e., a more mature team is also a more agile team. This means that the agile methods probably would benefit from taking group development into account when its practices are being introduced.

  • An initial analysis of differences in software engineers' attitudes towards organizational change
  • 2016
  • Ingår i: 9th International Workshop on Cooperative and Human Aspects of Software Engineering, CHASE 2016; Austin; United States; 16 May 2016. - 978-145034155-4 ; s. 1-7

    • The ability to manage change is important in software engineering organizations, where rapid progress in technologies and constantly evolving methodologies create a turbulent environment. Research has identified employees’ attitudes towards organizational change as a key factor in the change process. Nonetheless, few studies exist that explore such attitudes in a software engineering context. The nature of change efforts is such that they often do not equally affect the various roles in the organization, which indicates that the roles may hold different attitudes. This study aimed to verify the existence of these presumed differences in attitudes towards organizational change between roles in a software engineering organization and to identify factors that contribute to these differences. The result of a survey (N=51) confirmed that there were significant differences, and that the software developers had a more positive attitude towards change and had deeper knowledge about the intended outcome compared to the line managers. The result of in-depth interviews (N=11) revealed that the software engineers evaluate the planned change in relation to the norms, values and standards of their peer group, meaning that an employee will have a positive attitude towards a change if its result is likely to make, or has made, it easier for him/her to uphold the peer group’s norms and values.
