- Background. When delivering an embedded product, such as a mobile phone, third party products, like games, are often bundled with it in the form of Java MIDlets. To verify the compatibility be- tween the runtime platform and the MIDlet is a labour-intensive task, if input data should be manually generated for thousands of MIDlets. Aim. In order to make the verification more efficient, we investigate four different automated input generation methods which do not require extensive modeling; random, feedback based, with and without a constant startup sequence. Method. We evaluate the methods in a factorial design experiment with manual input generation as a reference. One original experiment is run, and a partial replication. Result. The results show that the startup sequence gives good code coverage values for the selected MIDlets. The feedback method gives somewhat better code coverage than the random method, but requires real-time code coverage measurements, which decreases the run speed of the tests. Conclusion The random method with startup sequence is the best trade-off in the current setting.

ESS Control System Data Lab - Executive Summary
- 2021
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Driven by the idea to use alarm data to explore machine learning across Industry 4.0 applications, the goal of this pilot study was to explore how to collect, store, manage and share data from the ESS Control System. Generally, we seek to make any control system data available for research and innovation but started with alarms as a feasible domain in which to explore machine learning. The goals were threefold, each explored in a work package:1. How to govern a data ecosystem, and which tools are needed to support it?2. How can alarm data be interpreted across industrial contexts, i.e., which meta dataand reference models are needed?3. How can data sharing be practically and legally handled at ESS?In summary, we identify a set of potential alleys for continued work to foster industrial innovation and collaboration in a control system data ecosystem with ESS as a catalyst.

A Case Study on Quality Monitoring in a Highly Iterative Software Development Process
- 2005
-
Ingår i: Fifth Conference on Software Engineering Research and Practice in Sweden.
-
Konferensbidrag (refereegranskat)abstract
- This paper describes a case study on quality monitoring conducted in an industrial environment. In a highly iterative project, everything seems to happen at the same time; analysis, design and testing. In the study, data collected from three software development projects is analyzed, to investigate which characteristics are stable across projects and feature groups of the product. Design and test activities are conducted in parallel in the incremental development environment, adding features to a product base continuously. The contribution of the paper is multifold, detailing the case study methodology used with its subgoals and procedure, presenting the lessons learned from the study, and the results as such from the case study give insights into a complex development environment and the trends of the retrieved data, which e.g. are used for a defect prediction model.

A replicated quantitative analysis of fault distributions in complex software systems
- 2007
-
Ingår i: IEEE Transactions on Software Engineering. - 0098-5589. ; 33:5, s. 273-286
-
Tidskriftsartikel (refereegranskat)abstract
- To contribute to the body of empirical research on fault distributions during development of complex software systems, a replication of a study of Fenton and Ohlsson is conducted. The hypotheses from the original study are investigated using data taken from an environment that differs in terms of system size, project duration, and programming language. We have investigated four sets of hypotheses on data from three successive telecommunications projects: 1) the Pareto principle, that is, a small number of modules contain a majority of the faults ( in the replication, the Pareto principle is confirmed), 2) fault persistence between test phases ( a high fault incidence in function testing is shown to imply the same in system testing, as well as prerelease versus postrelease fault incidence), 3) the relation between number of faults and lines of code ( the size relation from the original study could be neither confirmed nor disproved in the replication), and 4) fault density similarities across test phases and projects ( in the replication study, fault densities are confirmed to be similar across projects). Through this replication study, we have contributed to what is known on fault distributions, which seem to be stable across environments.

A Spiral Process Model for Case Studies on Software Quality Monitoring - Method and Metrics
- 2007
-
Ingår i: Software Process Improvement and Practice. - 1077-4866. ; 12:2, s. 125-140
-
Tidskriftsartikel (refereegranskat)abstract
- This article presents a spiral process model for an iterative case study on quality monitoring, conducted in an industrial environment. In a highly iterative project, everything seems to happen at the same time: analysis, design and testing. We propose a spiral process model for case studies, and present a study conducted according to the proposed process. In the study, metrics collected from three software development projects are analysed to investigate which characteristics are stable across projects and feature groups of the product. The contribution of the article is multi-fold, detailing the case study methodology used with its sub-goals and procedures. Furthermore, the article presents the metrics collected and the results as such from the case study, which gives insights into a complex development environment and the trends of the retrieved data. The analysed data serve as feedback to the project staff to facilitate identification of software process improvement. The data have also been used for defect prediction.

An experimental evaluation of inspection and testing for detection of design faults
- 2003
-
Ingår i: Proceedings 2003 International Symposium on Empirical Software Engineering. ISESE 2003. - 0769520022 ; , s. 174-184

Konferensbidrag (refereegranskat)abstract
- The two most common strategies for verification and validation, inspection and testing, are in a controlled experiment evaluated in terms of their fault detection capabilities. These two techniques are in the previous work compared applied to code. In order to compare the efficiency and effectiveness of these techniques on a higher abstraction level than code, this experiment investigates inspection of design documents and testing of the corresponding program, to detect faults originating from the design document. Usage-based reading (UBR) and usage-based testing (UBT) were chosen for inspections and testing, respectively. These techniques provide similar aid to the reviewers as to the testers. The purpose of both fault detection techniques is to focus the inspection and testing from a user's viewpoint. The experiment was conducted with 51 Master's students in a two-factor blocked design; each student applied each technique once, each application on different versions of the same program. The two versions contained different sets of faults, including 13 and 14 faults, respectively. The general results from this study show that when the two groups of subjects are combined, the efficiency and effectiveness are significantly higher for usage-based reading and that testing tends to require more learning. Rework is not taken into account, thus the experiment indicates strong support for design inspection over testing

Evaluating the impact of software process simulations - a case study
- 2004
-
Ingår i: 5th International Workshop on Software Process Simulation and Modeling (ProSim 2004) W11L Workshop - 26th International Conference on Software Engineering. - 0863414265 ; , s. 217-221

Konferensbidrag (refereegranskat)abstract
- The software process simulation research field has been growing in recent years. Much effort has been used for developing detailed software process simulation models. However, few studies are available characterizing the effect process simulation models could have when introduced to an organization. Furthermore, most published work in this area has been focused on the effect that the models have for project management. This motivates a study with focus on other categories of project staff, and evaluation of the benefits that could be gained by the introduction of a software process model. We describe an ongoing qualitative study evaluating the impact of the introduction of a software process simulation model in an industrial setting. The focus is to analyse the impact the model has among developers and testers in a specific organization, and to evaluate the model's suitability as a tool for gaining better understanding of the dynamic process behaviour among the study participants

Investigating Test Teams' Defect Detection in Function Test
- 2007
-
Ingår i: ESEM07 - First International Symposium on Empirical Software Engineering and Measurement, September, 20-21, 2007, Madrid, Spain. - 1938-6451. - 9780769528861 ; , s. 458-460
-
Konferensbidrag (refereegranskat)abstract
- In a case study, the defect detection for functional test teams is investigated. In the study it is shown that the test teams not only discover defects in the features under test that they are responsible for, but also defects in interacting components, belonging to other test teams’ features. The paper presents the metrics collected and the results as such from the study, which gives insights into a complex development environment and highlights the need for coordination between test teams in function test.
