- KonferenzbeitragAn aspect-based environment for COTS component testing(Testing of component-based systems and software quality, 2004) Polo, Macario; Cechich, AlejandraComponent qualification is one of the major steps in the development of component-based applications. Several techniques are used to enrich documentation by structuring and classifying components' metadata. In that line, aspect information has been used to help implement better component interfaces and to encode knowledge of components' capabilities. In this paper, we describe an environment to generate and execute aspect-dependent test cases, which is based on an aspect-based categorisation of information for testing.
- KonferenzbeitragAssessing and interpreting object-oriented software complexity with structured and independent metrics(Testing of component-based systems and software quality, 2004) Neumann, Roland; Klemann, DennisObject-oriented software complexity is difficult to assess due to its manifold influences from cognition science or algorithmic complexity theory. A practical process for a structured complexity assessment is presented in this paper. It starts with considerations for measurement and data preparation. Using mathematical transformation techniques, independent complexity metrics are gained. With these results, complexity aspects of a software system can be defined. This makes a complexity comparison through system classes possible, which helps getting an overview on large systems. These process steps are then illustrated with an industrial example.
- KonferenzbeitragCate: A system for analysis and test of Java card applications(Testing of component-based systems and software quality, 2004) Pfahler, Peter; Günther, JürgenCate is a domain-specific testing environment. It integrates both static and dynamic analyzes that are designed for Java Card application software. Cate supports the test process by analyzing the command/response behavior of the software, by performing test coverage analysis and by providing tools to visualize the analysis results. This paper gives a concise overview over the system which is successfully employed in the area of smart card development for mobile phones.
- KonferenzbeitragGeneric environment for full automation of benchmarking(Testing of component-based systems and software quality, 2004) Kalibera, Tomáš; Bulej, Lubomír; Tůma, PetrRegression testing is an important part of software quality assurance. We work to extend regression testing to include regression benchmarking, which applies benchmarking to detect regressions in performance. Given the specific requirements of regression benchmarking, many contemporary benchmarks are not directly usable in regression benchmarking. To overcome this, we present a case for designing a generic benchmarking environment that will facilitate the use of contemporary benchmarks in regression benchmarking, analyze the requirements and propose architecture of such an environment.
- KonferenzbeitragImproving software quality through refactoring by means of didactical augmented experience(Testing of component-based systems and software quality, 2004) Rech, Jörg; Ras, Eric; Jedlitschka, AndreasIn agile software development refactoring is an important phase for the continuous improvement of software quality. Unfortunately, the application of refactorings is very subjective and heavily based on the expertise of the developers resulting in an unstable quality assurance. In this paper, we present an experiencebased approach for the semi-automatic and goal-oriented refactoring of software systems based on didactical augmented experiences, following the experience factory paradigm. This approach promises the accelerated acquisition, (re-) use, and learning of knowledge in the refactoring process.
- KonferenzbeitragInspections in small projects(Testing of component-based systems and software quality, 2004) Iisakka, JuhaPractically all inspection and review methods focus on projects for developing new software that involve numerous people, but software companies also have small projects on which only a few people are working, e.g. maintenance-oriented changes to existing software systems. Unfortunately, these small projects do not necessarily have the power to implement inspections efficiently. This paper raises certain problems that small projects have with inspections and discusses how different forms of inspection are suitable for small projects.
- KonferenzbeitragMeasuring component performance using a systematic approach and environment(Testing of component-based systems and software quality, 2004) Gao, Jerry; Ravi, Chandra S.; Raquel, EspinozaAs more third-party software components are available in the commercial market, more people begin to use the component-based software engineering approach to developing component-based programs. Since most e-business and e-commerce application systems are net-centered distributed systems, customers usually have very restricted system performance requirements. Hence, performance testing and evaluation of software components becomes a critical task for component-based software. Although a lot of research efforts have been devoted to analysis and design methods of component-based software, only a few research papers address the issues and systematic solutions to performance testing and measurement for modern components. This paper proposes a systematic solution and environment to support performance measurement for software components. The objective is to provide a plug-in-and-measure approach to evaluate component performance, including functional speed, throughput, availability, reliability and resource utilization. It reports the development effort on constructing a distributed performance evaluation environment for software components based on a set of well-defined performance evaluation metrics and techniques. In addition, some application examples and case study results are reported.
- KonferenzbeitragMeasuring the effectiveness of software testing(Testing of component-based systems and software quality, 2004) Sneed, Harry M.In 1978 Harry Sneed set up the first commercial software test laboratory in Budapest charging DM 75,- per test case and DM 100,- for each error found. The laboratory was used to test the Integrated Transport Steuerung system of the German railroad and the BS2000 operating system of Siemens. Today, some 26 years later, managers are looking for a means to justify the cost of testing. While working as a test consultant for a Viennese software house from 1998 until 2003, Harry Sneed conceived a set of metrics for measuring the effectiveness of the test operations there. These metrics were intended to measure the performance of the test department, but they are equally valid for measuring test operations anywhere. In fact, with these metrics it should be possible to convert software testing from an art as perceived by Glenford Meyers in 1975 to a science as defined by Lord Kelvin in 1875. The metrics were obtained using the Goal/Question/Metric Method of Basili and Rombach and were refined through three years of practical application. In effect, they are a continuation of the test measurement work Sneed began as a young test entrepreneur in 1978. They are supported by a set of tools designed for both static and dynamic analysis as well as for evaluating the results of both. Working as a test team leader at the Wirtschaftskammer in Vienna, Sneed applied these metrics to successfully predict the test effort required to test a complex web application. From this presentation the attendants will be exposed to the experience of 30 years of software testing.
- KonferenzbeitragAn optimum, system-based component testing approach for evaluating software reliability(Testing of component-based systems and software quality, 2004) Rajgopal, Jayant; Mazumdar, MainakIn a component testing approach for evaluating system reliability, one tests units of the components or subsystems that make up a larger system in order to draw conclusions about the reliability of the latter. An optimum, system-based component test plan explicitly account for the relationship between component and system reliabilities and also minimizes total testing effort. This paper reviews the main features of such plans and describes an application to reliability testing of a software system that is made up of several different components/modules.
- KonferenzbeitragProperty-oriented testing: An approach to focusing testing efforts on behaviours of interest(Testing of component-based systems and software quality, 2004) Li, Shuhao; Qi, ZhichangThe behaviours of reactive systems are characterized by events, conditions, actions, and information flows. Complex reactive systems further exhibit hierarchy and concurrency. Since there usually exist numerous behaviours in such systems, they can hardly receive both comprehensive and in-depth testing. This paper presents a property-oriented testing method for reactive systems. UML state machine is employed to model the system under test (SUT) and temporal logic is used to specify the property to be tested. Targeted test sequences are derived from the model according to the given property. Based on this method, a property-oriented testing tool is implemented. Experiment results indicate that testing efforts can be focused on behaviours of interest of the SUT and thus usually only a small portion of the total behaviours needs to be tested. This method suits well the occasions when the testers have to focus on only critical properties of the SUT in case limited project budget is available. After appropriate extensions, this method can also be applied to real-time systems and systems with parameterized events.
