Previous research in defect prediction has proposed approaches to determine which files require additional testing resources. However, practitioners typically create tests at a higher level of abstraction, which may span across many files. In this paper, we study software testing, especially test resource prioritization, from a different perspective. We use topic models to generate topics that provide...
Unit testing has been considered as having a key role in building high quality software, and therefore it has been widely used in practice. However, data on the relationship between unit testing and aspects of software quality remain scarce. A survey study with 235 survey responses from seven organizations was conducted in order to understand the correlation between practitioners' perception of code...
Spreadsheets often contain faults that are difficult to localize. Spectrum-based Fault Localization (SFL) assists users in the fault localization process by ranking cells by their suspiciousness to contain a fault. Since the ranking of the basic SFL approach is often imprecise, we propose three techniques to improve it, i.e., dynamic cones, grouping, and tie-breaking. We evaluate these techniques...
The testing process of a low noise RF pre-amp in most of the semiconductor fabrication industries is either fully manual or employs expensive test systems. An efficient and low cost automated testing system is elucidated in this paper. The design and development of the automated RF test system is realized. The whole process involves the development of an Automated Test System (ATE) and a software...
Applications are generally written assuming a predictable and well-behaved OS. In practice, they experience unpredictable misbehavior at the OS level and across OSes: different OSes can handle network events differently, APIs can behave differently across OSes, and OSes may be compromised or buggy. This unpredictability is challenging because its sources typically manifest during deployment and are...
Due to changes in the development practices at Axis Communications, towards continuous integration, faster regression testing feedback is needed. The current automated regression test suite takes approximately seven hours to run which prevents developers from integrating code changes several times a day as preferred. Therefore we want to implement a highly selective yet accurate regression testing...
Software bugs contribute to the cost of ownership for consumers in a software-driven society and can potentially lead to devastating failures. Software testing, including functional testing and structural testing, remains a common method for uncovering faults and assessing dependability of software systems. To enhance testing effectiveness, the developed artifacts (requirements, code) must be designed...
Test case prioritization for regression testing is an approach that schedules test cases to improve the efficiency of service-oriented workflow application testing. Most of existing prioritization approaches range test cases according to various metrics (e.g., Statement coverage, path coverage) in different application context. Service-oriented workflow applications orchestrate web services to provide...
The objective of the work described is to accurately predict, as early as possible in the software lifecycle, how reliably a new software release will behave in the field. The initiative is based on a set of innovative mathematical models that have consistently shown a high correlation between key in-process metrics and our primary customer experience metric, SWDPMH (Software Defects per Million Hours...
RESTCONF is a management protocol, based on REST principles, currently under design at the IETF. In this paper, we present our solution for automating conformance testing of RESTCONF agents. The solution takes as input the set of YANG modules supported by the agent and automatically generates test cases based on the YANG definitions. Test cases are consumed by a test execution environment, which issues...
Software quality is one of the most pressing concerns for nearly all software developing companies. At the same time, software companies also seek to shorten their release cycles to meet market demands while maintaining their product quality. Identifying problematic code areas becomes more and more important. Defect prediction models became popular in recent years and many different code and process...
In 1998 NESMA published an alternative approach to establish the functional size of software enhancement projects. The aim of the approach was to be able to use productivity data from software development to estimate software enhancement. This approach has been highly debated, since it is not a pure functional size measurement method in the ISO/IEC 14143 definition. The approach is in use all over...
In order to evaluate balancing ability in each direction more objectively and analyze the correlations between balance ability and human basic information such as gender, height and weight, the complete dynamics model of balance process under external excitation was simplified as two order linear system reasonably in this study. The evaluation system based on visual stimulation was built to provide...
Our experiences with industrial software development projects have often revealed that requirements change even after their formal approvals. Although the requirements are never stable, proactive identification of potentially changeable or deferrable requirements, and estimation of their impacts early in a project can be useful in minimizing the risks and cost overruns. In practice, the decisions...
One of the most significant problems faced by project managers is to effectively distribute the project resources and effort among the various project activities. Most importantly, project success depends on how well, or how balanced, the work effort is distributed among the project phases. This paper aims to obtain useful information regarding the correlation of the composition of effort attributed...
With the large-scale distributed system plays an increasingly important role in such fields as national security, critical infrastructure and social life, its vulnerability analysis problem has become a growing focus nowadays. As a vulnerability analysis object, a multi-layer model is put forward firstly, and then a multi-dimension vulnerability analysis framework of large-scale distributed system...
There is a lack of published studies providing empirical support for the assumption at the heart of product line development, namely, that through structured reuse later products will be less fault-prone. This paper presents results from an empirical study of pre-release fault and change proneness from four products in an industrial software product line. The objectives of the study are (1) to determine...
This paper presents the initial results of a study of the evolution of students' knowledge of software engineering from the beginning to the end of a master's degree curriculum in software engineering. Students were presented with a problem involving the initiation of a complex new project at the beginning of the program and again at the end of the program's formal coursework. After considering the...
In software development determining the release readiness plays an essential role. The number of errors is frequently used as an important measure to decide about the quality of a software implementation. Therefore, error prediction techniques have been intensively studied in the literature for many years. Despite this, their adoption in practice is still strongly limited to date. In this paper, an...
As the diversity of software status and the uncertainty of software operation, the traditional methods to construct software reliability operational profile are difficult to be applied to reliability testing. This paper introduces an approach to generate operational profile based on scenario. It partitions the usage of software into various paths of software running according to the users and missions...
