Background: Test quality is a prerequisite for achieving production system quality. While the concept of quality is multidimensional, most of the effort in testing context hasbeen channelled towards measuring test effectiveness. Objective: While effectiveness of tests is certainly important, we aim to identify a core list of testing principles that also address other quality facets of testing, and...
Test prioritization is an effective technique used to reduce the amount of work required to support regression testing in continuous integration development. It aims at finding an optimal order of tests that can detect regressions faster, potentially increasing the frequency of software releases. Prioritization techniques based on test execution history use the results of preceding executions to determine...
Independent testing in the enterprise is largely a manual activity with manual test design and manual creation of test scripts. Enterprises often outsource independent testing to third party service providers. During knowledge transition, the service provider test team has to understand the IT system functionality and the test scripts which can be non-trivial as currency of documents could be a challenge...
The main focus of Software Engineering discipline is to establishing methods and processes for the effective and efficient development of software projects. One of the most relevant paradigms for achieving this goal is Model-Driven Development (MDD). MDD uses models at different abstraction levels to automatically generate software products by means of model-transformations. However, one of the main...
Agile processes emphasize iterative delivery rather than assuming the definition of all detailed requirements and architecture up front. This "just enough" approach generally considers user stories and acceptance tests as sufficient documentation for successful system development. However, industry practices have shown that this minimalism is appropriate for projects with short duration...
Wide-spread adoption of the agile movement has rapidly changed the landscape of software industry. In particular, Scrum is an agile process framework that has become extremely popular in industry. However, the practical implementation of Scrum in companies rarely follows the text book ideals. Typically, companies deviate from the proposed Scrum practices for different reasons. While some deviations...
This paper describes the replication of an empirical study comparing tool-supported test case generation and manual development of unit tests. As variation to the original study, which was based on test results from students performing manual unit testing for 60 minutes, the replication involves professional software developers with several years of industry experience and extends the initial time...
Different kinds of process model are prescribed for software organizations, and each offers successful project outcomes if followed. There is little evidence that organizations strictly adhere to specific models. We surveyed 195 participants from 51 New Zealand (NZ) software organizations with a view to increasing our understanding of practice implementation in NZ. We found that practices are implemented...
The advantage of combinatorial techniques over less structured approaches is supported by the experience from numerous real-world projects where a significant reduction of the number of test cases has been achieved without compromising functional coverage. However, to fully benefit from combinatorial testing, the applied techniques and tools have to satisfy the requirements and needs of testers and...
Test Design -- how test specifications and test cases are created -- inherently determines the success of testing. However, test design techniques are not always properly applied, leading to poor testing. We have developed an analysis method based on identifying mistakes made when designing the test cases. Using an extended test case template and an expert review, the method provides a systematic...
Context: Software product lines (SPL) are used in industry to achieve more efficient software development. To test a SPL is complex and costly and often becomes a bottleneck in the product line organization. Objective: This research aims to develop and evaluate strategies for improving system test selection in a SPL. Method: Initially industrial practices and research in both SPL testing and traditional...
Over the past few years, various new service development tools and techniques have been developed. However, little is known regarding the factors influencing their adoption. The objective of this paper is to build a theoretical framework to explain the determinants of adopting NSD tools in service firms. We do so by using the theory of planned behavior (TPB) to explain the adoption behavior. TPB has...
This paper is a report on how sustainable and fruitful cooperation was achieved between a small university department and an industry partner. It outlines the range and type of activities that need tube undertaken over a longer than normal duration. It also describes the expectations from the industry partner for the cooperation to be successful.
