Unit tests are valuable as a source of up-to-date documentation as developers continuously changes them to reflect changes in the production code to keep an effective regression suite. Maintaining traceability links between unit tests and classes under test can help developers to comprehend parts of a system. In particular, unit tests show how parts of a system are executed and as such how they are...
Software defects are usually detected by inspection, black-box testing or white-box testing. Current software defect mining work focuses on mining frequent patterns without distinguishing these different kinds of defects, and mining with respect to defect type can only give limited guidance on software development due to overly broad classification of defect type. In this paper, we present four kinds...
GUI test case definition is the core issue in automatic or semi-automatic GUI testing. We use TTCN-3 language to define GUI test cases. The test specifications under this definition are easy to maintain, evaluate and assess. The time related test specifications are covered; few of current works cover this kind of testing. It's easy and flexible to create test oracles by this approach thanks to TTCN-3...
Usability analysis is an important step in software development in order to improve certain aspects of the system. However, it is often a challenge especially when it comes to evaluating applications running on mobile devices because of the restrictions posed by the device and the lack of supporting tools and software available to collect the necessary usability data. This paper proposes a methodology...
Recently there has been a focus on test first and test driven development; several empirical studies have tried to assess the advantage that these methods give over testing after development. The results have been mixed. In this paper we investigate nine teams who tested during coding to examine the effect it had on the external quality of their code. Of the top three performing teams two used a documented...
Employing a software platform is an approach to achieve a higher degree of software reuse since multiple software products can share the platform-provided services. However, the platform development usually involves stakeholders from different application domains. Their application situations vary widely and thus Non-Functional Requirements (NFRs) for the software platforms must address a wider range...
The model-driven approach to software development has not only changed the way software systems are built and maintained but also the way they are tested. For such systems, a model-based testing approach is much recommended since it is aligned with the new model-driven development paradigm that favors models over code with the objective being to reduce time to market while improving product quality...
When Web services play more important roles in software development, the corresponding software dedicated for Web services testing has attracted more attention. This paper proposes a new mutation testing method based on the requirement model presented by OWL-S, which not only improves the test efficiency, but also makes the test work undergoing automatically. How to define the mutant operators, generate...
Testing automation tools enable developers and/or testers to easily automate the entire process of testing in software development. Nevertheless, adopting automated testing is not easy and unsuccessful due to a lack of key information and skills. In order to help solve such problems, we have designed a new framework to support a clear overview of the test design and/or plan for automating tests in...
During the software development process, data that has been gained from the testing phase can help developers to predict software reliability more precisely. But the testing stage usually takes more and more effort due to the growing complexity of software. How to build software that can be tested efficiently has become an important topic in addition to enhancing and developing new testing methods...
Unit testing is an efficient approach to enable high quality in software development. Data preparation and environment establishment costs much in unit testing. In order to achieve efficient collaborative software unit testing, tasks should be scheduled according to their dependence. This paper proposes an extend E-CARGO collaborative model-based method to identify the component to data and component...
Asynchronous javascript and XML (AJAX) is a recent group of technologies used to develop dynamic Web pages. Ajax applications are wisely used nowadays and need to be tested to ensure their reliability. This paper introduces a method and an architecture for automatic AJAX application testing. We use STS automata for describing the application and for generating test cases. We perform an improved random...
In the context of long-term, large-scale, industrial software development, process improvement and measurement to support process improvement is a necessity. Our software projects face the ongoing challenge, ldquoHow can we reduce the number of customer found defects in a cost-effective manner?rdquo This paper describes how the system test team of a large telecommunications company approached this...
Testing has always been an indispensable part of software development. With the increasing amount of testing, the volume of data and information generated from testing grows substantially. The question arises on how to take advantage of the testing data, besides traditional coverage and debugging. In this paper, we propose an approach of using test trace data of a software application to its run-time...
Assessing the quality of tests for BPEL processes is a difficult task in projects following SOA principles. Since insufficient testing can lead to unforeseen defects that can be extremely costly in complex and mission critical environments, this problem needs to be addressed. By using formally defined test metrics that can be evaluated automatically by using an extension to the BPELUnit testing framework,...
Among all the different architectures being researched in the field of multi-agent systems, the mobile agent has shown to be one of the most challenging and most critical systems. With more applications being developed, there is a need to ensure large and complicated mobile agent systems are functioning correctly, with minimum or no errors. Moreover, the model-based testing technique has gained attention...
Manual testing is a laborious and time consuming process. In addition, it may not be effective in finding certain defects. Therefore, we introduce an effective framework for automated testing to help solve such problems. The proposed framework helps automate the distribution, execution, and results analysis of test cases. The workflow of tests and test environments are graphically expressed as tables...
During regression testing, a modified system needs to beretested using the existing test suite. Since test suites may be very large, developers are interested in detecting faults in the system as early as possible. Test prioritization orders test cases for execution to increase potentially the chances of early fault detection during retesting. Code-based test prioritization methods are based on the...
Software diagnosis for finding faults based on the test results is one of the most time-consuming and labor-intensive activities in large scale software development. Revealing the potential knowledge hidden in the test results or program constructs to assist this activity is a rational solution. In this paper, we propose two kinds of debugging applications based on rough set reasoning. One is to select...
A process is an important concept in modern software development. Only when the activities are organized in process descriptions, can these be communicated, followed, observed, and improved. The basis for understanding what testing is, is therefore the understanding of the testing process. This paper presents the general concept of a process, and expands on this to present a suggestion for a generic...
