In recent years, researchers have intensively investigated various topics in test prioritization, which aims to re-order tests to increase the rate of fault detection during regression testing. While the main research focus in test prioritization is on proposing novel prioritization techniques and evaluating on more and larger subject systems, little effort has been put on investigating the threats...
Question-oriented text retrieval, aka natural language-based text retrieval, has been widely used in software engineering. Earlier work has concluded that questions with the same keywords but different interrogatives (such as how, what) should result in different answers. But what is the difference? How to identify the right answers to a question? In this paper, we propose to investigate the "answer...
Like traditional local APIs, web service APIs (web APIs for short) evolve, bringing new and improved functionality as well as incompatibilities. Client programs have to be modified according to these changes in order to use the new APIs. Unlike client programs of a local API, which could continue to use the old API, clients of a web API often do not have the option not to upgrade, since the old version...
Mutation testing has been used to assess and improve the quality of test inputs. Generating test inputs to achieve high mutant-killing ratios is important in mutation testing. However, existing test-generation techniques do not provide effective support for killing mutants in mutation testing. In this paper, we propose a general test-generation approach, called PexMutator, for mutation testing using...
This paper investigates the use of automated testing tools for improving the quality of programs produced by software engineering students. Our approach to software quality assurance utilizes open source, professional software engineering tools to measure a number of quality attributes. Programming assignments are designed and the tools configured to provide timely, formative feedback to students...
Better orderings of test cases can detect faults in less time with fewer resources, and thus make the debugging process earlier and accelerate software delivery. As a result, test case prioritization has become a hot topic in the research of regression testing. With the popularity of using the JUnit testing framework for developing Java software, researchers also paid attention to techniques for prioritizing...
Modern software applications require internationalization to be distributed to different regions of the world. In various situations, many software applications are not internationalized at early stages of development. To internationalize such an existing application, developers need to externalize some hard-coded constant strings to resource files, so that translators can easily translate the application...
Software internationalization is often necessary when distributing software applications to different regions around the world. In many cases, developers often do not internationalize a software application at the beginning of the development stage. To internationalize such an existing application, developers need to externalize some hard-coded constant strings to resource files, so that translators...
