An open source project typically maintains an open bug repository so that bug reports from all over the world can be gathered. When a new bug report is submitted to the repository, a person, called a triager, examines whether it is a duplicate of an existing bug report. If it is, the triager marks it as DUPLICATE and the bug report is removed from(More)
To facilitate software maintenance and evolution, a helpful step is to locate features concerned in a particular maintenance task. In the literature, both dynamic and interactive approaches have been proposed for feature location. In this article, we present a static and noninteractive method for achieving this objective. The main idea of our approach is to(More)
Test-case prioritization is a typical scenario of regression testing, which plays an important role in software maintenance. With the popularity of Web services, integrating Web services to build service-centric systems (SCSs) has attracted attention of many researchers and practitioners. During regression testing, as SCSs may use up constituent Web(More)
Debugging is a time-consuming task in software development and maintenance. To accelerate this task, several approaches have been proposed to automate fault localization. In particular, testing based fault localization (TBFL), which utilizes the testing information to localize the faults, seem to be very promising. However, the similarity between test cases(More)
In the process of software development and maintenance, software debugging is an inevitable and time-consuming task. To accelerate software debugging, various approaches have been proposed to automate fault localization. Among them, testing-based fault-localization approaches are most promising, which use the execution information of many test cases to(More)
With the popularity of Web Services and Service-Oriented Architecture (SOA), quality assurance of SOA applications, such as testing, has become a research focus. Programs implemented by Business Process Execution Language for Web Services (BPEL), which can compose partner Web Services into activities, are one popular kind of SOA applications. The unique(More)
Testing-based fault-localization (TBFL) approaches often require the availability of high-statement-coverage test suites that sufficiently exercise the areas around the faults. However, in practice, fault localization often starts with a test suite whose quality may not be sufficient to apply TBFL approaches. Recent capture/replay or traditional(More)
Web services technology has received much attention in the last few years, and a lot of research efforts have been devoted to utilizing services on the Internet to fulfill consumers' requirements. However, little research has been done on the current status of web services on the Internet, which has a great impact on current research. Enlightened by this(More)
Software internationalization aims to make software accessible and usable by users all over the world. For a Java application that does not consider internationalization at the beginning of its develop- ment stage, our previous work proposed an approach to locating need-to-translate constant strings in the Java code. However, when being applied on web(More)
