The release frequency of software projects has increased in recent years. Adopters of so-called rapid release cycles claim that they can deliver addressed issues (i.e., bugs, enhancements, and new features) to users more quickly. However, there is little empirical evidence to support these claims. In fact, in our prior work, we found that code integration phases may introduce delays in rapidly releasing...
The paper presents an approach, namely iHDev, to recommend developers who are most likely to implement incoming change requests. The basic premise of iHDev is that the developers who interacted with the source code relevant to a given change request are most likely to best assist with its resolution. A machine-learning technique is first used to locate source code entities relevant to the textual...
In risk-driven testing, test cases are generated and/or prioritized based on different risk measures. For example, the most basic risk measure would analyze the history of the software and assigns higher risk to the test cases that used to detect bugs in the past. However, in practice, a test case may not be exactly the same as a previously failed test, but quite similar. In this study, we define...
Bug triaging is an important activity in any software development project. It involves developers working through the set of unassigned bugs, determining for each of the bugs whether it represents a new issue that should receive attention, and, if so, assigning it to a developer and a milestone. Current tools provide only minimal support for bug triaging and especially break down when developers must...
While code is typically presented as a flat file to a developer who must change it, this flat file exists within a context that can drastically influence how a developer approaches changing it. While the developer clearly must be careful changing any code, they probably should be yet more careful in changing code that recently saw major changes, is barely covered by test cases, and was the source...
Bug report is becoming a main approach to improve and perfect a complicated piece of software, but analyzing the bug report is a tedious and time-consuming job, especially when the number of bug reports is huge and many duplicate reports are mixed within the incoming bug reports. In this paper, we present a framework to automatically triage and detect the duplicate bug reports by keywords extraction...
Different flavours of recommendation systems have been proposed to help software developers perform software evolution tasks. A number of these recommendation systems are based on changesets. When changeset information is used, recommendations are based on only the end result of the activity undertaken to complete a task. In this paper, we report on an investigation that compared how recommendations...
