Debugging mobile phone applications is hard, as current debugging techniques either require multiple computing devices or do not support graphical debugging. To address this problem we present GROPG, the first graphical on-phone debugger. We implement GROPG for Android and perform a preliminary evaluation on third-party applications. Our experiments suggest that GROPG can lower the overall debugging time of a comparable text-based on-phone debugger by up to 2/3.

This paper presents ConfDiagnoser, an automated configuration error diagnosis tool for Java software. Conf-Diagnoser identifies the root cause of a configuration error - a single configuration option that can be changed to produce desired behavior. It uses static analysis, dynamic profiling, and statistical analysis to link the undesired behavior to specific configuration options. ConfDiagnoser differs from existing approaches in two key aspects: it does not require users to provide a testing oracle (to check whether the software functions correctly) and thus is fully-automated; and it can diagnose both crashing and non-crashing errors. We demonstrated ConfDiagnoser's accuracy and speed on 5 non-crashing configuration errors and 9 crashing configuration errors from 5 configurable software systems.

We focus on functional testing of enterprise applications with the goal of exercising an application's interesting behaviors by driving it from its user interface. The difficulty in doing this is focusing on the interesting behaviors among an unbounded number of behaviors. We present a new technique for automatically generating tests that drive a web-based application along interesting behaviors, where the interesting behavior is specified in the form of “business rules.” Business rules are a general mechanism for describing business logic, access control, or even navigational properties of an application's GUI. Our technique is black box, in that it does not analyze the application's server-side implementation, but relies on directed crawling via the application's GUI. To handle the unbounded number of GUI states, the technique includes two phases. Phase 1 creates an abstract state-transition diagram using a relaxed notion of equivalence of GUI states without considering rules. Next, Phase 2 identifies rule-relevant abstract paths and refines those paths using a stricter notion of state equivalence. Our technique can be much more effective at covering business rules than an undirected technique, developed as an enhancement of an existing test-generation technique. Our experiments showed that the former was able to cover 92% of the rules, compared to 52% of the rules covered by the latter.

The literature reports that source code lexicon plays a paramount role in program comprehension, especially when software documentation is scarce, outdated or simply not available. In source code, a significant proportion of vocabulary can be either acronyms and-or abbreviations or concatenation of terms that can not be identified using consistent mechanisms such as naming conventions. It is, therefore, essential to disambiguate concepts conveyed by identifiers to support program comprehension and reap the full benefit of Information Retrieval-based techniques (e.g., feature location and traceability) whose linguistic information (i.e., source code identifiers and comments) used across all software artifacts (e.g., requirements, design, change requests, tests, and source code) must be consistent. To this aim, we propose source code vocabulary normalization approaches that exploit contextual information to align the vocabulary found in the source code with that found in other software artifacts. We were inspired in the choice of context levels by prior works and by our findings. Normalization consists of two tasks: splitting and expansion of source code identifiers. We also investigate the effect of source code vocabulary normalization approaches on software maintenance tasks. Results of our evaluation show that our contextual-aware techniques are accurate and efficient in terms of computation time than state of the art alternatives. In addition, our findings reveal that feature location techniques can benefit from vocabulary normalization when no dynamic information is available.

In this paper we describe distributed Scrum augmented with best practices in global software engineering (GSE) as an important paradigm for teaching critical competencies in GSE. We report on a globally distributed project course between the University of Victoria, Canada and Aalto University, Finland. The project-driven course involved 16 students in Canada and 9 students in Finland, divided into three cross-site Scrum teams working on a single large project. To assess learning of GSE competencies we employed a mixed-method approach including 13 post-course interviews, pre-, post-course and iteration questionnaires, observations, recordings of Daily Scrums as well as collection of project asynchronous communication data. Our analysis indicates that the Scrum method, along with supporting collaboration practices and tools, supports the learning of important GSE competencies, such as distributed communication and teamwork, building and maintaining trust, using appropriate collaboration tools, and inter-cultural collaboration.

Communities of developers have rapidly become global, encompassing multiple timezones and cultures alike. In previous work we investigated the possible shapes of communities for software development. In addition, we explored mechanisms to uncover communities emerging during development. However, we barely scratched the surface. We found that development communities yield properties of dynamic change and organic evolution. Much work is still needed to support such communities with mechanisms able to proactively react to community dynamism. We argue that service-networks can be used to deliver this support. Service-networks are sets of people and information brought together by the internet. This paper is a first attempt at studying this research area by means of a real-life case-study in a large global software development organisation.

Feature location is a human-oriented and information-intensive process. When performing feature location tasks with existing tools, developers often feel it difficult to formulate an accurate feature query (e.g., keywords) and determine the relevance of returned results. In this paper, we propose a feature location approach that supports multi-faceted interactive program exploration. Our approach automatically extracts and mines multiple syntactic and semantic facets from candidate program elements. Furthermore, it allows developers to interactively group, sort, and filter feature location results in a centralized, multi-faceted, and intelligent search User Interface (UI). We have implemented our approach as a web-based tool MFIE and conducted an experimental study. The results show that the developers using MFIE can accomplish their feature location tasks 32% faster and the quality of their feature location results (in terms of F-measure) is 51% higher than that of the developers using regular Eclipse IDE.

Using software metrics to keep track of the progress and quality of products and processes is a common practice in industry. Additionally, designing, validating and improving metrics is an important research area. Although using software metrics can help in reaching goals, the effects of using metrics incorrectly can be devastating. In this tutorial we leverage 10 years of metrics-based risk assessment experience to illustrate the benefits of software metrics, discuss different types of metrics and explain typical usage scenario's. Additionally, we explore various ways in which metrics can be interpreted using examples solicited from participants and practical assignments based on industry cases. During this process we will present the four common pitfalls of using software metrics. In particular, we explain why metrics should be placed in a context in order to maximize their benefits. A methodology based on benchmarking to provide such a context is discussed and illustrated by a model designed to quantify the technical quality of a software system. Examples of applying this model in industry are given and challenges involved in interpreting such a model are discussed. This tutorial provides an in-depth overview of the benefits and challenges involved in applying software metrics. At the end you will have all the information you need to use, develop and evaluate metrics constructively.

Mentoring project newcomers is a crucial activity in software projects, and requires to identify people having good communication and teaching skills, other than high expertise on specific technical topics. In this demo we present Yoda (Young and newcOmer Developer Assistant), an Eclipse plugin that identifies and recommends mentors for newcomers joining a software project. Yoda mines developers' communication (e.g., mailing lists) and project versioning systems to identify mentors using an approach inspired to what ArnetMiner does when mining advisor/student relations. Then, it recommends appropriate mentors based on the specific expertise required by the newcomer. The demo shows Yoda in action, illustrating how the tool is able to identify and visualize mentoring relations in a project, and suggest appropriate mentors for a developer who is going to work on certain source code files, or on a given topic. Demo URL: http://youtu.be/4yrbYT-LAXA.
在软件项目中，指导项目新人是一项至关重要的活动，并且需要识别具有良好沟通和教学技能的人，而不是具有特定技术主题的高专业知识的人。在这个演示中，我们展示了Yoda (Young and newcOmer Developer Assistant)，这是一个Eclipse插件，可以为加入软件项目的新人识别和推荐导师。Yoda挖掘开发人员的沟通(例如，邮件列表)和项目版本控制系统来识别导师，使用的方法受到了ArnetMiner在挖掘导师/学生关系时所做的启发。然后，它根据新人所需的具体专业知识推荐合适的导师。演示展示了Yoda的工作，说明了该工具如何能够识别和可视化项目中的指导关系，并为将要处理特定源代码文件或给定主题的开发人员建议适当的指导。演示URL: http://youtu.be/4yrbYT-LAXA。

Peer code review is a cost-effective software defect detection technique. Tool assisted code review is a form of peer code review, which can improve both quality and quantity of reviews. However, there is a significant amount of human effort involved even in tool based code reviews. Using static analysis tools, it is possible to reduce the human effort by automating the checks for coding standard violations and common defect patterns. Towards this goal, we propose a tool called Review Bot for the integration of automatic static analysis with the code review process. Review Bot uses output of multiple static analysis tools to publish reviews automatically. Through a user study, we show that integrating static analysis tools with code review process can improve the quality of code review. The developer feedback for a subset of comments from automatic reviews shows that the developers agree to fix 93% of all the automatically generated comments. There is only 14.71% of all the accepted comments which need improvements in terms of priority, comment message, etc. Another problem with tool assisted code review is the assignment of appropriate reviewers. Review Bot solves this problem by generating reviewer recommendations based on change history of source code lines. Our experimental results show that the recommendation accuracy is in the range of 60%-92%, which is significantly better than a comparable method based on file change history.
