计算机软件测试技术与深度开发应用探讨

在非专业软件开发人员对软件开发的过程中会遇到软件设计方法与测试等方面的问题,对软件测试的关键技术以及深度软件开发的方法进行阐述,可以为非专业软件开发人员开发软件提供一定的指导.     

Applying test driven development to embedded software

Test driven development (TDD) is increasing in information technology applications and product development; however, it has not been widely applied in embedded software development. Embedded developers face many challenges. TDD can help overcome some of these challenges, but TDD has to be adapted for embedded systems development. TDD is an important software development practice that can help embedded developers deliver higher quality products. The embedded TDD cycle can help take hardware availability off the software critical path, enabling steady progress with or without hardware. TDD can be used for embedded development in C and C++. Java may also be an option for some embedded systems, and Java is better suited for TDD, as the tools for Java support are much more advanced.     

基于领域特征本体的构件语义描述和组装

构件的功能语义是复用者了解并判断构件可复用性的重要依据，因此必须在构件开发者和复用者共同的知识基础上进行构件描述．目前已有一些方法引入本体作为构件语义描述的基础，但仍然存在语义描述不够精确以及无法支持语义的组装推导等不足．引入了领域分析中提出的基于本体的领域特征模型作为构件语义描述基础，在此基础上给出了构件端口语义、静态语义、语义协议的定义以及语义组装算法．基于构件静态语义和组装算法可以在构件组装时进行语义合成，从而辅助开发者进行基于语义的构件适配和组装分析．

Understanding user privacy expectations: A software developer’s perspective

Software developers are trained to develop and design software applications that provide services to users. However, software applications sometimes collect users’ data without their knowledge. When applications collect and use users’ data without transparency, this leads to user privacy invasions because users do not expect the application to collect and use these information. Therefore, it is important that software developers understand users’ privacy expectations when designing applications in order to handle user data transparently in software applications. However, due to the lack of systematic approaches to extract user privacy requirements, developers end up designing applications either based on their assumptions on user privacy expectations, or relating to their own expectations of privacy as a user. Nevertheless, how accurate these perceived privacy expectations are against actual user expectations is not currently known. This research focuses on investigating developers’ privacy expectations from a user point of view against users’ privacy expectations. We also investigate developers’ assumptions on user privacy expectations against actual user privacy expectations. Our findings revealed that developers’ assumptions on user privacy expectations are close to their own expectations of privacy from a user point of view and that developers’ privacy expectations from a user point of view are significantly different from actual user privacy expectations. With this understanding, we provide recommendations for software developers to understand and acknowledge user expectations on privacy when they design and develop applications.     

On the Eff ects of Exploring Historical Commit Messages for Develop er Recommendation

Many developer recommendation tech-niques have been developed in the literature. Among exist-ing studies, most of them are performed based on exploring the historical commit repository. The thought behind them is that developers who submit similar historical commits relevant to the incoming issue are more probably to be the candidates for the current issue resolution. But whether such a thought is always useful for developer recommen-dation? This paper aims at this problem by conducting a set of empirical studies on four real open-source projects. The results show that, 1) historical commit messages do well reflect the historical experience of the maintenance task of developers and can be used for developer recom-mendation in most of the time; 2) the number of historical commits submitted by the recommended developer(s) and the similarity value used to select the relevant historical commits should be carefully considered to recommend de-velopers for issue resolution; 3) The e?ciency of issue res-olution process can be improved if some associated source code files relevant to this issue can be also recommended;and 4) developer recommendation techniques that rank the recommended developers based on the times of co-changed source code files cannot always produce correct recommen-dation results.

Critics Say Web Services Need a REST

A vocal group of developers critical of the orthodox Web Services stack is touting the use of a technology called REST, or Representational State Transfer Web Services. REST advocates a more streamlined (and familiar) XML-over-HTTP approach for exposing software functionality. Here are some of the issues being debated.     

BAHA: A Novel Approach to Automatic Bug Report Assignment with Topic Modeling and Heterogeneous Network Analysis

We propose an approach called Bug report assignment with topic modeling and heterogeneous network analysis (BAHA) to automatically assign bug reports to developers.Existing studies adopt social network analysis to characterize the collaboration of developers.The networks used in these studies are all homogenous.In real practice of bug resolution,different developers collaborate on different bug reports that makes the homogenous network unable to capture this information.We use heterogeneous network to describe the relations between reporters,bug reports and developers to characterize developers' collaboration.Experiments on Eclipse JDT project show that BAHA outperforms the state of art methods on automatic bug report assignment.
