摘要： 针对软件测试中功能测试用例集的数量较大且覆盖率较低的问题,提出一种基于支持向量机的测试用例自动生成方法。利用PICT测试工具产生输入参数的两组合或三组合的数据集作为典型样本集,为待测试软件的输入输出关系训练SVM网络功能模型。实验结果表明,训练好的模型可有效地预测出n-way组合的输入数据对应的期望结果,实现自动生成数量较小且覆盖率更高的测试用例集。

摘要： System reliability has become a main concern during the computer-based system design process. It is one of the most important characteristics of the system quality. The continuous increase of the system complexity makes the reliability evaluation extremely costly. Therefore, there is need to develop new methods with less cost and effort. Furthermore, the system is vulnerable to both software and hardware faults. While the software faults are usually introduced by the programmer either at the design or the implementation stage of the software, the hardware faults are caused by physical phenomena affecting the hardware components, such as environmental perturbations, manufacturing defects, and aging-related phenomena. The software faults can only impact the software components. However, the hardware faults can propagate through the different system layers, and affect both the hardware and the software. This paper discusses the differences between the software testing and the software fault injections techniques used for reliability evaluation. We describe the mutation analysis as a method mainly used in software testing. Then, we detail the fault injection as a technique to evaluate the system reliability. Finally, we discuss how to use software mutation analysis in order to evaluate, at software level, the system reliability against hardware faults. The main advantage of this technique is its usability at early design stage of the system, when the instruction set architecture is not available. Experimental results run to evaluate faults occurring the memory show that the proposed approach significantly reduces the complexity of the system reliability evaluation in terms of time and cost.

摘要： Context: Software testing practices and processes in many companies are far from being mature and are usually conducted in ad-hoc fashions. Such immature practices lead to various negative outcomes, e.g., ineffectiveness of testing practices in detecting all the defects, and cost and schedule overruns of testing activities. To conduct test maturity assessment (TMA) and test process improvement (TPI) in a systematic manner, various TMA/TPI models and approaches have been proposed. Objective: It is important to identify the state-of-the-art and the-practice in this area to consolidate the list of all various test maturity models proposed by practitioners and researchers, the drivers of TMA/TPI, the associated challenges and the benefits and results of TMA/TPI. Our article aims to benefit the readers (both practitioners and researchers) by providing the most comprehensive survey of the area, to this date, in assessing and improving the maturity of test processes. Method: To achieve the above objective, we have performed a Multivocal Literature Review (MLR) study to find out what we know about TMA/TPI. A MLR is a form of a Systematic Literature Review (SLR) which includes the grey literature (e.g., blog posts and white papers) in addition to the published (formal) literature (e.g., journal and conference papers). We searched the academic literature using the Google Scholar and the grey literature using the regular Google search engine. Results: Our MLR and its results are based on 181 sources, 51 (29%) of which were grey literature and 130 (71%) were formally published sources. By summarizing what we know about TMA/TPI, our review identified 58 different test maturity models and a large number of sources with varying degrees of empirical evidence on this topic. We also conducted qualitative analysis (coding) to synthesize the drivers, challenges and benefits of TMA/TPI from the primary sources. Conclusion: We show that current maturity models and techniques in TMA/TPI p

摘要： 目前我国的航空事业正处在蓬勃发展的阶段,航空电子系统软件的规模越来越大,系统的复杂度也越来越高。因此,对于航空电子系统软件的验证方法与验证手段的需求也越来越高。在对航空电子系统软件进行仿真验证的过程中,激励器将作为整个仿真验证环境的源头,其数据的正确性和稳定性将直接影响航空电子系统软件的仿真验证结果。传统的激励系统软件往往都是针对某一个或是一些特定型号的航空电子系统而专门进行研制的。这些激励系统软件的通用性极差,复用性极低。在测试时,也无法对激励数据的时序性进行控制。因此,该文针对这两个问题设计了面向航电软件测试的通用激励系统。该通用激励系统仅仅通过配置文件就可以定制出不同种类的激励设备。然后又设计了一套统一的调度框架来对这些激励设备进行时序性控制。
