Typical problems of a requirements document, regarding its contents and organization, involve deficient modularization where requirements artifacts may deal with too much information, duplication of requirements, scattering requirements, tangled problems, among other problems. In this paper we describe how to improve requirements documents by removing duplication of information using aspect-oriented refactoring. 相似文献

Security requirements management is especially important in software product lines, given that a weakness in security or a security breach can cause problems throughout all the products of a product line. The main contribution of this work is that of illustrating, by describing part of a real case study, a guided, systematic and intuitive way of dealing with security requirements from the early stages of the product line lifecycle by applying our proposed process of security requirements engineering for software product lines (SREPPLine), which makes it easier the variability and reusability management as well as the traceability relations of the security requirements in the product line. It is based on the use of the latest security requirements techniques, together with the integration of the Common Criteria (ISO/IEC 15408) and ISO/IEC 27001 controls, so that it facilitates the conformance of the product line and its products to the most relevant security standards with regard to the management of security requirements, such as ISO/IEC 27001 and ISO/IEC 15408. 相似文献

面向对象所具有的类、封装、继承、动态连接等特性,使得面向对象测试步骤的划分以及测试策略的选择有别于传统的测试思想.本文针对面向对象软件的特点,采用基于模型的软件测试方法,对UML(United Model Language)设计模型中的顺序图添加OCL(Object Constraints Language)约束,做类间交互的软件测试.本文提出执行图EG生成算法,将顺序图SD转换为执行图EG,解决UML2.0顺序图新增特性中的alt、loop、opt、break四种常见组合片段及其嵌套和多态性问题;为得到最小完备的测试路径,本文提出了EG的遍历策略和测试路径生成算法;最后,根据测试路径确定测试场景,并删除无效场景,生成测试用例.经实验验证,此方法可以基于UML顺序图与OCL约束进行系统地测试. 相似文献

In this paper, we present a technique called Digital Captureless Delay Testing Sensors (DCDTS). This technique allows the
detection of delay faults left uncovered by launch-on-capture transitions due to excessive resources (mainly test time or
tester memory) requirements, with top-off random launch-on-shift patterns that do not require fast switching scan enable signals.
The DCDTS random patterns are internally generated, requiring virtually no additional test application time or tester memory.
As such, DCDTS can be seen as a new way to save both test time and tester memory. Results show that DCDTS can achieve pattern
volume and test time reduction factors of up to 3. When used in complement to existing compression techniques, DCDTS has the
potential to triple their pattern volume (test application time) compression (reduction) rate. Area/performance overhead and
technical obstacles to automation are minimal. An automated sensor selection procedure is proposed, with reasonable CPU time. 相似文献
