摘要

变更影响分析(CIA)对软件开发过程至关重要,它可以识别开发过程中变更的潜在影响。需求的变化总是对软件测试产生影响,因为现有测试用例的某些部分可能无法用于测试软件。这影响了新的测试用例完全从软件需求规范的更改版本中生成,这会导致大量的时间和精力来生成新的测试用例来重新测试修改后的系统。因此,本文提出了一种基于需求规范的基于用例变化的测试用例自动影响分析方法。这种方法支持一个框架和CIA算法,当需求规范被更改时,测试用例的影响将被分析。为了检测更改,将比较用例模型的更改前和更改后的两个版本。因此,对代表变量变化原因的模式进行了分类和分析。这将导致对现有测试用例进行分析,看它们是否被完全重用、部分更新以及额外生成。使用等价与分类树相结合的方法自动生成新的测试用例。这有利于测试覆盖的水平,使启用的测试用例数量最小化,并消除冗余的测试用例。通过开发的原型工具演示了该方法的自动化。通过医院信息系统(HIS)的两个真实案例的验证和评估结果,以及实际专家的观点,证实了我们所寻求的这一工具的贡献。

An Automated Impact Analysis Approach for Test Cases based on Changes of Use Case based Requirement Specifications
—Change Impact Analysis (CIA) is essential to the software development process that identifies the potential effects of changes during the development process. The changing of requirements always impacts on the software testing because some parts of the existing test cases may not be used to test the software. This affects new test cases to be entirely generated from the changed version of software requirements specification that causes a considerable amount of time and effort to generate new test cases to re-test the modified system. Therefore, this paper proposes a novel automatic impact analysis approach of test cases based on changes of use case based requirement specification. This approach enables a framework and CIA algorithm where the impact of test cases is analysed when the requirement specification is changed. To detect the change, two versions as before-change and after-change of the use case model are compared. Consequently, the patterns representing the cause of variable changes are classified and analysed. This results in the existing test cases to be analysed whether they are completely reused, partly updated as well as additionally generated. The new test cases are generated automatically by using the Combination of Equivalence and Classification Tree Method (CCTM). This benefits the level of testing coverage with a minimised number of test cases to be enabled and the redundant test cases to be eliminated. The automation of this approach is demonstrated with the developed prototype tool. The validation and evaluation result with two real case studies from Hospital Information System (HIS) together with perspective views of practical specialists confirms the contribution of this tool that we seek.

期刊介绍: IJACSA is a scholarly computer science journal representing the best in research. Its mission is to provide an outlet for quality research to be publicised and published to a global audience. The journal aims to publish papers selected through rigorous double-blind peer review to ensure originality, timeliness, relevance, and readability. In sync with the Journal''s vision "to be a respected publication that publishes peer reviewed research articles, as well as review and survey papers contributed by International community of Authors", we have drawn reviewers and editors from Institutions and Universities across the globe. A double blind peer review process is conducted to ensure that we retain high standards. At IJACSA, we stand strong because we know that global challenges make way for new innovations, new ways and new talent. International Journal of Advanced Computer Science and Applications publishes carefully refereed research, review and survey papers which offer a significant contribution to the computer science literature, and which are of interest to a wide audience. Coverage extends to all main-stream branches of computer science and related applications
