Research And Implementation Of Reuse Method For Component Test Case

With the development of software technology, the complexity of software products is increased, resulting in a wide variety of software malfunctions and causing varying degrees of loss, which makes the quality of software products a hot issue in both domestic and overseas software industry. Therefore, it has become the scientists' target to construct software products with high quality and reliability.It has been found that software reuse is an important technical means to improve the quality of software products after many years research. Software reuse is an important solution to avoid work duplication, lower production costs, reduce error introduction, and shorten development cycle. Software reuse and development based on the component is considered as the most effective way to improve software productivity and quality, and system flexibility and standardization, which achieve fast software development, bring huge economic benefits. The reuse based on the component test case is the core part of the component testing, also a practical method of software reuse.This dissertation takes the component test case reuse as object, establishes the model of component test case, and offers the unified form of test case as well as studies the retrieval mechanism including word segmentation, indexing techniques and matching techniques which will have impact on the efficiency of component test case reuse. By improving the present techniques of word segmentation, it will be more suitable for the specific field of the component test case reuse, and the tree graph of users'demand will be produced by indexing the sub-word. This dissertation proposes a matching calculation method by analyzing and improving the present matching calculation method. The output is provided to the user'by sorting the information of component test case, and also, kinds of editing functions use case, including the sub-tree, node, add records, modify, and delete operations, are also provided three reuse method including copy reuse, evolution reuse and creation reuse for the user.Finally, a prototype tool of component test case reuse is realized, and it is proved to be helpful for stimulating the efficiency of component test case reuse by the research on the matching calculation method of this dissertation.
