Improvement on ABDOM-Qd and Its Application in Open-Source Community Software Defect Discovery Process
Zhi-Tao He, Haihua Yan, Chao Liu · 2013
ABDOM-Qdis a model to describe the characteristics of software defect discovery time-ordered process, such as periodicity, attenuation, oscillation, incremental and discrete. It can help testing participants to evaluate testing quality and to predict testing process with the time-ordered software defect discovery amounts in a good organized software testing process. Due to the poor organization in open-source software community, software defect discovery data show their obvious uncertainties such as mutations and randomness. In the early study of ABDOM/ABDOM-Qdthis kind of process was excluded from the discussion. So it becomes an issue that whether ABDOM-Qdmodel can be applied to open-source community software defect discovery process and reveal new natures and characteristics. In order to answer the question, the normalization of b in ABDOM-Qdwere discussed firstly under the curves paradigms and theirs actual significances discussion in conditions b×τ >0 and b×τdwith stronger describing capability was established. Then ABDOM-QBdwas applied in a NASA's open-source project, which is a typical representative of open-source projects, to fit the software defect data and a good fitting result was obtained. Finally with the application results the model's applicability and the characteristics of open-source community software defects discovery process were preliminarily discussed.
