Abstract
We utilize "Zone Analysis method" to evaluate test quality which analyzes each component (functions, subsystems, etc.) of software. "Zone Analysis method" is evaluating the quality of software products and processes by comparing the size, the number of test cases, and the number of defects of test subjects with "a uniform baseline". However, because the quality of software products and its quality making process depend on the engineer's skill, development environment, etc., there is a limit on this evaluation method only to compare the quality with a uniform baseline. In this paper, we propose an evolved analysis method of test quality to which effect factors of test evaluation targets and quality making processes was considered.
