Abstract
Software testing is conducted to verify whether the software satisfies its specifications derived from requirements. However, when the numbers of requirements and test cases increase, it is difficult to grasp how many requirements are tested. In this paper, we propose a requirements coverage visualization process. The process uses document similarities to find traceability links and provides two views for comprehensively and precisely grasping the coverage. Experimental results demonstrate that the visualization process provides beneficial views to analyze which requirements are tested or not tested.
