摘要: A large and complex software system could contain a number of bugs. It is desirable for developers to understand how these bugs are distributed across the system, so they have better overview quality. In this paper, we describe BugMap, tool developed visualizing large-scale bug location information. Taken source code data as input, BugMap can display localizations on topographic map. By examining map, components files affected by We apply visualize distribution Eclipse components/files. The results show that our effective understanding overall quality status identifying problematic areas system.
