Improvement of a Visualization Technique for the Passage Rate of Unit Testing and Static Checking and Its Evaluation

Software visualization has attracted lots of attention. The techniques fall into two categories: visualization of software component relationships and visualization of software metrics.We have already proposed a hybrid method based on both of the two categories. The proposed method visualizes coincidence between specification and implementation from two aspects: static checking and ordinal testing by test suites. Each of the verification is performed in a method or function basis (unit testing). In the method, each ratio of the coincidence is shown by pie charts which represent classes of the target software. Whole software is represented in a weighted digraph structure.In this paper, we propose Priority Layout to emphasize important classes, and implemented our method into a tool. We have evaluated time in finding bug at source code and test cases between using Priority Layout, ISOM Layout and uncomplicated tables instead of graphs. As a result, time in finding bug at source code and test cases by proposed graph are a half of it using table.
