Poster: Interactive Coverage Effectiveness Multiplots for Evaluating Prioritized Regression Test Suites

Software testing increases condence in the correctness of an application’s source code. Altering a test suite’s execution order enables earlier detection of defects and allows developers to x errors sooner. The many existing prioritization methods produce different possible test suite orders from which to choose. We propose, implement in a free and open source system, and informally evaluate Interactive Coverage Effectiveness Multiplots, an interactive visualization technique that allows software testers to quickly lter , appraise and compare the effectiveness of many test suite orders. Preliminary results show that researchers, students, and practitioners in the eld of software testing nd the system useful.
