InPreSS: A Slicing-based Tool for Regression Analysis

Numerous program-slicing approaches aim at helping developers troubleshoot regression failures. The main idea behind these approaches is to identify a subset of interdependent program statements relevant to the failure, minimizing the amount of code developers need to inspect. The accuracy and reduction rate achieved by these techniques are key considerations toward their applicability in practice: inspecting only the statements identified in the slice should be faster and more efficient than inspecting the code in full. This paper proposes a novel approach, implemented in a tool named InPreSS, for reducing the size of a slice by accurately identifying and summarizing the propagation-related code blocks.
