MILU: A Customizable, Runtime-Optimized Higher Order Mutation Testing Tool for the Full C Language

Abstract

This paper introduces MILU, a C mutation testing tool designed for both first order and higher order mutation testing. All previous mutation testing tools apply all possible mutation operators to the program under test. By contrast, MILU allows customization of the set of mutation operators to be applied. To reduce runtime cost, MILU uses a novel 'test harness' technique to embed mutants and their associated test sets into a single-invocation procedure.
