Abstract

This research presents PyPseudo, a novel Python implementation of pseudo-tested code detection that combines Extreme Mutation Testing (XMT) and Statement Deletion (SDL) techniques. While traditional code coverage metrics provide a false sense of security by only indicating which code is executed by tests, pseudo-tested code represents a critical gap in software quality assurance where code can be modified or removed without causing test failures. The implementation addresses this challenge by adapting proven mutation testing approaches from the Java ecosystem to Python’s dynamic environment, while introducing novel solutions for Python-specific challenges such as dynamic typing and runtime behavior.
