This document provides an overview of software fault detection and prevention mechanisms. It discusses several fault detection mechanisms used in the software development lifecycle, including automated static analysis, graph mining, and classifiers. Automated static analysis tools can find standard problems but miss many faults that could lead to failures. Graph mining uses call graph analysis to identify issues in function calling frequencies or structures. Classifiers like NaiveBayes can be trained on normal code behavior to identify abnormal events. The document also discusses fault prevention benefits, related work, and concludes with the importance of fault detection and prevention for developing high quality, reliable software.
