This research involves a methodology and associated proof of concept tool to partially automate software validation by comparing UML use cases with particular execution scenarios in source code. These execution scenarios are represented as the internal documentation (identifier names and comments) associated with sequences of execution in static call graphs. This methodology has the potential to reduce validation time and associated costs in many organizations, by enabling quick and easy validation of software relative to the use cases that describe the requirements. The proof of concept tool as it currently stands is intended as an aid to an IV&V software engineer, to assist in directing the software validation process. The approach is lightweight and easily implemented.
