Abstract
Dynamic compositional symbolic execution is a well-known white-box method for generating unit test data. However there exists certain issues when applying this method for software that heavily depends on floating point data types. In this paper we present these issues and suggest our solution. Our presented method would integrate two techniques: symbolic execution and search-based testing to increase code coverage of software under test. We have implemented it as an extension to tool PEX, that is being developed at Microsoft Research. Our extension implements search-based testing as an optimization technique using AVM method. We present coverage comparison for several benchmark functions.
