Overview Although researchers have developed several ways to reason about the location of faults in spreadsheets, no single form of reasoning is without limitations. Multiple types of errors can appear in spreadsheets, and various fault localization techniques differ in the kinds of errors that they are effective in locating. Because end users who debug spreadsheets consistently follow the advice of fault localization systems, it is important to ensure that fault localization feedback corresponds as closely as possible to where the faults actually appear. This paper describes an emerging system that attempts to improve fault localization for end-user programmers by sharing the results of the reasoning systems found in WYSIWYT (What You See Is What You Test) and UCheck.
