Center node: "investigating the potential of test driven development for spreadsheet engineering"
  Abstract: It is widely documented that the absence of a structured approach to spreadsheet engineering is a key factor in the high level of spreadsheet errors. In this paper we propose and investigate the application of Test-Driven Development to the creation of spreadsheets. Test-Driven Development is an emerging development technique in software engineering that has been shown to result in better quality software code. It has also been shown that this code requires less testing and is easier to maintain. Through a pair of case studies we demonstrate that Test-Driven Development can be applied to the development of spreadsheets. We present the detail of these studies preceded by a clear explanation of the technique and its application to spreadsheet engineering. A supporting tool under development by the authors is also documented along with proposed research to determine the effectiveness of the methodology and the associated tool.
