There are several studies related to Test Driven Development (TDD), but many with certain divergences of results due to the short time to perform the experiments. Moreover, the environ- ment where they are carried out which is generally academic. On the other hand, the environment requiring tools not used by practitioners or imposing many technical and training requirements for their applica- tion. Goal: Our goal is to provide a tool that supports the evaluation of the TDD process in the software industry and academia settings. The tool is focused on analyzing the effects of verification, validation and test (VV&T). In addition, we evaluated the compliance of TDD usage in soft- ware development. Method: In this study we used the Goal Question Metric (GQM) paradigm to characterize a set of objectives using metrics towards TDD effects on software quality. We conducted a case study with IT professionals to evaluate the tool developed. Results: Consi- dering the existing tools that perform TDD compliance assessment, we developed a Butterfly tool to enable the evaluation of the TDD lifecy- cle as the developer performs the coding of the software. With this tool it is possible to analyze the compliance of TDD usage during software development. Conclusions: The tool allows to measure the effects of TDD when developing software, which will support in the characteriza- tion of TDD contributions and interventions applied to software quality in future works.
