A Comparative Study on Results of Design Patterns Recovery Tools

Over the last one and half decade a large number of design pattern recovery techniques and tools are presented for recovering patterns from source code of legacy applications. The results presented and published by different tools are very diverse, susceptible and debatable. It is really very difficult for community to select an existing design pattern recovery tool for purpose of recovering patterns due to reliability of their results. There is an apparent need to evaluate and compare results of these tools and explore key factors which cause wide disparity in the results. We present the comparative analysis on selected tools based on results rendered by different design pattern recovery tools. The common results extracted by different tools after manual verification will become benchmark for future.
