Test-driven reuse (TDR) proposes to find reusable source code through the provision of test cases describing the functionality of interest to a developer. Proponents claim that their TDR approaches work well. This paper presents the results of an experiment to evaluate the ability of state-of-the-art TDR tools to locate reusable source code for realistic tasks. We find that non-trivial functionality, like that needed in the daily tasks of developers, can largely not be retrieved by these approaches. We provide an analysis of the shortcomings and underlying problems in the existing approaches, and a discussion of potential solutions.
