DataTD: A Dataset of Java Projects Including Test Doubles

This dataset contains 1,070 open-source Java projects including test doubles. The projects were mined from GitHub. The starting point for building the dataset included all projects whose main language is Java and that had at least five stars as of October 29, 2023. This set of projects is listed in java_repositories_with_five_stars.txt. The 1,070 projects comprising this dataset use Maven as their build system, containing JUnit tests, and use Mockito to create test doubles. The projects are available in the project.zip archive file. The dataset also contains metadata about the projects, which is available in the projects.json file. The metadata describes the characteristics of each project together with the test double definitions, stubbings, and verifications inside the project. Finally, we also make available the source code used to build DataTD for future research on using and extending the dataset.
