DataTD: A Dataset of Java Projects Including Test Doubles

This dataset contains 1,070 open-source Java projects that include test doubles. The projects were mined from GitHub. The dataset was built by selecting all projects whose primary language is Java and that had at least five stars as of October 29, 2023. This list of projects is available in java_repositories_with_five_stars.txt. The 1,070 projects in this dataset use Maven as their build system, contain JUnit tests, and utilize Mockito to create test doubles. The projects are available in the project.zip archive file. Additionally, the dataset includes metadata about the projects, stored in the projects.json file. This metadata describes the characteristics of each project, along with test double definitions, stubbings, and verifications. Finally, we also provide the source code used to build DataTD, enabling future research on expanding and utilizing the dataset.
