T-Evos: A Large-Scale Longitudinal Study on CI Test Execution and Coverage Evolution

<strong>Description</strong> T-Evos is a dataset on test results and coverage evolution, covering 6,495 consecutive commits across 12 open-source Java projects. <strong>Version 0.1.0</strong> We have included the test results and code coverage data. The test results data has been combined into the `test_status.json` for ease of access at the root level of the repository. Each of the node zip files contains the code coverage data. In each of the zip files, the code coverage data folder is structured as followed: project_name commit_id details test_name.json (individual test coverage data) ... coverage.json (full test coverage data on commit_id) surefire_test_method_dict.json (available test cases) project_name.csv (commit build status [success/fail]) Note: the current version of the dataset includes temporary `project_cluster` folders that users might kindly ignore.
