This repository includes data and scripts from the paper Do Open Source Projects Deliver Pull Requests Faster Using CI? A Conceptual Replication Study
This study collected data from many GitHub open source projects, empirically investigated whether Continues Integration (CI) affects the delivery rate of Pull Requests (PR).
File RQ1.ipynb analyzed metadata from pull_requests_meta_data.csv and releases_meta_data.csv.
RQ2.1.Rmd and RQ2.2.Rmd analyzed the two questions of RQ2 in the paper respectively. Tabular data in pull_requests_csv.rar and pull_requests_raw_csv.rar were used.
RQ3.ipynb analyzed 54 new projects with CI adopted and 28 projects that never adopted CI. RQ3_projects_info.csv lists the created time and whether it has adopted CI of each 82 projects. csv files with -ci at the end are dataset of projects with CI. csv files with -nci at the end are datasets of projects without CI.
