The website https://codecov.io is a commerical tool (free for open source, and free to students for closed source through the GitHub Student Developer Pack that provides integrated tools to group, merge, archive, and compare coverage reports.
In CS156, we use codecov.io primarily to:
- You can get a view of Java code coverage through Jacoco and or Pitest
- The value added from codecov is to see those views integrated into one visualization.
- Provide a way for course staff (instructors, TAs, LAs) to see code coverage info for private student repos.
- To provide a way for pair partners and teams to share code coverage info for private student repos.
