Contributing¶
Bug reports, issues, feature requests, and other contributions are welcome. If you find a demonstrable problem that is caused by the REANA code, please:
Search for already reported problems.
Check if the issue has been fixed or is still reproducible on the latest
master
branch.Create an issue, ideally with a test case.
If you create a pull request fixing a bug or implementing a feature, you can run the tests to ensure that everything is operating correctly:
$ ./run-tests.sh
Each pull request should preserve or increase code coverage.
