The OpenNMS project uses Atlassian's JIRA project management platform. We thank Atlassian for providing a no-cost license to the project.
The source code is managed by git and is hosted on GitHub. We also use a pull request driven approach to submit patches for bug fixes or enhancements.
The software is covered by a large test suite. For running test suits and build packages for deployment we use Atlassian Bamboo.
