When we originally open-sourced ManageIQ, the ManageIQ GitHub Repo was integrated with Code Climate. Integrating with Code Climate allowed the developer community to find code with too much complexity and/or duplication and refactor it.
This week, we integrated the ManageIQ GitHub Repo with Travis CI, the continuous integration service. This service runs on each GitHub pull request to ensure that no new code is breaking existing tests (i.e. no regression). If the pull request does cause a regression, the core maintainers of the ManageIQ project will not merge it until this is resolved.
So, keep creating pull requests to make ManageIQ better, but make sure that they do not break any tests!
