I wrote a small Git hook which may be useful in helping OpenStack devs run tests (and any script they like) before a commit is made (see Superuser magazine article).
This way we can save everyone time in the review process by fixing simple issues before they break in the check-pipeline.
Installation is easy (see the GitHub page) and all prompts default to no, so that the dev can easily just hit Enter to skip and continue (but still be reminded).
