Violations will cause a build to be marked as failed due to build configuration problems - for example if the coverage.py HTML path is empty or incorrect, the build will inaccurately be reported as failing and spam innocent committers. It should be marked as aborted or some other state indicating that the tests actually passed but there was something wrong within the Jenkins environment.

ERROR: failed to find coverage HTML reports
Build step 'Publish coverage.py HTML reports' changed build result to FAILURE
