👍 as is, but are you also going to add usage of diff-quality to jenkins/test.sh?

[sarina]

@cpennington I added diff-quality to the rake task, which works fine for me locally, but doesn't show up in the build coverage report (http://jenkins.edx.org:8080/job/edx-feature-branch-tests/9563/Diff_Coverage_Report/?) - do you know what I need to do for that?

[cpennington]

I don't think this is actually where you want to run these. You probably want to add them to the rake quality task, rather than in the coverage section (since they don't depend on the tests).

@cpennington thanks. I made this into a rake quality task.

Do you know how I could get the HTML reports to show up in Jenkins? Or should I wait for Will to return to configure that?

[sarina]

Moved the task to quality.rake. Put the diff-quality reports into their own reports/ subdirectory, as the reports cover the whole of the platform, not lms/cms/common explicitly.

I tried running this task on a few people's branches, and I had no issue running them. I ran rake pep8; rake pylint; rake quality and everything worked out well with no conflicts.

Still not sure how to make the html reports appear in Jenkins. Thinking about it, I am going to assume this has to be configured explicitly in Jenkins, and I don't have the permissions to configure Jenkins.
