@Jdlrobson Is there a code coverage GUI somewhere to check out the front end coverage in detail? I found https://doc.wikimedia.org/cover-extensions/PageTriage/ but I think that's PHP only. Thanks for your work on this ticket.
I don't believe it's published anywhere right now but it can be.
If you run npm run jest it will create coverage/lcov-report/index.html
which you can open in your browser.
I think if you change the output directory to docs, and also add it to the npm run doc command it should appear magically at docs.wikimedia.org
Edit: You can use https://jestjs.io/docs/cli#--coveragedirectorypath to output coverage to the docs folder.
If you do something like this patch to Popups you should be able to get the JS coverage report in SonarQube at https://sonarcloud.io/component_measures?id=mediawiki-extensions-PageTriage&metric=new_coverage&view=list
