Ah, that makes sense. The e2e tests are indeed using 3030 https://github.com/apache/jena/blob/748fc2d0c2b3e397bd2571a29c71106f840505ae/jena-fuseki2/jena-fuseki-ui/src/services/mock/json-server.js#L18
If I recall correctly, there is a way to configure it so the port is dynamic. And I'd be OK with the e2e tests being executed only in CI or in a different maven profile. Cypress requires a few GB's of dependencies/tools too. I believe most contributors would prefer to avoid downloading that if it is not necessary for their changes.
