Test reports should be sent to any endpoints provided in a "Report-To" header, but currently are not. There also don't appear to be WPT that check this behavior.

I should have written "Reporting-Endpoints", not "Report-To".

Actually, I'm wrong! There are existing tests for this behavior: document-reporting-bypass-report-to.https.sub.html document-reporting-named-endpoints.https.sub.html document-reporting-override-endpoint.https.sub.html
Wrong again! Those tests use 'deprecation' and 'document-policy-violation' reports, but don't exercise the test report feature.
