No test reports for this run.

Tell a job where its test runner writes its report and this tab fills in: how many tests passed, failed and were skipped, a bar of the result at a glance, then every failure first — with the assertion that failed and the output around it — over a per-suite list of cases and their durations. No scrolling a log for the word FAIL.

It is one reports: key on the job — a job key, not a step, so the report is collected whatever the job concluded. JUnit XML and go test -json are both understood, and most runners already emit one of them. reports: is a rickub extension and works only in .rickub/workflows/; in .github/workflows/ it is a parse error on purpose, because those files are also meant to run on github.com.
