Grafana turns Cypress test results into persistent Prometheus metrics

Grafana Labs published an approach for monitoring Cypress test suites by converting results into Prometheus metrics and shipping them to Grafana Cloud. The pipeline uses Cypress lifecycle hooks, a Prometheus Pushgateway and Grafana Alloy to track failures, durations and flaky tests across runs instead of relying on CI logs alone.

• before:run and after:spec hooks capture test states, pass/fail counts and durations
• Pushgateway holds metrics from short-lived CI jobs until Alloy scrapes them
• GitHub Actions run IDs can be attached to trace metric changes back to CI runs
• Metric publishing failures should not fail an otherwise successful test run
