Grafana Turns Cypress Test Results Into Persistent Observability Data

InfoQ Homepage News Grafana Turns Cypress Test Results Into Persistent Observability Data

The approach uses Cypress lifecycle hooks to capture test results, a Prometheus Pushgateway to temporarily hold metrics from the short-lived test jobs, and Grafana Alloy to scrape those metrics and forward them to Grafana Cloud. The resulting data can then be visualised and used for alerting, providing a longer-term view of test-suite behaviour.

Cypress already exposes useful information through its plugin lifecycle. The before:run hook can establish a common identifier for an entire test-suite execution, while after:spec provides the results from each specification, including pass and failure counts, test states, and durations. Grafana's example converts this information into a small set of Prometheus metrics covering individual tests, specifications, and complete runs.
