Test Observability and Monitoring Questions

This topic covers instrumenting testing systems and infrastructure to provide actionable visibility into test health and reliability. Topics include defining and collecting metrics such as pass rate, flakiness, execution time, test latency, resource utilization, and test coverage trends, building dashboards and alerts to detect regressions and infrastructure failures, tracing test failures to underlying services or environment issues, correlating test telemetry with build and deployment events, reducing test waste by identifying flaky or low value tests, and integrating observability into continuous integration and continuous delivery pipelines. Candidates should be able to propose monitoring architectures, meaningful metrics and alerting strategies, and remediation workflows that maintain the value and reliability of automated testing at scale.
