Observability for QA

16 min · Module 23

Logs, metrics, traces explain failures beyond UI symptoms. During incidents, verify mitigations with dashboards—not only screenshots.

Lab: when status update fails on a buggy release, note environment flags/version in the defect—your “telemetry” analog.

Example / notes

# Defect note example
# release=1.1.0-rc flags include status_update_broken
# symptom: save status returns error banner
