Test Metrics and Continuous Improvement Questions

Define the key automation metrics to collect and how to analyze test results to drive continuous improvement. Topics include pass and fail rates, test execution time and variance, flakiness or nondeterministic failure rates, coverage by feature and by test type, defect detection effectiveness, and cost and return on investment indicators. Explain instrumentation of test runs, building dashboards and alerts, trending and baseline detection, root cause analysis for unstable suites, prioritization for test stabilization or removal, and feedback loops with development and product teams to continuously improve tests and product quality.
