Trace-based test design maps OpenTelemetry traces, logs, and telemetry from real user journeys into actionable tests. You identify production error signals and model trace-based assertions to cover critical microservice paths.

Telemetry-driven prioritization analyzes production traces, logs, and metrics to identify hot paths and coverage gaps. It assesses risk in end-to-end microservice flows to guide which user journeys need tests most.

Yes, trace-based assertions require OpenTelemetry instrumentation in your services. You also need telemetry correlation built into your test infrastructure to map production signals to concrete tests.

Production error analysis extracts real user journey failures from observability platforms to generate, validate, and prioritize tests. This prevents regressions by covering the exact microservice flows that failed in production.

Correlating production logs and metrics with test infrastructure requires OpenTelemetry integration. This maps telemetry signals across microservice flows directly to trace-based assertions, validating real user journeys.

Avoid telemetry-driven test design if your services lack OpenTelemetry instrumentation or if your test infrastructure cannot perform trace correlation. Without production signals, you cannot map real user journeys to concrete tests.
