Do I need to instrument my application code?

While the reporter works for test metrics alone, full trace correlation requires your backend services to be instrumented with OpenTelemetry to propagate the trace context.

What is trace-based testing in this context?

Trace-based testing allows you to use Tracetest to assert on backend spans triggered by your Playwright actions, ensuring that specific API calls or database operations occurred as expected.

How does this skill help debug flaky tests?

By correlating UI test failures with backend traces and logs, you can pinpoint exactly which service or database query failed, helping distinguish between flaky test code and environmental backend issues.

Does this work with cloud-based observability stacks?

Yes, it includes configurations for local setups as well as cloud-native environments like Railway using standard OTLP exporters and environment variables.

분석 및 모니터링

Integrates Playwright end-to-end tests with OpenTelemetry and Grafana to provide full-stack trace correlation and performance metrics.

소개

The Playwright Test Observability skill bridges the gap between frontend testing and backend monitoring by connecting your test suite to an OpenTelemetry-compatible stack including Grafana, Prometheus, Loki, and Tempo. This enables developers to visualize the entire request lifecycle—from a browser click through the backend services to the database—within a single trace. It is particularly useful for debugging intermittent failures in distributed systems, monitoring test suite performance over time, and performing trace-based assertions to validate backend side-effects during UI interactions.
