Microsoft.Testing.Extensions.OpenTelemetry

Microsoft.Testing.Extensions.OpenTelemetry is an extension for Microsoft.Testing.Platform that instruments test execution with OpenTelemetry-compatible traces and metrics.

Microsoft.Testing.Platform is open source. You can find Microsoft.Testing.Extensions.OpenTelemetry code in the microsoft/testfx GitHub repository.

Install the package

dotnet add package Microsoft.Testing.Extensions.OpenTelemetry

About

This package extends Microsoft.Testing.Platform with:

  • OpenTelemetry integration: exposes the Microsoft Testing Platform activity source and meter (both named Microsoft.Testing.Platform) so test execution can be observed via the OpenTelemetry .NET SDK.
  • Lifecycle management: ties the lifetime of a TracerProvider and MeterProvider to the test application, so they are disposed alongside the test host.
  • Observability: lets you route test execution data, via your own OpenTelemetry exporter configuration, into observability backends (e.g. Jaeger, Prometheus, Grafana).
  • Standards-based: leverages the OpenTelemetry .NET SDK so that data is sent only to the telemetry exporters and endpoints that you configure.

Note: AddOpenTelemetryProvider does not register any instrumentation or exporter by default. To actually collect MTP telemetry you must, from the withTracing / withMetrics delegates:

  • call AddTestingPlatformInstrumentation() on both the TracerProviderBuilder and the MeterProviderBuilder to subscribe to the Microsoft Testing Platform source/meter, and
  • register at least one exporter (for example AddOtlpExporter, AddConsoleExporter, or a vendor-specific exporter).

Without instrumentation, no MTP activities or metrics are collected; without an exporter, collected telemetry is not emitted anywhere.
