# opentelemetry-test-utils — Test utilities for OpenTelemetry unit tests

License: permissive · Maintenance: active · Downloads: 651.2K/mo

## What it is and what it does

OpenTelemetry Test Utils is a support package within the OpenTelemetry Python project that supplies test utilities and fixtures for writing unit tests. It is designed to help developers test OpenTelemetry instrumentation and SDK code by providing reusable testing helpers. The package depends on opentelemetry-api, opentelemetry-sdk, asgiref, and requests, making it part of the broader OpenTelemetry ecosystem.

This is a Beta-status package (Development Status :: 4 - Beta) that supports Python 3.10 through 3.14. It is maintained by the OpenTelemetry community and receives regular updates. The package is not intended as a standalone tool but rather as a dependency for projects that need to test their own OpenTelemetry instrumentation code.

Use it for:

- Writing unit tests for custom OpenTelemetry instrumentation packages
- Testing OpenTelemetry SDK extensions and exporters
- Validating trace and metric collection in your instrumented application code
- Setting up test fixtures for telemetry-related test suites

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides test utilities and helpers for writing unit tests for OpenTelemetry instrumentation and SDK code.

Yes, if you are developing OpenTelemetry instrumentation or testing SDK code. Install it as a test dependency (dev/test requirements) in projects that need to validate their own telemetry logic. Not needed for applications that only consume OpenTelemetry instrumentation.

## Install

pip install opentelemetry-test-utils
uv add opentelemetry-test-utils
poetry add opentelemetry-test-utils

## Installing opentelemetry-test-utils

Before you install: Low install friction with a pure-Python wheel. Actively maintained as part of the OpenTelemetry project with a recent release (29 days ago) and active repository status.

License in practice: Licensed under Apache-2.0 (permissive), which allows free use, modification, and distribution with minimal restrictions.

Quickstart:

pip install opentelemetry-test-utils

from opentelemetry_test_utils import ...
# Use test utilities in your test suite
