Run the arthur-observability-sdk unit tests. Use when you want to verify SDK logic without building a wheel or spinning up external services.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Run Unit Tests Unit tests cover `Arthur` initialization, env-var resolution, prompt management, context helpers, and telemetry setup. They run entirely in-process — no wheel build, no network calls. ## Prerequisites `python/src/arthur_genai_client/` must exist (it is gitignored). If missing: ```bash ./scripts/generate_openapi_client.sh generate python ./scripts/generate_openapi_client.sh install python ``` ## Run all unit tests From the `arthur-observability-sdk/python/` directory: ```bash uv run pytest tests -m unit_tests -v ``` ## Run a specific test file or test ```bash uv run pytest tests/test_client.py -v uv run pytest tests/test_client.py::test_arthur_requires_task_or_service_name -v ``` ## Run with keyword filter ```bash uv run pytest tests -m unit_tests -k "env" -v ``` ## Notes - Unit tests are marked with `@pytest.mark.unit_tests` (via `pytestmark` at the module level). - They mock at the `OTLPSpanExporter` boundary or use `InMemorySpanExporter` — no real OTLP endpoint needed. - If tests import `arthur_genai_client` and fail with `ModuleNotFoundError`, the generated client is missing (`python/src/arthur_genai_client/`). Run the generate-client skill first.

How to install
mdr add arthur-ai/arthur-engine/test-unit@sha256:47c981cef713eb20The line at the top of this page pins the label git:20260407.50741a3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
