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:

./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:

uv run pytest tests -m unit_tests -v

Run a specific test file or test

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

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.
