"""Suite-wide test configuration.

``otel_sdk`` marks a test that needs the OpenTelemetry SDK (the ``opentelemetry``
extra), not just the API that ``mcp`` pulls in. Under CI a missing SDK fails the
test: the core jobs install the extra, so its absence is a broken install, and a
skip there would report a tracing contract as green without running it. Locally
it skips with the install hint, so a ``.[dev]`` checkout still runs the suite.
