"""Unit tests for OpenClaw adapter env-var key selection and provider URL routing.

The key-selection and URL-routing logic lives inline in OpenClawAdapter.setup()
(adapter.py lines 84-92).  Since setup() carries heavy subprocess dependencies,
these tests isolate the selection logic by reproducing the exact Python expressions
from the adapter source — if the adapter's logic changes, these tests must be kept
in sync.

Organisation:
  TestEnvKeyChain          — priority order of the 3 currently supported keys
  TestProviderUrlMapping   — model-prefix → provider URL dict correctness
  TestNegativeAndFallback  — no keys set / unsupported keys
  xfail stubs              — AISTUDIO + QIANFAN documented as not-yet-implemented
