* test: point router/completion/triton tests at the local fake OpenAI endpoint
The shared Railway-hosted mock (exampleopenaiendpoint-production.up.railway.app)
takes down unrelated CI jobs whenever it is unreachable. #30695 moved the mounted
proxy configs onto a job-local fake server but left these in-Python api_base
literals pointing at the dead host, so litellm_router_testing, local_testing_part1,
local_testing_part2 and llm_translation_testing still fail with a 404
"Application not found" when Railway is down
Resolve the api_base from FAKE_OPENAI_API_BASE (default http://127.0.0.1:8190)
through a shared helper, auto-start the canned server from the local_testing and
llm_translation conftests when nothing is already serving, and extend the server
with a Triton embeddings route and a slow-endpoint delay so the triton and
latency-timeout tests run fully offline. The deliberately broken fallback URL is
left as-is so fallback handling still has a failing upstream
* fix: ignore non-loopback FAKE_OPENAI_API_BASE so the local mock is used in CI
* fix: drop 0.0.0.0 from loopback hosts, an unreliable client connect target
* fix(tests): keep fake OpenAI mock alive across xdist workers
ensure_fake_openai_endpoint registered atexit on the worker that spawned
the subprocess, so under -n 4 the first worker to drain its queue would
terminate the shared mock while siblings were still hitting it. Detach
the child via start_new_session and drop the per-worker teardown; reuse
on /health handles re-runs and CI containers clean up themselves
- Router testing: add CircleCI parallelism=4 with timing-based test splitting
- Guardrails testing: add pytest-xdist -n 4, suppress DEBUG logs with LITELLM_LOG=WARNING
- Rewrite conftest.py in both test dirs for xdist compatibility (save/restore pattern)
- Fix module-level Router instances in test_router_fallback_handlers, test_router_custom_routing, test_acooldowns_router
