`assert False` inside a `try:` raises AssertionError, which the `except
Exception` right below it catches, so several tests reported green no matter
what the code did. `pytest.fail` raises Failed, a BaseException, and escapes.
A bare `a == b` statement is evaluated and discarded. Nine of those sat in
tests, and one was comparing against a model name the router never produces.
Selects B011, B015, B018, PT015, PLR0133 and PLW0127 in ruff-tests.toml
alongside F821, with all 50 existing violations fixed, so no budget file or
ratchet is needed. CI already runs this config over tests/.
* 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
* test(base_llm_unit_tests.py): add test to ensure drop params is respected
* fix(types/prometheus.py): use typing_extensions for python3.8 compatibility
* build: add cherry picked commits
