* test(e2e): move live-provider legacy tests into tests/e2e
Port legacy tests that exercise real providers into the tests/e2e suites that own them, using the harness (/model/new plus deferred cleanup) and asserting on what the caller receives. Delete legacy tests already covered at equal or stronger strength by e2e, integration or unit tests, and drop the now empty ocr_testing CircleCI job
* test(e2e): address review on the live-provider test move
Assert the SSE error frame a client actually receives when a post_call guardrail blocks a stream, and require a tool call for every requested city before checking the answer. Restore the OCR matrix and its CircleCI job, the Claude Agent SDK streaming test, and test_async_create_batch, since their SDK-level and callback assertions have no equivalent in tests/e2e
* test(e2e): accept both guardrail block shapes on a blocked stream
A post_call block before the first chunk reaches the client as HTTP 400 with either a JSON error body or a single SSE error frame, depending on whether the block surfaced as an exception or an error chunk. Assert the policy message is present and the blocked output is absent in both
* test(realtime): restore direct SDK realtime tests against OpenAI
The e2e realtime tests go through the proxy and the remaining SDK tests either mock the upstream or assert less, so keep the direct litellm._arealtime tests with and without intent, and TestOpenAIRealtime::test_realtime_connection, in place
* test: make realtime and Nova stream checks deterministic
The direct SDK realtime tests now fail on a refused connection instead of skipping. The with-intent test asserts OpenAI rejects the exact intent value sent, which only happens when the intent is forwarded. The Nova /v1/messages stream test asserts stream structure, stop reason and usage instead of model wording
* test(realtime): own intent forwarding with a unit test instead of a live rejection
Assert litellm._arealtime passes the intent query param into the OpenAI realtime websocket URL, which is the behavior LiteLLM owns, and drop the live test that depended on OpenAI's rejection wording
A name bound twice keeps only the second binding. In `tests/` that is nearly
always a repeated import, harmless but misleading, and the same rule is what
catches the cases that are not harmless: a local that shadows an import the
module still calls, and a second `def test_x` that quietly replaces the first.
311 of the 344 sites were repeated imports and came out with ruff's own fix.
The remaining 33 needed a decision. Four modules imported a name they never
used because a local definition below already shadowed it. Two comprehensions
bound `call` over `unittest.mock.call`, which those modules import and use.
One test rebound the two module handles its nested reload closure had captured.
One class attribute shadowed an unused `status` import.
The load-test fixtures move to a conftest, which is how pytest is meant to share
them, so the test module no longer imports three fixture names it never calls.
The nine `prisma_client` parameters keep a narrow `noqa`: pytest resolves that
fixture by name before the body runs, so the parameter never shadows anything.
