* test: drop the cwd-relative sys.path.insert calls from the test suite
TQ003 stands at 1,077 across 1,058 files, and 1,015 of them are the same shape:
sys.path.insert(0, os.path.abspath("../..")) and its deeper siblings. The
argument resolves against the working directory rather than the file, so from
the repo root, where every job runs pytest, it inserts the directory two levels
above the checkout. It has never pointed at litellm. The package is installed
into the environment anyway, which is what actually makes the import work, and
what the rule's message has said all along.
Removing them leaves 1,634 imports of sys and os with no remaining reference,
and those go too, except where another test module imports the name back out of
the file. The rest of TQ003 is 62 call sites that resolve against __file__ or a
variable, which are a different question and are left alone.
Collection is identical either way: 45,871 tests and the same 51 pre-existing
collection errors before and after, and ruff reports no new undefined name.
* test: drop the duplicate imports the sys.path sweep exposed to F811
* test(pre-call-utils): restore the os import the new bedrock tests need
Twenty-three tests across eleven files opened with litellm.set_verbose = True
and never put it back, so the flag stayed on for everything that ran after them
in the same process. None of those files read the output it produces: no
caplog, no capsys, no assertion on a log line, so the flag was left over from
debugging. Deleting it beats restoring it, since restoring keeps the noise.
Ten of the eleven stop leaving the flag on. test_volcengine_embedding.py still
ends with it set, from something it exercises rather than from the test itself,
which is worth its own look.
ruff.toml excludes tests/* from `ruff check`, so nothing has ever checked the
test tree for names that do not exist. That matters more in tests than in
product code: a NameError inside a test whose body is wrapped in
`except Exception: pass` is swallowed, and the test reports green forever.
Adds ruff-tests.toml selecting F821 alone, wired into the lint workflow and
`make lint-ruff`, and clears every existing violation:
- 4 tests interpolated an unbound `e` into a `pytest.fail` message reached only
on the failure path, so the NameError, not the assertion, is what ran.
test_llm_guard_error_raising is the worst: it passes today with content
safety disabled entirely. It now asserts the 400 and its detail body.
- 5 sites construct BaseExceptionGroup, a 3.11 builtin, in a tree that still
supports 3.10. Guarded behind the exceptiongroup backport that anyio already
pulls in below 3.11.
- 9 missing imports (json, openai, Any, Final, HTTPException), including one in
a helper that catches HTTPException by a name it never imported, so the
challenge path it exists to detect raises NameError instead.
- 5 annotations naming types imported inside the function body, hoisted to
module scope or TYPE_CHECKING.
- 2 blocks of dead code: everything after a pytest.fail in
test_claude_agent_sdk, and an unused helper in test_end_users calling a
function defined in a different module.
- 1 error-path f-string in the router-settings doc test that masked the real
FileNotFoundError behind a NameError.
Only F821 for now. Widening the select list means ratcheting thousands of
pre-existing findings, so rules go in one at a time with their violations
already fixed.
Use importlib.import_module + reload uniformly in both code paths
to ensure fresh module state regardless of whether litellm was
previously in sys.modules. This fixes the inconsistency where the
"not in sys.modules" branch didn't reload the module.

- test_pillar_guardrails.py: Fix fixture to properly update module-level
litellm reference using global keyword and assignment from reload
- test_anthropic_experimental_pass_through_messages_handler.py: Add missing
assert keywords to kwargs comparison statements (lines 36, 60-62)
- test_proxy_server.py: Replace silent pytest.skip with explicit assertion
to catch router initialization regressions

The setup_and_teardown fixture was failing with "ImportError: module
litellm not in sys.modules" during parallel test execution. This occurs
because another worker might have removed/modified litellm from
sys.modules before this test tries to reload it.
Fix: Check if litellm is in sys.modules before attempting reload.
