test(proxy/proxy_server): pin control-plane routes (PR3)#28850
Conversation
Adds happy + error tests for the misc control-plane routes: GET /, /routes, /adaptive_router/state, /get_logo_url, /get_image, /get_favicon. Also gitignores .pin_list.txt (used by the pin gate).
Adds happy + error tests for the 5 login/SSO control-plane routes: GET /fallback/login, POST /login, POST /v2/login, POST /v3/login, POST /v3/login/exchange. Mocks authenticate_user and create_ui_token_object at their imported location.
Adds happy + error tests for the 2 onboarding control-plane routes: GET /onboarding/get_token, POST /onboarding/claim_token. Wires a MagicMock async context manager for prisma_client.db.tx() and signs the onboarding JWT with the patched master_key.

Greptile SummaryThis PR fills in the 7 placeholder test files from the PR3 harness, adding 107 behavior-pinning tests for 34 control-plane routes across login/SSO, onboarding, invitation, config CRUD, model-cost-map reload, Anthropic-beta-headers reload, and misc routes. All tests use only the shared
Confidence Score: 4/5This is a purely additive test-only PR with no production code changes; the main risk is a small number of assertions that are too weak to catch the regressions they appear to guard against. The two trivially-true assertions mean two tests will pass unconditionally and never detect a regression on those error paths, defeating the purpose of pinning them. The rest of the 107 tests are well-structured with tight dict-equality checks via normalize(), proper volatile-key handling, and good role/auth coverage. tests/test_litellm/proxy/proxy_server/test_routes_misc.py and test_routes_login_sso.py contain the non-failing assertions; test_routes_anthropic_beta.py has the brittle JSON string check.
|
| Filename | Overview |
|---|---|
| tests/test_litellm/proxy/proxy_server/test_routes_misc.py | Pins 6 misc routes. Contains a trivially-true assertion (b"" in response.content) that never fails and provides no regression protection. |
| tests/test_litellm/proxy/proxy_server/test_routes_login_sso.py | Pins 5 login/SSO routes. One 500-error test uses len(response.content) >= 0 which is always True and gives no signal on whether an error body is actually returned. |
| tests/test_litellm/proxy/proxy_server/test_routes_anthropic_beta.py | Pins 4 Anthropic-beta reload/schedule routes. One test uses brittle string-literal JSON assertions that depend on exact serialization spacing. |
| tests/test_litellm/proxy/proxy_server/test_routes_config.py | Pins 8 config routes. One error-path test accepts both 404 and 500, weakening the pin; all other assertions are tight dict-equality checks. |
| tests/test_litellm/proxy/proxy_server/test_routes_invitation.py | Pins 4 invitation CRUD routes with solid dict-equality assertions and proper volatile-key handling; no issues found. |
| tests/test_litellm/proxy/proxy_server/test_routes_model_cost_map.py | Pins 5 model-cost-map reload/schedule routes with tight dict-equality assertions and proper mock isolation; no issues found. |
| tests/test_litellm/proxy/proxy_server/test_routes_onboarding.py | Pins 2 onboarding routes including JWT decode assertion; thorough edge-case coverage (expired invite, user_id mismatch, missing fields). |

Trivially-true assertion —
b"" in response.content is always True (the empty bytes literal is a substring of every bytes object), so this check can never fail and provides zero regression protection. The guard also short-circuits the or, meaning the content-type side is never even evaluated. The test's stated intent is to verify a non-empty body is returned.

len(response.content) >= 0 is trivially true — the length of a bytes object is always non-negative, so this assertion never fails regardless of what the server returns. A future refactor that produces an empty body on a 500 would silently pass. The intent is clearly to verify the response carries a body.

These string-literal checks on a JSON-serialized payload are brittle: they rely on
json.dumps always emitting a space after the colon (e.g. "interval_hours": 12 vs "interval_hours":12). Python's default serializer does add that space, but any call-site that passes separators or uses a different serializer would break this assertion even though the data is correct. Prefer inspecting the deserialized dict directly.

Overly-permissive status-code assertion weakens the pin
Accepting both 404 and 500 means the test will not catch a regression where the route starts returning a generic 500 instead of a proper 404. The comment explains this accommodates a known ProxyException wrapping issue, but that means the production error-handling path is currently broken for this case. Consider pinning to the actually-observed code, or asserting only 404 and fixing the underlying wrapping.
- test_routes_misc.py: `b"" in response.content` is trivially true; replace with `len(response.content) > 0` so an empty 405 body trips the gate. - test_routes_login_sso.py: `len(response.content) >= 0` is trivially true; tighten to `> 0`. - test_routes_anthropic_beta.py: replace brittle string-literal checks on the serialized JSON (`'"interval_hours": 12' in payload`) with `json.loads` + dict access so the assertion survives any serializer spacing. - test_routes_config.py: `assert status_code in (404, 500)` was too permissive; the handler re-raises HTTPException(404) verbatim, so pin 404 strictly.
Apply the same review feedback Greptile gave on PR1 (#28856) and PR3 (#28850) to PR2's forwarding-route tests: - Replace permissive `>= 400` / `in (X, Y)` status assertions with the exact 500/405 the handler actually returns, so a regression that silently shifts the code now fails the pin. - Add a body-presence check alongside each tightened status assertion to satisfy _pin_check.py's no-status-only rule.

Summary
PR3 of the proxy_server.py behavior-pinning project — fills the 7 PR3 placeholder files left empty by the harness PR (#28827) with happy + error tests for the 34 control-plane routes in the pin list. Pins HTTP-boundary behavior of admin, login/SSO, onboarding, invitation, config CRUD, model-cost-map reload, anthropic-beta-headers reload, and misc routes via dict-equality assertions, so future refactors of
