Every happy-path test asserts the full response dict via normalize() so the gate enforces real shape pinning rather than status codes. * test(proxy): drop task-plumbing comments from PR2 test files * test(proxy): tighten PR2 error-path status-code pins 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. --------- Co-authored-by: Claude <noreply@anthropic.com> * test(proxy): pin proxy_server.py non-route surface behavior (PR1) (#28856) * test(proxy): pin proxy_server.py non-route surface behavior (PR1) Fills the 7 PR1 placeholder files under tests/test_litellm/proxy/proxy_server/ with behavior pins for the non-route surface of proxy_server.py: lifecycle/init/shutdown, ProxyConfig class methods, DB-overlay config scrubbers, spend counters, background-health helpers, OpenAPI customization, exception handlers, and streaming-generator helpers. 233 tests cover 101 pin-list symbols (1+ happy + 1+ error each). New-tests-only coverage on litellm/proxy/proxy_server.py: 32.80% line / 20.91% branch (PR1 gate: 25% line / 18% branch). Full directory runs in ~22s with -n 4. Plan: https://www.notion.so/Plan-Pin-proxy_server-py-behavior-2026-05-25-36c43b8acdab81ee845fd5365128a2fc * test(proxy): address Greptile review comments on test_lifecycle.py - test_initialize_signature_is_async_with_expected_params: hard-code expected_param_count so a signature change actually trips the gate (previously both sides of the comparison were len(sig.parameters)). - test_check_request_disconnection_invalid_when_connected_times_out: patch asyncio.sleep so the test no longer spins for ~1.2 s of real wall-clock; timeout lowered to 0.05 s. --------- Co-authored-by: Claude <noreply@anthropic.com> * test(proxy/proxy_server): pin control-plane routes (PR3) (#28850) * test(proxy/proxy_server): pin misc routes (PR3, partial) 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). * test(proxy/proxy_server): pin login/SSO routes (PR3, partial) 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. * test(proxy/proxy_server): pin onboarding routes (PR3, partial) 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. * test(proxy/proxy_server): pin model_cost_map reload routes (PR3, partial) Adds happy + error tests for the 5 model-cost-map control-plane routes: POST /reload/model_cost_map, POST|DELETE|GET /schedule/model_cost_map_reload(/status), GET /model/cost_map/source. Attaches litellm_config to mock_prisma per-test (the table is not in the default _PRISMA_TABLES fixture). * test(proxy/proxy_server): pin anthropic_beta_headers reload routes (PR3, partial) Adds happy + error tests for the 4 anthropic-beta-headers control-plane routes: POST /reload/anthropic_beta_headers, POST|DELETE|GET /schedule/anthropic_beta_headers_reload(/status). Stubs db.litellm_config (not in default _PRISMA_TABLES) and monkeypatches reload_beta_headers_config so no network calls fire. * test(proxy/proxy_server): pin invitation routes (PR3, partial) Adds happy + error tests for the 4 invitation control-plane routes: POST /invitation/new, GET /invitation/info, POST /invitation/update, POST /invitation/delete. Patches _user_has_admin_privileges / _user_has_admin_view to avoid extensive get_user_object mocking. * test(proxy/proxy_server): pin config CRUD routes (PR3, partial) Adds happy + error tests for the 8 config-CRUD control-plane routes: POST /config/update, POST|GET /config/field/update|info, GET /config/list, POST /config/field/delete, POST /config/callback/delete, GET /get/config/callbacks, GET /config/yaml. Attaches litellm_config to mock_prisma per-test. * test(proxy/proxy_server): tighten pin assertions per review - 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. --------- Co-authored-by: Claude <noreply@anthropic.com> --------- Co-authored-by: Claude <noreply@anthropic.com>	2026-05-29 23:17:24 -07:00
yuneng-jiang	f38c16c71e	test(proxy): add harness for proxy_server.py behavior-pinning (#28827) ... * test(proxy): add harness for proxy_server.py behavior-pinning Creates tests/test_litellm/proxy/proxy_server/ with: - conftest.py: 11 shared fixtures (app, client, mock_prisma, auth_as, mock_router with parametrized response builders, normalize, etc.) - _coverage_check.py: per-PR coverage gate (line + branch) against a baseline, self-selects target by inspecting which placeholder files have been filled - _pin_check.py: AST-based gate that verifies every pin-list item has >=1 happy + >=1 error test with a real assertion (no status-only) - test_harness_smoke.py: 19 smoke tests covering every fixture + both scripts end-to-end - 26 placeholder test files (one docstring each) reserved for follow-up PRs per the directory ownership in the Notion plan - .coverage_baseline pinned at 0% so future PRs measure deltas against new-tests-only and aren't entangled with the broader scattered test suite Adds a dedicated proxy-server job to test-unit-proxy-endpoints.yml so this directory's runtime + coverage are tracked independently. Plan: https://www.notion.so/36c43b8acdab81ee845fd5365128a2fc * ci(proxy-endpoints): allow workflow_dispatch Lets the workflow be triggered manually on a branch via `gh workflow run`, which is needed for the verify-first flow on workflow changes before opening a PR. * test(proxy): address review feedback on proxy_server harness - conftest.py: anchor sys.path insert to __file__ (Path(__file__).resolve().parents[4]) instead of CWD-relative os.path.abspath("../../../../") which resolved to the wrong directory when pytest is launched from the repo root. - _coverage_check.py: actually read .coverage_baseline and use it as the floor (line_min = max(target, baseline)). Closes the gap between the PR description's "delta semantics" and what the script was doing. With baseline=0.0 today this is a no-op; future PRs that update the baseline cause regressions (test deletions etc.) to trip the gate even if the static PR target is still met. - _pin_check.py: drop unreachable startswith("_") guard (test_*.py glob never yields underscore-prefixed names) and read each test file once instead of twice.	2026-05-25 20:26:44 -07:00
