test(integration): add MCP gateway coverage wave 1 with a dedicated mcp shard and proxy coverage artifact (#42711)
* test(integration): drop the contracts.json manifest and the covers requirement Groups live as a GROUPS literal in run.py, the browser expectations move next to the browser tests, and the runner fails only on pytest failure, collection errors or a selected file that collects zero tests. The covers marker stays registered for the existing tests but is no longer checked. The mcp directory gets its own group Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * ci(integration): run mcp as its own shard with xdist and a peer proxy Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * ci(integration): INTEGRATION_COVERAGE=1 runs the proxy under coverage for the MCP modules The mcp shard sets it. The proxy and its peer start under coverage run in parallel mode, get SIGTERM after the tests so coverage flushes, and the combined text and HTML reports land in the suite results that CircleCI already stores as artifacts Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * ci(integration): let the test proxy flush coverage when uvicorn re-raises SIGTERM Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(integration): add SSE, stdio, scripted, OpenAPI and OAuth 2.1 MCP peer doubles Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(integration): add MCP transport and access-control matrices Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(integration): add MCP credential and OAuth flow coverage Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(integration): add MCP LLM endpoint, accounting, guardrail, resilience and lifecycle coverage Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(integration): stop the same-URL grant test from counting a late initialize as a leaked call and satisfy the test-tree lint Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(integration): assert the REST denied-server listing is refused or empty Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(integration): pin the REST denied-server listing to 403 access_denied Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> --------- Co-authored-by: yuneng <yuneng@berri.ai> Co-authored-by: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

Use `tests/integration/run.py management`, `accounting`, `database`, `providers`, `extensions`, `mcp`, `sdk` or `cost` to run a selected group. The group to directory mapping is the `GROUPS` literal at the top of `run.py`; a new directory needs a `GROUPS` entry and an `OWNED_DIRECTORIES` entry in `_support/manifest.py`. Set `INTEGRATION_WORKERS` above 1 to run a group under pytest-xdist; the `mcp` job does this in CI, so MCP tests must own their resources per scenario.

Management also requires `INTEGRATION_PEER_URL`, `REDIS_HOST` and `REDIS_PORT`. CircleCI starts two directly addressed proxy processes sharing only that job's stores.

The CircleCI workflow starts its own database and Redis, restricts test-phase egress to its owned services and writes JUnit plus an executed-node manifest. Missing setup, failed cleanup or a selected test with neither a passed call nor a skip fail qualification. Skipped nodes are listed under `skipped` in `execution.json`, so the skip reasons double as the open bug list. Existing GitHub Actions jobs do not own these tests
|
||||
|
||||
Define integration contract IDs and their canonical test nodes in `contracts.json`. Every node must declare the same IDs with `covers`. The runner checks exact collected and passed-or-skipped selections against that mapping. These IDs belong to this CircleCI suite and must not be added to the separate E2E coverage registry. A manifest declaration alone does not mean a test passed
|
||||
There is no per-node manifest. The runner fails only when pytest fails, when collection errors, or when a selected file collects zero tests. Older tests still carry `@pytest.mark.covers(...)` decorators; the marker stays registered so they collect, but the IDs are not checked against anything and new tests should not use it. The GitHub Actions coverage census reads the `GROUPS` literal in `run.py` and treats every `tests/integration/<directory>/test_*.py` file in a scheduled group as owned by CircleCI

Provider sentinels currently use the controlled server, not live recordings. The provider shard also runs the existing strict replay controls for changed requests, exhausted interactions, leftover interactions and no provider connection. Future recorded scenarios must use that replay-only implementation; missing recordings cannot fall back to a real provider. The observation endpoint is destructive and the current selection runs serially against one owned upstream

The sdk shard exercises the SDK's own HTTP clients against local protocol peers with no gateway in the path, so a case here fails only when the client library or its wire behavior changes. The HTTP/2 case runs a hypercorn TLS peer offering h2 and http/1.1 over ALPN, drives the sync and async httpx handlers at it with `LITELLM_HTTP2` off and on, and asserts the version both the client and the peer observed on the wire. Put a test here only when it needs no proxy, database or Redis; a case that reaches the gateway belongs in one of the other shards

The extensions shard reuses the existing MCP arithmetic functions with a real SDK server, and uses the built-in generic callback and guardrail transports. It checks actual tool calls after saved edits, discovery preservation, malformed/error responses, callback correlation and credential exclusion, guardrail rewriting and denial, retained OpenAI consumers, persisted toolsets and A2A wire versions

Browser contracts live in `tests/e2e/ui/tests/integrationCritical` and run only through `tests/e2e/ui/integration.config.ts`. The CircleCI browser shard builds the checked-out dashboard, starts the owned proxy with that build, and verifies one exact browser result without retries or skips. The default Playwright selection excludes this directory. The focused project flow asserts the submitted create and clear values, fresh SQL state and actual blocked/restored serving while preserving model restrictions
|
||||
The mcp shard runs the MCP gateway against SDK peers owned by each test (`_support/mcp.py`): streamable HTTP, SSE and stdio peers, an OpenAPI-spec app, and an OAuth 2.1 authorization-server double. Every peer records the requests it receives so a test can assert what reached the peer, not only what the proxy answered. The shard runs with `INTEGRATION_WORKERS` set and with `INTEGRATION_COVERAGE=1`, which starts the proxy under `coverage run --parallel-mode` limited to the MCP modules and stores `coverage.txt` plus an HTML report with the job artifacts. A test that fails because the product is wrong is skipped with `pytest.skip("BUG: <symptom>")` so the skip list in `execution.json` is the open MCP bug list

Browser contracts live in `tests/e2e/ui/tests/integrationCritical` and run only through `tests/e2e/ui/integration.config.ts`. The expected browser results are listed in `expected.json` in that directory and checked by `.circleci/scripts/verify_integration_browser.py`. The CircleCI browser shard builds the checked-out dashboard, starts the owned proxy with that build, and verifies one exact browser result without retries or skips. The default Playwright selection excludes this directory. The focused project flow asserts the submitted create and clear values, fresh SQL state and actual blocked/restored serving while preserving model restrictions
