Summary

scripts/run-mock-tests.sh skipped 13 test files, so test:mock never ran them (no npm script or workflow did either). This PR wires in the 11 that run against the mock GitLab server. It also updates the tests whose expectations no longer match how the server behaves today.

Now run by test:mock:

  • unit pass: config-allowed-groups.test.ts, no-proxy-test.ts
  • server pass: callback-proxy-tests.ts, client-pool-test.ts, dynamic-api-url-test.ts, dynamic-routing-tests.ts, multi-server-test.ts, no-proxy-integration-test.ts, test-mr-diffs-filter.ts, test-mr-file-diffs.ts, test-token-optimizations.ts

The server-pass glob now matches *-test.ts. Before, it listed only remote-auth-simple-test.ts. A dry run of both find expressions shows exactly these 11 files added, none dropped, and no file in both passes.

Test fixes

File Was failing because Change
client-pool-test.ts X-GitLab-API-URL must name a host from GITLAB_API_URL / GITLAB_ALLOWED_HOSTS List the mock hosts in GITLAB_ALLOWED_HOSTS. The third pool entry is now a second local mock server instead of gitlab-3.example.com, so the test makes no external network call
dynamic-api-url-test.ts same List both mock hosts in GITLAB_ALLOWED_HOSTS
dynamic-routing-tests.ts Scenario 1: Streamable HTTP with a server-side token needs STREAMABLE_HTTP_AUTH_TOKEN. Scenario 4: header URL not configured, and list_pipelines is not in the default toolsets Set STREAMABLE_HTTP_AUTH_TOKEN (Scenario 1 still checks that client headers are not forwarded to GitLab; Scenario 3 sets it too so it still fails only on the dynamic-URL rule). Scenario 4 sets GITLAB_ALLOWED_HOSTS and GITLAB_TOOLSETS=all
multi-server-test.ts A header URL that is not configured is now refused at connect, not at the tool call Assert that connect is refused with the missing-header response
no-proxy-integration-test.ts The token is checked against GitLab when the session starts, so the proxy error comes from connect Accept the error from either connect or the tool call, and check that the mock GitLab server saw no request (so a failure that skipped the proxy does not pass). Also replaces an assert.fail that its own catch swallowed

test/README.md is updated to match.

Still excluded

remote-auth-tests.ts and test-all-transport-server.ts need a live GitLab token and TEST_PROJECT_ID; they process.exit(1) without one. remote-auth-tests.ts also sends a client-chosen mcp-session-id on initialize, which the server now answers with 404. So it needs a rewrite onto the mock server, not a re-enable. remote-auth-simple-test.ts already covers the mock-based remote auth cases. I'd do both as a follow-up.

Test plan

scripts/run-mock-tests.sh skipped 13 test files, so test:mock never ran
them. Wire in the 11 that run against the mock GitLab server and update
the ones whose expectations drifted from current server behavior:

- client-pool-test, dynamic-api-url-test, dynamic-routing-tests: list
  the mock GitLab hosts in GITLAB_ALLOWED_HOSTS so X-GitLab-API-URL can
  route to them. client-pool-test uses a second local mock server as
  its third pool entry instead of an external hostname.
- dynamic-routing-tests: set STREAMABLE_HTTP_AUTH_TOKEN where the server
  uses a server-side token, and enable all toolsets for the scenario
  that calls list_pipelines.
- multi-server-test: a header URL that is not configured is refused at
  connect; assert that instead of a failed tool call.
- no-proxy-integration-test: the token is checked when the session
  starts, so the proxy error can surface on connect.

The server pass now matches *-test.ts. remote-auth-tests.ts and
test-all-transport-server.ts still need a live GitLab token and stay
excluded.

📝 Summary

Summary by CodeRabbit

  • Tests

    • Expanded mock-test coverage for configuration, access-control, and proxy scenarios.
    • Updated connection tests to reflect authentication failures during setup and errors during connection or project requests.
    • Revised mock server setups to use configured endpoints and tokens, and strengthened checks for server capacity and unexpected requests.
  • Documentation

    • Updated the test guide to clarify mock-test selection and the requirements for tests that still use live services.

The mock-test runner selects additional tests and updates filename matching. Integration tests configure local mock servers and authentication settings, and adjust expectations for connection failures.

Changes: Mock Test Suite

Layer / File(s) Summary
Mock-test selection and documentation
scripts/run-mock-tests.sh, test/README.md
The mock-test selections include additional tests and use a broader *-test.ts pattern. The README updates the list of tests outside the mock pass and their stated requirements.
Mock-server test configuration
test/client-pool-test.ts, test/dynamic-api-url-test.ts, test/dynamic-routing-tests.ts
The pool test uses a second local mock server for its third distinct pool entry. Dynamic API URL tests allow both mock hosts. Routing scenarios configure MCP authentication, allowed hosts, and toolsets.
Connection failure expectations
test/multi-server-test.ts, test/no-proxy-integration-test.ts, test/utils/mock-gitlab-server.ts
The multi-server test expects an unconfigured API URL to fail during connection. The no-proxy test checks for rejection during connection or the first tool call and verifies that the mock server received no requests. The mock server exposes its request count.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Merge Risk: 🔵 Low · up to 62f69

The mock suite may miss a broken proxy path because unrelated authentication or network failures can satisfy the no-proxy test. This is a bounded test-confidence risk, not evidence of a production failure.

- Line 189: Update the rejection assertion in the test around
client.connect(mcpUrl) to match the existing missing-authentication-header
response, rather than the generic “Failed to connect” message. Keep the test’s
valid credentials and host-validation scenario unchanged.

Review comments at @test/no-proxy-integration-test.ts:
- Around line 130-133: Update the `assert.rejects` check in this test to match
the expected proxy connection error, rather than only supplying an assertion
message. Allow the matching rejection to come from either `client.connect` or
`client.callTool`, and ensure unrelated failures such as authentication errors
do not pass.

Review comments at @test/README.md:
- Line 43: Update the test naming patterns in the “Adding a test” instructions
to include `*-test.ts`, matching the pattern selected by Pass 3.

Comment thread test/README.md
multi-server-test now matches the missing-header response instead of any
connect failure. no-proxy-integration-test matches the rejection and
checks that the mock GitLab server saw no request, so a failure that
skipped the proxy no longer passes. test/README.md lists *-test.ts in
the naming guidance.
