Migrate all unit tests from nock-based HTTP interception to a proper
MSW (Mock Service Worker) mock server using msw/node + @mswjs/interceptors.
Changes:
- Add msw@2 as devDependency, remove nock
- Create tests/mocks/server.ts: MSW server with documentation on adding handlers
- Update tests/setup.js: start/stop/reset MSW server in beforeAll/afterEach/afterAll
- Port all 7 nock-based test files to per-test server.use() handlers:
entities, auth, functions, connectors, integrations, custom-integrations, client
- Replace vi.stubGlobal("fetch", ...) in functions.test.ts with MSW handlers
- Add request capture pattern for asserting headers (Authorization, Base44-State)
- Use RegExp patterns for MSW handlers where operationId contains URL-unsafe chars
All 116 unit tests pass (npm run test:unit exits 0).
Goal: https://github.com/base44-dev/gremlins/issues/873

Pull request overview
This PR migrates the unit test suite from nock-based HTTP interception to an MSW (msw/node, v2) mock server, centralizing request mocking and enabling per-test handlers via server.use().
Changes:
- Added a shared MSW Node server (
tests/mocks/server.ts) and wired its lifecycle into the Vitest global setup (tests/setup.js). - Ported multiple unit test files from
nockto MSW handlers (http.*+HttpResponse), including request capture for header assertions. - Updated dependencies to introduce
msw(and intended to removenock).

Review remediation update for exact published head The previous ready recommendation is retracted. I audited all six open March 26 Copilot conversations individually. Each underlying finding is addressed in the current head, but I have not dismissed or resolved any conversation and do not infer acceptance:
Fresh focused proof at this head passes 5 files/92 tests (client, auth, custom integrations, core integrations and architecture guard); the published full proof remains 23 files/332 tests on default and Node 20. The scoped bridge does not expose GitHub's GraphQL-only thread-resolution mutation, so a maintainer must verify these links and click Resolve conversation for each genuinely addressed finding. The two red Claude jobs are policy failures before analysis, not source failures. Both reject bot actor No merge, review dismissal or human approval is claimed. The PR remains needs-work until all six conversations are resolved and both Claude checks are green. |

Thread-resolution update for exact head After rechecking the current head against the previously published six-finding audit, I resolved exactly those six addressed Copilot threads through the repository-scoped, SHA-bound bridge operation. The fresh paginated readiness result now reports The PR is still incomplete, not ready. Review decision remains |
The SDK’s HTTP tests now run through MSW against the actual Axios/fetch clients. The migration preserves the current-main suite, enforces request/body/header/query expectations, and fails unmatched traffic even when SDK code catches the network error. The earlier migration omitted a Nock test file and weakened several body assertions; this update covers the current test surface and removes transport response stubs.
Stronger multipart assertions exposed a production bug:
functions.invoke(FormData)rebuilt an empty form and lost fields. A separate fix preserves caller-supplied FormData, including repeated keys, empty values and binary files. The old implementation fails the new wire assertions; the fixed implementation passes.Validation:
npm test.src, not the test files.tests/README.mddocuments adding handlers, request assertions, strict teardown, multipart inspection and the unit/live-E2E boundary. Goal c9/c10 evidence is prepared for human acceptance; this PR has not been merged.Review scope
The actual GitHub comparison has been verified against current main (
