From 76f778c10d1ce479584a3dc188d392a966b1a9d8 Mon Sep 17 00:00:00 2001 From: asepharyana Date: Thu, 20 Aug 2026 11:12:32 +0700 Subject: [PATCH] =?UTF-8?q?chore(testing):=20Phase=209=20=E2=80=94=20bun:t?= =?UTF-8?q?est=20suite=20+=20CI=20gating=20with=20no-DB=20fakes?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Added a real test suite (32 tests, 0 external services) using bun:test with in-process module mocking for @mcpedia/db, @mcpedia/queue, @mcpedia/core. Enablers: - apps/api: extracted createApp(deps?) factory + dashboard.ts module from index.ts so the HTTP surface is unit-testable (real queue is lazy-imported). - packages/core: exported shouldCreateRevision pure predicate; restoreRevision gained an opts.reindex seam for the chunk-rebuild contract. - apps/mcp: renamed smoke.test.ts -> smoke.ts (bun test now owns .test.ts), updated stale assertions (10 tools, 4 docs in docs section). - infra: turbo test task (cache:false), test scripts across packages, @types/bun + tsconfig base types, CI 'Test' step after Build. Packages with tests: embeddings(5), parser(5), search(8), core(4), mcp(6 auth-gates), api(8 contracts). All green: typecheck(4/4), test(6/6 pkgs), build(web). Live API verified /health, /metrics, /dashboard, /hooks/* auth gate on temp port. --- .github/workflows/ci.yml | 6 + .hermes/plans/phase9-spec.md | 157 ++++++++++++++++++ PHASES.md | 57 +++++++ apps/api/package.json | 3 +- apps/api/src/app.test.ts | 133 +++++++++++++++ apps/api/src/app.ts | 170 +++++++++++++++++++ apps/api/src/dashboard.ts | 63 +++++++ apps/api/src/index.ts | 200 ++--------------------- apps/mcp/package.json | 3 +- apps/mcp/src/auth.test.ts | 171 +++++++++++++++++++ apps/mcp/src/{smoke.test.ts => smoke.ts} | 6 +- bun.lock | 5 + package.json | 4 +- packages/core/package.json | 3 + packages/core/src/index.service.test.ts | 44 +++++ packages/core/src/index.service.ts | 16 ++ packages/core/src/revision.service.ts | 14 +- packages/embeddings/package.json | 3 + packages/embeddings/src/chunk.test.ts | 57 +++++++ packages/parser/package.json | 3 + packages/parser/src/parse.test.ts | 81 +++++++++ packages/search/package.json | 3 + packages/search/src/cosine.test.ts | 40 +++++ tsconfig.base.json | 3 +- turbo.json | 3 + 25 files changed, 1055 insertions(+), 193 deletions(-) create mode 100644 .hermes/plans/phase9-spec.md create mode 100644 apps/api/src/app.test.ts create mode 100644 apps/api/src/app.ts create mode 100644 apps/api/src/dashboard.ts create mode 100644 apps/mcp/src/auth.test.ts rename apps/mcp/src/{smoke.test.ts => smoke.ts} (96%) create mode 100644 packages/core/src/index.service.test.ts create mode 100644 packages/embeddings/src/chunk.test.ts create mode 100644 packages/parser/src/parse.test.ts create mode 100644 packages/search/src/cosine.test.ts diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 90b5aca..4fa1170 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -41,3 +41,9 @@ jobs: # module load + in-memory smoke test. - name: MCP smoke test run: bun --cwd apps/mcp run smoke + + # Unit tests across all packages + apps.
