Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * feat(test): add fake provider factory Add tests/factories/provider.py with: - FakeProvider: deterministic fake LLM provider - Error simulation: timeout, auth, rate-limit, malformed - Request capture for assertions - fake_model: mock model with attached provider Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * feat(test): add fake platform factory Add tests/factories/platform.py with: - FakePlatform: simulated platform adapter - Inbound message construction: friend/group/image - Mention-bot flag simulation - Outbound message capture for assertions - Streaming output support simulation - Send failure simulation Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * feat(test): add comprehensive message/query factories Extend tests/factories/message.py with: - file_query: file attachment query - unsupported_query: unknown message segment - voice_query: audio/voice query - at_all_query: group @All mention - query_with_session: query with session object - query_with_config: query with custom pipeline config Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * feat(test): add fake message flow smoke test Create tests/smoke/test_fake_message_flow.py: - TestFakeMessageFlow: factory verification tests - TestMessageFlowIntegration: minimal flow smoke test - Tests FakeApp, FakeProvider, FakePlatform, query factories - Verifies LANGBOT_FAKE_PONG marker response - Captures outbound messages for assertions Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * feat(test): add developer test-quick command Add scripts/test-quick.sh and Makefile with: - test-quick: runs ruff check + unit tests + smoke tests - No real provider keys or platform accounts required - Suitable for local branch self-test Update tests/README.md: - Document test-quick command - Document test factories package - Add smoke tests and factories directory structure Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(test): make test-quick reliable as developer gate Fixes for D-001验收问题: 1. test-quick.sh: use set -euo pipefail, uv run ruff, no tail pipe 2. Remove unused imports in factories (app.py, platform.py, provider.py) 3. Fix unused variable in smoke test 4. Add noqa: E402 to test_n8nsvapi.py lazy imports 5. Update smoke test docs: "minimal fake flow" not full pipeline Now test-quick is a reliable gate: lint failures exit 1, test failures propagate.

Direct imports of handler modules trigger circular import chain.
