* fix(ci): update unit-test workflow paths to match current source layout

Replace stale pkg/** filter with src/langbot/** and add uv.lock.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* docs(tests): update README to reflect current test layout

- Fix stale paths: tests/pipeline → tests/unit_tests/pipeline
- Update CI Python versions: 3.11, 3.12, 3.13
- Add test directory structure for box, config, platform, plugin, provider, storage
- Document pytest markers and uv commands
- Mention planned E2E tests

* feat(test): add shared test factories package

Create tests/factories/ with reusable test factories:
- FakeApp: mock application with all dependencies
- Message chains: text_chain, mention_chain, image_chain
- Query factories: text_query, group_text_query, command_query, etc.

No test changes - maintains backward compatibility.

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.

* test(unit): add preproc and taskmgr unit tests

U-001: Pipeline Preprocessor tests
- Normal text message processing
- Empty message handling
- Image segment with/without vision model
- Model selection and fallback
- Variable extraction

U-004: Core Task Manager tests (pattern-based)
- Task creation and tracking patterns
- Task cancellation patterns
- Scope-based cancellation
- Task type filtering
- Pruning completed tasks
- Wait all tasks

Taskmgr tests use pattern-based approach to avoid circular import
in source code (taskmgr → app → http_controller → migration → taskmgr).

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* test(unit): add config loader unit tests

U-005: Config Loader tests
- Valid YAML config loading
- Valid JSON config loading
- Invalid YAML/JSON error behavior
- Missing config file creation from template
- Template completion for missing keys
- ConfigManager load/dump operations
- Exists check for both YAML and JSON

All tests use tmp_path fixture, no real project config.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* test(unit): add chat and command handler pattern tests

U-002: Chat Handler tests (pattern-based)
- Normal message event emission pattern
- prevent_default handling
- User message alteration pattern
- Runner selection pattern
- Streaming/non-streaming response patterns
- Exception handling modes (show-error, show-hint, hide)
- Message history update pattern
- Telemetry payload pattern

U-003: Command Handler tests (pattern-based)
- Command parsing and text extraction
- Event creation pattern
- Privilege/admin check pattern
- Command result handling (text, error, image)
- prevent_default handling
- String truncation helper

Uses pattern-based testing to avoid circular import issues in source code.
Direct imports of handler modules trigger circular import chain.

* style: fix unused imports after ruff auto-fix

Remove unused imports in test files:
- test_config_loader.py: remove unused os
- test_taskmgr.py: remove unused Mock
- test_preproc.py: remove unused unsupported_query, image_chain

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* test(unit): improve taskmgr tests to test real classes

U-004 improved: Tests now import and test actual classes:
- TaskContext: new(), trace(), to_dict(), placeholder()
- TaskWrapper: task creation, context, exception/result capture, cancel, to_dict
- AsyncTaskManager: create_task, create_user_task, cancel_task, cancel_by_scope
- Task pruning behavior

Uses pre-mocking technique:
- Mock langbot.pkg.core.app before import (breaks circular chain)
- Mock langbot.pkg.core.entities with proper Enum

All 24 tests now test real class behavior, not patterns.
taskmgr.py coverage should improve significantly.

- Full Local: all three combined

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
