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).

Unit tests for AsyncTaskManager and TaskWrapper.
|
|
|
|
Tests cover async task lifecycle management:
|
|
- Task scheduling and tracking
|
|
- Task completion
|
|
- Task exception handling
|
|
- Task cancellation
|
|
- Multiple task isolation
|
|
|
|
Uses module mocking to break circular import chain.
