| """ | |
| Integration tests for complex orchestration workflows. | |
| These tests validate end-to-end workflows that involve multiple components: | |
| - API routes -> Services -> Database | |
| - Agent orchestration with ReAct loops | |
| - Workflow execution with dependencies | |
| - Cross-service interactions | |
| Integration tests are slower but catch issues unit tests miss: | |
| - Component integration errors | |
| - Transaction lifecycle issues | |
| - Async coordination problems | |
| - Real database interaction patterns | |
| Coverage Goal: Address Phase 194 finding (WorkflowEngine 19% unit coverage) | |
