""" Coverage expansion tests for workflow API routes. Tests cover critical code paths in: - api/workflow_template_routes.py: Workflow template CRUD, execution, import - api/ai_workflows_routes.py: AI workflow completion, NLU parsing - Workflow instantiation, search, and provider management Target: Cover critical paths (happy path + error paths) to increase coverage. Uses extensive mocking to avoid database dependencies.
