# Changelog 77: Router E2E Test Suite

**Date:** 2025-12-01
**Type:** Testing
**Task:** TASK-039-23

## Summary

Implemented comprehensive E2E test suite for Router Supervisor. Tests cover scenarios, workflows, pattern detection, and full pipeline execution.

## Changes

### New Files

├── __init__.py
├── conftest.py                  # E2E fixtures with RPC skip
├── test_router_scenarios.py     # Mode correction, param clamping
├── test_workflow_execution.py   # Workflow tests
├── test_pattern_detection.py    # Pattern detection tests
└── test_full_pipeline.py        # Full pipeline integration
```

### Test Categories

| Category | Tests | Description |
|----------|-------|-------------|
| Router Scenarios | 7 | Mode correction, param clamping, selection |
| Workflow Execution | 9 | Phone, tower, screen cutout workflows |
| Pattern Detection | 10 | Geometry pattern detection |
| Full Pipeline | 12 | Complete pipeline, error recovery, config |
| **Total** | **38** | |

### Test Types

1. **Router Logic Tests (26)** - Work without Blender
   - Test router corrections
   - Test workflow expansion
   - Test parameter clamping

2. **Blender Integration Tests (12)** - Require running Blender
   - Test real geometry detection
   - Test RPC communication
   - Test actual tool execution

### Running E2E Tests

```bash
# All E2E tests (will skip if Blender not running)
PYTHONPATH=. poetry run pytest tests/e2e/router/ -v

# With Blender running
# 1. Start Blender with addon
# 2. Run tests
PYTHONPATH=. poetry run pytest tests/e2e/router/ -v
```

## Test Coverage

- Mode correction scenarios
- Parameter clamping (bevel, subdivide)
- Selection handling
- Workflow execution (phone, tower, screen cutout)
- Pattern detection (phone_like, tower_like, cubic)
- Error recovery
- Configuration options
