# 88 - Testing & Documentation (TASK-041 P5)

**Date:** 2025-12-03
**Version:** -
**Task:** TASK-041-15, TASK-041-16

---

## Summary

Implemented Phase P5 of TASK-041 (Router YAML Workflow Integration) - Integration tests and complete documentation for the YAML workflow system.

---

## Changes

### New Files

| File | Purpose |
|------|---------|
| `tests/unit/router/application/workflows/test_yaml_workflow_integration.py` | 14 integration tests |
| `server/router/application/workflows/custom/test_workflow.yaml` | Test workflow for validation |
| `_docs/_ROUTER/WORKFLOWS/yaml-workflow-guide.md` | Complete YAML workflow guide |
| `_docs/_ROUTER/WORKFLOWS/expression-reference.md` | Expression syntax reference |

---

## TASK-041-15: Integration Tests

**14 tests** covering complete workflow scenarios:

| Test Class | Tests | Coverage |
|------------|-------|----------|
| `TestYAMLWorkflowLoading` | 2 | Custom workflow loading |
| `TestKeywordTriggerActivation` | 3 | Keyword matching |
| `TestCalculateExpressionEvaluation` | 1 | $CALCULATE expressions |
| `TestConditionBasedStepSkipping` | 3 | Condition evaluation |
| `TestAutoParameterResolution` | 2 | $AUTO_* parameters |
| `TestFullWorkflowPipeline` | 1 | Pipeline execution |
| `TestMixedParameterTypes` | 1 | Mixed param types |
| `TestContextSimulationInWorkflow` | 1 | Context simulation |

### Test Scenarios

1. **YAML workflow loads and executes** - Custom workflows from `custom/` directory
2. **Keyword trigger activates workflow** - "create a phone" → phone_workflow
3. **$CALCULATE expressions evaluate** - `$CALCULATE(min_dim * 0.05)` → 0.025
4. **Conditions skip appropriate steps** - `current_mode != 'EDIT'` → skipped in EDIT
5. **$AUTO_* params resolve to correct values** - `$AUTO_BEVEL` → 5% of min dim
6. **Context simulation prevents redundant steps** - Second mode switch skipped
7. **Mixed parameter types all resolve** - $CALCULATE + $AUTO + literals

## TASK-041-16: Documentation

### yaml-workflow-guide.md

Complete guide covering:
- File structure and location
- Basic YAML structure
- Step definitions
- Conditional steps with all operators
- Dynamic parameters ($CALCULATE, $AUTO_*, $variable)
- Triggering mechanisms
- Best practices
- Troubleshooting guide

### expression-reference.md

Technical reference for:
- $CALCULATE arithmetic and functions
- $AUTO_* parameter catalog
- Condition expression syntax
- Variable availability
- Resolution order
- Error handling
- Security considerations

---

## Test Workflow

Created `test_workflow.yaml` for validation:

```yaml
name: test_e2e_workflow
description: Test workflow for E2E validation
trigger_keywords: [test, e2e_test, yaml_test]

steps:
  - tool: modeling_create_primitive
    params: { type: CUBE }

  - tool: system_set_mode
    params: { mode: EDIT }
    condition: "current_mode != 'EDIT'"

  - tool: mesh_select
    params: { action: all }
    condition: "not has_selection"

  - tool: mesh_bevel
    params:
      width: "$AUTO_BEVEL"
      segments: 3

  - tool: mesh_inset
    params:
      thickness: "$CALCULATE(min_dim * 0.03)"

  - tool: mesh_extrude_region
    params:
      move: [0, 0, "$AUTO_EXTRUDE_NEG"]
```
