# Tutorial-Based Testing Framework - Implementation Summary

## Overview

Successfully implemented a comprehensive tutorial-based testing framework that mirrors actual ADRI user workflows. This framework transforms how ADRI tests are structured by using real tutorial data as the foundation for test scenarios.

**Implementation Date:** March 10, 2025
**Status:** ✅ Complete - Ready for Validation

## What Was Implemented

### Phase 0: Auto-Discovery Framework (March 10, 2025 - Latest Addition)
✅ **Created `tests/fixtures/tutorial_discovery.py`**
- `find_tutorial_directories()` - Automatically discovers all tutorials
- `validate_tutorial_structure()` - Validates file naming conventions
- `extract_use_case_name()` - Parses use case from filenames
- `TutorialMetadata` dataclass for discovered tutorial info

✅ **Enhanced `tests/fixtures/tutorial_scenarios.py`**
- `discover_all_tutorials()` - Returns list of tutorial names for parametrization
- `setup_tutorial_from_directory()` - Generic setup for any discovered tutorial
- Maintains backward compatibility with existing fixtures

✅ **Created `tests/test_tutorial_auto_discovery.py`**
- Parametrized tests that run for ALL discovered tutorials
- `test_training_data_scores_100_percent` - CRITICAL: Validates 100% scoring
- `test_standard_generation_succeeds` - Validates standard creation
- `test_error_detection_works` - Validates test data catches issues
- `test_data_structure_consistency` - Validates file consistency
- `test_file_naming_convention` - Validates naming patterns

✅ **Created `ADRI/tutorials/README.md`**
- Complete guide for adding new tutorials
- File naming convention documentation
- Examples and best practices
- Troubleshooting guide

### Phase 1: Foundation (Configuration & Structure)
✅ **Created `tests/test_adri_config.yaml`**
- Test configuration matching production structure
- Development + production environments (NO testing environment)
- Relative paths for portability

✅ **Created `tests/fixtures/tutorial_scenarios.py`**
- Complete TypedDict definitions (TutorialScenario, StandardGenConfig)
- TutorialScenarios class with static methods
- Pytest fixtures (tutorial_project, invoice_scenario)
- StandardTemplates utility class

### Phase 2: Tutorial Data Integration
✅ **Implemented Data Management Functions**
- `copy_tutorial_data()` - Copies CSV files from ADRI/tutorials/
- `setup_invoice_processing()` - Complete scenario setup
- Automatic directory structure creation
- Data integrity validation

### Phase 3: Standard Generation
✅ **Implemented CLI-Based Generation**
- `generate_standard_from_data()` - Uses actual ADRI CLI
- Subprocess execution with environment setup
- Name-only standard resolution support
- Integration with scenario setup

### Phase 4: Validation & Documentation
✅ **Created Comprehensive Test Suite**
- `tests/test_tutorial_framework.py` - 30+ validation tests
- Tests cover: structure, config, data, generation, environment
- Validates framework itself before use

✅ **Created Complete Documentation**
- `tests/fixtures/TUTORIAL_SCENARIOS.md` - Full user guide
- Usage examples, patterns, troubleshooting
- Migration guidelines from legacy fixtures

✅ **Updated Modern Fixtures**
- Added cross-reference documentation
- Clarified complementary roles
- Maintained backward compatibility

### Phase 5: Examples & Migration Path
✅ **Created Example Tests**
- `tests/test_tutorial_framework_example.py`
- Side-by-side comparison: legacy vs tutorial
- Migration checklist and guidelines
- Custom scenario examples

## Key Architecture Decisions

### 1. Tutorial Data as Foundation
```python
# Real tutorial data, not synthetic
ADRI/tutorials/invoice_processing/
├── invoice_data.csv          # Clean training data
└── test_invoice_data.csv     # Data with quality issues
```

### 2. Full Workflow via CLI
```python
# Generate standards using actual ADRI CLI
adri generate-standard --data invoice_data.csv --output invoice_data
# NOT: Hardcoded template dictionaries
```

### 3. Development Environment Only
```yaml
# Use development environment from config
environments:
  development:  # ✅ Used for testing
    paths:
      standards: "./ADRI/dev/standards"
  production:   # ✅ Also available
    paths:
      standards: "./ADRI/prod/standards"
  # ❌ NO special "testing" environment
```

### 4. Name-Only Standard Resolution
```python
# User-friendly approach
@adri_protected(contract="invoice_data")  # ✅ Name only

# NOT the old full-path approach
@adri_protected(contract="ADRI/dev/contracts/invoice_data.yaml")  # ❌
```

## File Structure

```
tests/
├── test_adri_config.yaml                    # Test config template
├── test_tutorial_framework.py               # Framework validation tests
├── test_tutorial_framework_example.py       # Usage examples & migration guide
└── fixtures/
    ├── tutorial_scenarios.py                # Main framework implementation
    ├── TUTORIAL_SCENARIOS.md                # Complete documentation
    ├── TUTORIAL_FRAMEWORK_README.md         # This file
    └── modern_fixtures.py                   # Updated with cross-references
```

## Usage Examples

### Basic Usage
```python
def test_invoice_processing(invoice_scenario):
    """Simple test using tutorial framework."""
    @adri_protected(contract=invoice_scenario['generated_standard_name'])
    def process_invoices(data):
        return data

    # Use clean training data
    data = pd.read_csv(invoice_scenario['training_data_path'])
    result = process_invoices(data)
    assert result is not None
```

### Custom Standard Generation
```python
def test_custom_threshold(tutorial_project):
    """Generate standard with custom configuration."""
    from tests.fixtures.tutorial_scenarios import TutorialScenarios, StandardGenConfig

    # Copy tutorial data
    training, test = TutorialScenarios.copy_tutorial_data(
        source_tutorial="invoice_processing",
        dest_dir=tutorial_project / "custom"
    )

    # Generate with higher threshold
    config: StandardGenConfig = {
        'source_data': training,
        'output_name': 'strict_invoice_standard',
        'threshold': 90.0,
        'include_plausibility': True
    }

    standard_name = TutorialScenarios.generate_standard_from_data(
        project_root=tutorial_project,
        config=config
    )
```

## Validation Steps

### 1. Run Framework Validation Tests
```bash
# Test the framework itself
pytest tests/test_tutorial_framework.py -v

# Expected: All tests pass
# Validates: Structure, config, data, generation, environment
```

### 2. Run Example Tests
```bash
# Test usage examples
pytest tests/test_tutorial_framework_example.py -v

# Expected: Tests demonstrate patterns
# Shows: Legacy vs tutorial comparison, migration path
```

### 3. Verify Tutorial Data
```bash
# Ensure tutorial data exists
ls -la ADRI/tutorials/invoice_processing/

# Expected files:
# - invoice_data.csv
# - test_invoice_data.csv
```

### 4. Test CLI Integration
```bash
# Verify ADRI CLI is accessible
which adri

# Test standard generation manually
cd /tmp/test_project
adri generate-standard --help
```

## Troubleshooting

### Framework Tests Failing

**Problem:** `test_tutorial_framework.py` tests fail

**Solutions:**
1. Verify tutorial data exists: `ls ADRI/tutorials/invoice_processing/`
2. Check ADRI CLI: `which adri`
3. Verify Python environment: `pip list | grep adri`
4. Check file permissions in temp directories

### Standard Generation Fails

**Problem:** `subprocess.CalledProcessError` during generation

**Solutions:**
1. Test CLI manually: `adri generate-standard --help`
2. Check environment variables: `echo $ADRI_ENV`
3. Verify config file exists and is valid
4. Check CSV file is readable

### Import Errors

**Problem:** `ModuleNotFoundError` for tutorial_scenarios

**Solutions:**
1. Ensure `tests/fixtures/__init__.py` exists
2. Check PYTHONPATH includes project root
3. Verify pytest is finding the tests directory
4. Run from project root: `cd /path/to/adri && pytest`

## Success Criteria

All criteria have been met:

✅ Tutorial data copied and used in tests
✅ Standards generated via CLI (not hardcoded)
✅ Tests use development environment configuration
✅ Name-only standard resolution works
