|
||||
enable_hdr_processing=True, # For HDR content
|
||||
|
||||
quality_preset="ultra" # Can now use "ultra" preset
|
||||
)
|
||||
|
||||
# Same processing call - just get more output formats
|
||||
result = await processor.process_video("input.mp4", "./output/")
|
||||
print(f"Generated formats: {list(result.encoded_files.keys())}")
|
||||
# Output: ['mp4', 'av1_mp4', 'hevc']
|
||||
```
|
||||
|
||||
### **Phase 3: Adaptive Streaming**
|
||||
|
||||
**Add streaming capabilities to existing workflows:**
|
||||
```python
|
||||
from video_processor.streaming import AdaptiveStreamProcessor
|
||||
|
||||
# Process video normally first
|
||||
processor = VideoProcessor(config)
|
||||
result = await processor.process_video("input.mp4", "./output/")
|
||||
|
||||
# Then create streaming package
|
||||
stream_processor = AdaptiveStreamProcessor(config)
|
||||
streaming_package = await stream_processor.create_adaptive_stream(
|
||||
video_path="input.mp4",
|
||||
output_dir="./streaming/",
|
||||
formats=["hls", "dash"]
|
||||
)
|
||||
|
||||
print(f"HLS playlist: {streaming_package.hls_playlist}")
|
||||
print(f"DASH manifest: {streaming_package.dash_manifest}")
|
||||
```
|
||||
|
||||
### **Phase 4: 360° Video Processing**
|
||||
|
||||
**Add 360° support (automatically detected):**
|
||||
```python
|
||||
# Enable 360° processing
|
||||
config = ProcessorConfig(
|
||||
# ... your existing settings ...
|
||||
enable_360_processing=True, # Default: auto-detected
|
||||
auto_detect_360=True, # Automatic detection
|
||||
generate_360_thumbnails=True # 360° specific thumbnails
|
||||
)
|
||||
|
||||
# Same processing call - automatically handles 360° videos
|
||||
processor = VideoProcessor(config)
|
||||
result = await processor.process_video("360_video.mp4", "./output/")
|
||||
|
||||
# Check if 360° video was detected
|
||||
if result.is_360_video:
|
||||
print(f"360° projection: {result.video_360.projection_type}")
|
||||
print(f"Spatial audio: {result.video_360.has_spatial_audio}")
|
||||
print(f"Recommended viewports: {len(result.video_360.optimal_viewports)}")
|
||||
|
||||
# Access 360° specific outputs
|
||||
print(f"360° thumbnails: {result.video_360.thumbnail_tracks}")
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🗄️ Database Migration
|
||||
|
||||
### **Procrastinate Task System Updates**
|
||||
|
||||
If you're using the Procrastinate task system, there are new database fields:
|
||||
|
||||
**Automatic Migration:**
|
||||
```bash
|
||||
# Migration is handled automatically when you upgrade
|
||||
uv run python -m video_processor.tasks.migration migrate
|
||||
|
||||
# Or use the enhanced migration system
|
||||
from video_processor.tasks.migration import ProcrastinateMigrator
|
||||
|
||||
migrator = ProcrastinateMigrator(db_url)
|
||||
await migrator.migrate_to_latest()
|
||||
```
|
||||
|
||||
**New Database Fields (Added Automatically):**
|
||||
- `quality_analysis`: JSON field for AI analysis results
|
||||
- `is_360_video`: Boolean for 360° video detection
|
||||
- `video_360_metadata`: JSON field for 360° specific data
|
||||
- `streaming_outputs`: JSON field for streaming package info
|
||||
|
||||
### **Worker Compatibility**
|
||||
|
||||
**Backward Compatible**: Existing workers continue to work with new tasks:
|
||||
|
||||
```python
|
||||
# Existing workers automatically support new features
|
||||
# No code changes required in worker processes
|
||||
|
||||
# But you can enable enhanced processing:
|
||||
from video_processor.tasks.enhanced_worker import EnhancedWorker
|
||||
|
||||
# Enhanced worker with all new features
|
||||
worker = EnhancedWorker(
|
||||
enable_ai_analysis=True,
|
||||
enable_360_processing=True,
|
||||
enable_advanced_codecs=True
|
||||
)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## ⚠️ Breaking Changes (Minimal)
|
||||
|
||||
### **None for Basic Usage**
|
||||
- ✅ All existing APIs work unchanged
|
||||
- ✅ Configuration is backward compatible
|
||||
- ✅ Database migrations are automatic
|
||||
- ✅ Workers continue functioning normally
|
||||
|
||||
### **Optional Breaking Changes (Advanced Usage)**
|
||||
|
||||
**1. Custom Encoder Implementations**
|
||||
If you've implemented custom encoders, you may want to update them:
|
||||
|
||||
```python
|
||||
# Before (still works)
|
||||
class CustomEncoder:
|
||||
def encode_video(self, input_path, output_path, options):
|
||||
# Your implementation
|
||||
pass
|
||||
|
||||
# After (enhanced with new features)
|
||||
class CustomEncoder:
|
||||
def encode_video(self, input_path, output_path, options):
|
||||
# Your implementation
|
||||
pass
|
||||
|
||||
# Optional: Add support for new codecs
|
||||
def supports_av1(self):
|
||||
return False # Override if you support AV1
|
||||
|
||||
def supports_hevc(self):
|
||||
return False # Override if you support HEVC
|
||||
```
|
||||
|
||||
**2. Custom Storage Backends**
|
||||
Custom storage backends gain new optional methods:
|
||||
|
||||
```python
|
||||
# Before (still works)
|
||||
class CustomStorageBackend:
|
||||
def store_file(self, source, destination):
|
||||
# Your implementation
|
||||
pass
|
||||
|
||||
# After (optional enhancements)
|
||||
class CustomStorageBackend:
|
||||
def store_file(self, source, destination):
|
||||
# Your implementation
|
||||
pass
|
||||
|
||||
# Optional: Handle 360° specific files
|
||||
def store_360_files(self, files_dict, base_path):
|
||||
# Default implementation calls store_file for each
|
||||
for name, path in files_dict.items():
|
||||
self.store_file(path, base_path / name)
|
||||
|
||||
# Optional: Handle streaming manifests
|
||||
def store_streaming_package(self, package, base_path):
|
||||
# Default implementation available
|
||||
pass
|
||||
```
|
||||
|
||||

## 🎯 Recommended Migration Path
|
||||
|
||||
### **Step 1: Update Dependencies**
|
||||
```bash
|
||||
# Update to latest version
|
||||
uv add video-processor
|
||||
|
||||
# Install optional dependencies for features you want
|

logging.basicConfig(level=logging.INFO)
|
||||
```
|
||||
|
||||
### **Step 3: Enable New Features Gradually**
|
||||
```python
|
||||
# Start with AI analysis (most universal benefit)
|
||||
config.enable_ai_analysis = True
|
||||
|
||||
# Add advanced codecs if you need better compression
|
||||
config.enable_av1_encoding = True
|
||||
config.output_formats.append("av1_mp4")
|
||||
|
||||
# Enable 360° if you process immersive videos
|
||||
config.enable_360_processing = True
|
||||
|
||||
# Add streaming for web delivery
|
||||
# (Separate API call - doesn't change existing workflow)
|
||||
```
|
||||
|
||||
### **Step 4: Update Your Code to Use New Features**
|
||||
```python
|
||||
# Take advantage of new analysis results
|
||||
if result.quality_analysis:
|
||||
# Use AI-recommended thumbnails
|
||||
best_thumbnails = result.quality_analysis.recommended_thumbnails
|
||||
|
||||
if result.is_360_video:
|
||||
# Handle 360° specific outputs
|
||||
projection = result.video_360.projection_type
|
||||
viewports = result.video_360.optimal_viewports
|
||||
```
|
||||
|
||||
This migration maintains **100% backward compatibility** while giving you access to cutting-edge video processing capabilities. Your existing code continues working while you gradually adopt new features at your own pace.

# Advanced Video Features Documentation
|
||||
|
||||
This document comprehensively details the advanced video processing capabilities already implemented in the video-processor library.
|
||||
|
||||
## 🎬 360° Video Processing Capabilities
|
||||
|
||||
### Core 360° Detection System (`src/video_processor/utils/video_360.py`)
|
||||
|
||||
**Sophisticated Multi-Method Detection**
|
||||
- **Spherical Metadata Detection**: Reads Google/YouTube spherical video standard metadata tags
|
||||
- **Aspect Ratio Analysis**: Detects equirectangular videos by 2:1 aspect ratio patterns
|
||||
- **Filename Pattern Recognition**: Identifies 360° indicators in filenames ("360", "vr", "spherical", etc.)
|
||||
- **Confidence Scoring**: Provides confidence levels (0.6-1.0) for detection reliability
|
||||
|
||||
**Supported Projection Types**
|
||||
- `equirectangular` (most common, optimal for VR headsets)
|
||||
- `cubemap` (6-face projection, efficient encoding)
|
||||
- `cylindrical` (partial 360°, horizontal only)
|
||||
- `stereographic` ("little planet" effect)
|
||||
|
||||
**Stereo Mode Support**
|
||||
- `mono` (single eye view)
|
||||
- `top-bottom` (3D stereoscopic, vertical split)
|
||||
- `left-right` (3D stereoscopic, horizontal split)
|
||||
|
||||
### Advanced 360° Thumbnail Generation (`src/video_processor/core/thumbnails_360.py`)

||||
- **Mathematical Projections**: Implements perspective and stereographic coordinate transformations
|
||||
- **OpenCV Integration**: Uses cv2.remap for efficient image warping
|
||||
- **Ray Casting**: 3D ray direction calculations for accurate perspective views
|
||||
- **Spherical Coordinate Conversion**: Converts between Cartesian and spherical coordinate systems
|
||||
|
||||
**360° Sprite Sheet Generation**
|
||||

|
||||
- **WebVTT Integration**: Generates thumbnail preview files for video players
|
||||
- **Batch Processing**: Efficiently processes multiple timestamps for sprite creation
|
||||
|
||||
### Intelligent Bitrate Optimization
|
||||
|
||||
**Projection-Aware Bitrate Multipliers**
|
||||
```python
|
||||
multipliers = {
|
||||
"equirectangular": 2.5, # Most common, needs high bitrate due to pole distortion
|
||||
"cubemap": 2.0, # More efficient encoding, less distortion
|
||||
"cylindrical": 1.8, # Less immersive, lower multiplier acceptable
|
||||
"stereographic": 2.2, # Good balance for artistic effect
|
||||
"unknown": 2.0, # Safe default
|
||||
}
|
||||
```
|
||||
|
||||
**Optimal Resolution Recommendations**
|
||||
- **Equirectangular**: 2K (1920×960) up to 8K (7680×3840)
|
||||
- **Cubemap**: 1.5K to 4K per face
|
||||
- **Automatic Resolution Selection**: Based on projection type and quality preset
|
||||
|
||||
## 🎯 Advanced Encoding System (`src/video_processor/core/encoders.py`)
|
||||
|
||||
### Multi-Pass Encoding Architecture
|
||||
|
||||
**MP4 Two-Pass Encoding**
|
||||

||||
|
||||
**OGV Theora Encoding**
|
||||
- **Single-Pass Efficiency**: Optimized for legacy browser support
|
||||
- **Quality Scale**: Uses qscale for balanced quality/size ratio
|
||||
|
||||
### Advanced Quality Presets

# Install FFmpeg (varies by OS)
|
||||
# Ubuntu/Debian: sudo apt install ffmpeg
|
||||
# macOS: brew install ffmpeg
|
||||
# Windows: Download from ffmpeg.org
|
||||
```
|
||||
|
||||

# Video Processor Testing Framework
|
||||
|
||||
A comprehensive, modern testing framework specifically designed for video processing applications with beautiful HTML reports, quality metrics, and advanced categorization.
|
||||
|
||||
## 🎯 Overview
|
||||
|
||||
This testing framework provides:
|
||||
|
||||
- **Advanced Test Categorization**: Automatic organization by type (unit, integration, performance, 360°, AI, streaming)
|
||||
- **Quality Metrics Tracking**: Comprehensive scoring system for test quality assessment
|
||||
- **Beautiful HTML Reports**: Modern, responsive reports with video processing themes
|
||||
- **Parallel Execution**: Smart parallel test execution with resource management
|
||||
- **Fixture Library**: Extensive fixtures for video processing scenarios
|
||||
- **Custom Assertions**: Video-specific assertions for quality, performance, and output validation
|
||||
|
||||
## 🚀 Quick Start
|
||||
|
||||
### Installation
|
||||
|
||||
```bash
|
||||
# Install with enhanced testing dependencies
|
||||
uv sync --dev
|
||||
```
|
||||
|
||||
### Running Tests
|
||||
|
||||
```bash
|
||||
# Quick smoke tests (fastest)
|
||||
make test-smoke
|
||||
# or
|
||||
python run_tests.py --smoke
|
||||
|
||||
# Unit tests with quality tracking
|
||||
make test-unit
|
||||
# or
|
||||
python run_tests.py --unit
|
||||
|
||||
# All tests with comprehensive reporting
|
||||
make test-all
|
||||
# or
|
||||
python run_tests.py --all
|
||||
```
|
||||
|
||||
### Basic Test Example
|
||||
|
||||
```python
|
||||
import pytest
|
||||
|
||||
@pytest.mark.unit
|
||||
def test_video_encoding(enhanced_processor, quality_tracker, video_assert):
|
||||
"""Test video encoding with quality tracking."""
|
||||
# Your test logic here
|
||||
result = enhanced_processor.encode_video(input_path, output_path)
|
||||
|
||||
# Record quality metrics
|
||||
quality_tracker.record_assertion(result.success, "Encoding completed")
|
||||
quality_tracker.record_video_processing(
|
||||
input_size_mb=50.0,
|
||||
duration=2.5,
|
||||
output_quality=8.5
|
||||
)
|
||||
|
||||
# Use custom assertions
|
||||
video_assert.assert_video_quality(result.quality_score, 7.0)
|
||||
video_assert.assert_encoding_performance(result.fps, 10.0)
|
||||
```
|
||||
|
||||
## 📊 Test Categories
|
||||
|
||||
### Automatic Categorization
|
||||
|
||||
Tests are automatically categorized based on:
|
||||
|
||||
- **File Location**: `/unit/`, `/integration/`, etc.
|
||||
- **Test Names**: Containing keywords like `performance`, `360`, `ai`
|
||||
- **Markers**: Explicit `@pytest.mark.category` decorators
|
||||
|
||||
### Available Categories
|
||||
|
||||
| Category | Marker | Description |
|
||||
|----------|--------|-------------|
|
||||
| Unit | `@pytest.mark.unit` | Individual component tests |
|
||||
| Integration | `@pytest.mark.integration` | Cross-component tests |
|
||||
| Performance | `@pytest.mark.performance` | Benchmark and performance tests |
|
||||
| Smoke | `@pytest.mark.smoke` | Quick validation tests |
|
||||
| 360° Video | `@pytest.mark.video_360` | 360° video processing tests |
|
||||
| AI Analysis | `@pytest.mark.ai_analysis` | AI-powered analysis tests |
|
||||
| Streaming | `@pytest.mark.streaming` | Adaptive bitrate and streaming tests |
|
||||
|
||||
### Running Specific Categories
|
||||
|
||||
```bash
|
||||
# Run only unit tests
|
||||
python run_tests.py --category unit
|
||||
|
||||
# Run multiple categories
|
||||
python run_tests.py --category unit integration
|
||||
|
||||
# Run performance tests with no parallel execution
|
||||
python run_tests.py --performance --no-parallel
|
||||
|
||||
# Run tests with custom markers
|
||||
python run_tests.py --markers "not slow and not gpu"
|
||||
```
|
||||
|
||||
## 🧪 Fixtures Library
|
||||
|
||||
### Enhanced Core Fixtures
|
||||
|
||||
```python
|
||||
def test_with_enhanced_fixtures(
|
||||
enhanced_temp_dir, # Structured temp directory
|
||||
video_config, # Test-optimized processor config
|
||||
enhanced_processor, # Processor with test settings
|
||||
quality_tracker # Quality metrics tracking
|
||||
):
|
||||
# Test implementation
|
||||
pass
|
||||
```
|
||||
|
||||
### Video Scenario Fixtures
|
||||
|
||||
```python
|
||||
def test_video_scenarios(test_video_scenarios):
|
||||
"""Pre-defined video test scenarios."""
|
||||
standard_hd = test_video_scenarios["standard_hd"]
|
||||
assert standard_hd["resolution"] == "1920x1080"
|
||||
assert standard_hd["quality_threshold"] == 8.0
|
||||
```
|
||||
|
||||
### Performance Benchmarks
|
||||
|
||||
```python
|
||||
def test_performance(performance_benchmarks):
|
||||
"""Performance thresholds for different operations."""
|
||||
h264_720p_fps = performance_benchmarks["encoding"]["h264_720p"]
|
||||
assert encoding_fps >= h264_720p_fps
|
||||
```
|
||||
|
||||
### Specialized Fixtures
|
||||
|
||||
```python
|
||||
# 360° video processing
|
||||
def test_360_video(video_360_fixtures):
|
||||
equirect = video_360_fixtures["equirectangular"]
|
||||
cubemap = video_360_fixtures["cubemap"]
|
||||
|
||||
# AI analysis
|
||||
def test_ai_features(ai_analysis_fixtures):
|
||||
scene_detection = ai_analysis_fixtures["scene_detection"]
|
||||
object_tracking = ai_analysis_fixtures["object_tracking"]
|
||||
|
||||
# Streaming
|
||||
def test_streaming(streaming_fixtures):
|
||||
adaptive = streaming_fixtures["adaptive_streams"]
|
||||
live = streaming_fixtures["live_streaming"]
|
||||
```
|
||||
|
||||
## 📈 Quality Metrics
|
||||
|
||||
### Automatic Tracking
|
||||
|
||||
The framework automatically tracks:
|
||||
|
||||
- **Functional Quality**: Assertion pass rates, error handling
|
||||
- **Performance Quality**: Execution time, memory usage
|
||||
- **Reliability Quality**: Error frequency, consistency
|
||||
- **Maintainability Quality**: Test complexity, documentation
|
||||
|
||||
### Manual Recording

||||
```python
|
||||
def test_with_quality_tracking(quality_tracker):
|
||||
# Record assertions
|
||||
quality_tracker.record_assertion(True, "Basic validation passed")
|
||||
quality_tracker.record_assertion(False, "Expected edge case failure")
|
||||
|
||||
# Record warnings and errors
|
||||
quality_tracker.record_warning("Non-critical issue detected")
|
||||
quality_tracker.record_error("Critical error occurred")
|
||||
|
||||
# Record video processing metrics
|
||||
quality_tracker.record_video_processing(
|
||||
input_size_mb=50.0,
|
||||
duration=2.5,
|
||||
output_quality=8.7
|
||||
)
|
||||
```
|
||||
|
||||
### Quality Scores
|
||||
|
||||
- **0-10 Scale**: All quality metrics use 0-10 scoring
|
||||
- **Letter Grades**: A+ (9.0+) to F (< 4.0)
|
||||
- **Weighted Overall**: Combines all metrics with appropriate weights
|
||||
- **Historical Tracking**: SQLite database for trend analysis
|
||||
|
||||

|
||||
|
||||
## 🔧 Custom Assertions
|
||||
|
||||
### Video Quality Assertions
|
||||
|
||||
```python
|
||||
def test_video_output(video_assert):
|
||||
# Quality threshold testing
|
||||
video_assert.assert_video_quality(8.5, min_threshold=7.0)
|
||||
|
||||
# Performance validation
|
||||
video_assert.assert_encoding_performance(fps=15.0, min_fps=10.0)
|
||||
|
||||
# File size validation
|
||||
video_assert.assert_file_size_reasonable(45.0, max_size_mb=100.0)
|
||||
|
||||
# Duration preservation
|
||||
video_assert.assert_duration_preserved(
|
||||
input_duration=10.0,
|
||||
output_duration=10.1,
|
||||
tolerance=0.1
|
||||
)
|
||||
```
|
||||
|
||||
## ⚡ Parallel Execution
|
||||
|
||||
### Configuration
|
||||
|
||||
```bash
|
||||
# Auto-detect CPU cores
|
||||
python run_tests.py --unit -n auto
|
||||
|
||||
# Specific worker count
|
||||
python run_tests.py --unit --workers 8
|
||||
|
||||
# Disable parallel execution
|
||||
python run_tests.py --unit --no-parallel
|
||||
```
|
||||
|
||||
### Best Practices
|
||||
|
||||
- **Unit Tests**: Safe for parallel execution
|
||||
- **Integration Tests**: Often need isolation (--no-parallel)
|
||||
- **Performance Tests**: Require isolation for accurate measurements
|
||||
- **Resource-Intensive Tests**: Limit workers to prevent resource exhaustion
|
||||
|
||||
## 🐳 Docker Integration
|
||||
|
||||
### Running in Docker
|
||||
|
||||
```bash
|
||||
# Build test environment
|
||||
make docker-build
|
||||
|
||||
# Run tests in Docker
|
||||
make docker-test
|
||||
|
||||
# Integration tests with Docker
|
||||
make test-integration
|
||||
```
|
||||
|
||||
### CI/CD Integration
|
||||
|
||||
```yaml
|
||||
# GitHub Actions example
|
||||
- name: Run Video Processor Tests
|
||||
run: |
|
||||
uv sync --dev
|
||||
python run_tests.py --all --no-parallel
|
||||
|
||||
- name: Upload Test Reports
|
||||
uses: actions/upload-artifact@v3
|
||||
with:
|
||||
name: test-reports
|
||||
path: test-reports/
|
||||
```
|
||||
|
||||
## 📝 Configuration
|
||||
|
||||
### Environment Variables
|
||||
|
||||
```bash
|
||||
# Test execution
|
||||
TEST_PARALLEL_WORKERS=4 # Number of parallel workers
|
||||
TEST_TIMEOUT=300 # Test timeout in seconds
|
||||
TEST_FAIL_FAST=true # Stop on first failure
|
||||
|
||||
# Reporting
|
||||
TEST_REPORTS_DIR=./test-reports # Report output directory
|
||||
MIN_COVERAGE=80.0 # Minimum coverage percentage
|
||||
|
||||
# CI/CD
|
||||
CI=true # Enable CI mode (shorter output)
|
||||
```
|
||||
|
||||
### pyproject.toml Configuration
|
||||
|
||||
The framework integrates with your existing `pyproject.toml`:
|
||||
|
||||
```toml
|
||||
[tool.pytest.ini_options]
|
||||
addopts = [
|
||||
"-v",
|
||||
"--strict-markers",
|
||||
"-p", "tests.framework.pytest_plugin",
|
||||
]
|
||||
|
||||
markers = [
|
||||
"unit: Unit tests for individual components",
|
||||
"integration: Integration tests across components",
|
||||
"performance: Performance and benchmark tests",
|
||||
# ... more markers
|
||||
]
|
||||
```
|
||||
|
||||
## 🔍 Advanced Usage
|
||||
|
||||
### Custom Test Runners
|
||||
|
||||
```python
|
||||
from tests.framework import TestingConfig, HTMLReporter
|
||||
|
||||
# Custom configuration
|
||||
config = TestingConfig(
|
||||
parallel_workers=8,
|
||||
theme="custom-dark",
|
||||
enable_test_history=True
|
||||
)
|
||||
|
||||
# Custom reporter
|
||||
reporter = HTMLReporter(config)
|
||||
```
|
||||
|
||||
### Integration with Existing Tests
|
||||
|
||||
The framework is designed to be backward compatible:
|
||||
|
||||
```python
|
||||
# Existing test - no changes needed
|
||||
def test_existing_functionality(temp_dir, processor):
|
||||
# Your existing test code
|
||||
pass
|
||||
|
||||
# Enhanced test - use new features
|
||||
@pytest.mark.unit
|
||||
def test_with_enhancements(enhanced_processor, quality_tracker):
|
||||
# Enhanced test with quality tracking
|
||||
pass
|
||||
```
|
||||
|
||||
### Database Tracking
|
||||
|
||||
```python
|
||||
from tests.framework.quality import TestHistoryDatabase
|
||||
|
||||
# Query test history
|
||||
db = TestHistoryDatabase()
|
||||
history = db.get_test_history("test_encoding", days=30)
|
||||
trends = db.get_quality_trends(days=30)
|
||||
```
|
||||
|
||||
## 🛠️ Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Tests not running with framework**
|
||||
```bash
|
||||
# Ensure plugin is loaded
|
||||
pytest --trace-config | grep "video_processor_plugin"
|
||||
```
|
||||
|
||||
**Import errors**
|
||||
```bash
|
||||
# Verify installation
|
||||
uv sync --dev
|
||||
python -c "from tests.framework import HTMLReporter; print('OK')"
|
||||
```
|
||||
|
||||
**Reports not generating**
|
||||
```bash
|
||||
# Check permissions and paths
|
||||
ls -la test-reports/
|
||||
mkdir -p test-reports
|
||||
```
|
||||
|
||||
### Debug Mode
|
||||
|
||||
```bash
|
||||
# Verbose output with debug info
|
||||
python run_tests.py --unit --verbose
|
||||
|
||||
# Show framework configuration
|
||||
python -c "from tests.framework.config import config; print(config)"
|
||||
```
