# Utils Module

Utility modules organized into logical subdirectories for maintainability and scalability.

## Usage

### From Extended Test Base Classes

Both `BenchmarkBase` and `FunctionalBase` inherit from `ExtendedTestBase`, which provides
shared infrastructure (command execution, config loading, result creation, statistics, uploads):

```python
# In benchmark_base.py / functional_base.py
from utils.extended_test_base import ExtendedTestBase


class BenchmarkBase(ExtendedTestBase): ...


class FunctionalBase(ExtendedTestBase): ...
```

### From Test Scripts

Test scripts add `extended_tests/` to `sys.path`, then import:

```python
# Import path setup (already done in base classes)
sys.path.insert(
    0, str(Path(__file__).resolve().parents[2])
)  # Adds extended_tests/ to path

# Core utilities
from utils.logger import log
from utils.constants import Constants
from utils.exceptions import ConfigurationError

# Main API classes
from utils.extended_test_base import ExtendedTestBase
from utils.extended_test_client import ExtendedTestClient
from utils.system.system_detector import SystemDetector
from utils.config.config_helper import ConfigHelper
from utils.results.results_handler import ResultsHandler
```

### Subdirectory Imports

```python
# Configuration
from utils.config import ConfigHelper, ConfigParser, ConfigValidator

# System detection
from utils.system import (
    SystemDetector,
    HardwareDetector,
    ROCmDetector,
    PlatformDetector,
)

# Results handling
from utils.results import ResultsHandler, ResultsAPI
```

## Modules

### Root Level

- **extended_test_base.py** - `ExtendedTestBase` shared base class for benchmark and functional tests (config loading, command execution, ROCm env setup, test result creation, statistics, result uploads)
- **extended_test_client.py** - `ExtendedTestClient` API for system detection and result reporting
- **constants.py** - Framework constants and defaults
- **exceptions.py** - Custom exception classes
- **logger.py** - Logging configuration

### Config

Configuration loading, parsing, and validation.

- **config_helper.py** - High-level config utilities
- **config_parser.py** - YAML parser with environment variable expansion
- **config_validator.py** - JSON Schema validation

### System

Platform, hardware, and ROCm detection.

- **system_detector.py** - Main orchestrator
- **hardware.py** - CPU and GPU detection
- **platform.py** - OS, kernel, SBIOS detection
- **rocm_detector.py** - ROCm version and build info

### Results

Test results formatting, saving, and API submission.

- **results_handler.py** - Results formatting and local saving
- **results_api.py** - REST API client

## Adding New Modules

### To Existing Subdirectory

1. Create file in appropriate subdirectory
1. Add exports to subdirectory's `__init__.py`
1. Optionally add to `utils/__init__.py` for backward compatibility

### New Subdirectory

1. Create directory with `__init__.py`
1. Add modules
1. Update `utils/__init__.py` for commonly used classes

## Testing

```bash
# Run from project root
cd /path/to/TheRock

# Run a benchmark test (imports are handled internally)
python tests/extended_tests/benchmark/scripts/test_rocfft_benchmark.py

# Verify utils imports work
cd tests/extended_tests
python -c "from utils.logger import log; print('Utils imports working')"
```
