# NeuroSAM 3 Test Suite

Comprehensive test suite for NeuroSAM 3 application.

## Running Tests

Run all tests:
```bash
python -m pytest tests/
```

Run specific test file:
```bash
python -m pytest tests/test_validators.py
python -m pytest tests/test_segmentation.py
python -m pytest tests/test_cache_manager.py
```

Run with verbose output:
```bash
python -m pytest tests/ -v
```

## Test Coverage

### test_validators.py
- File path validation
- File size validation
- File extension validation
- Threshold validation
- Coordinate validation
- Bounding box validation
- Number of masks validation
- Prompt text validation
- Modality validation
- Transparency validation
- Brightness/contrast validation

### test_segmentation.py
- Dice score calculation
- IoU score calculation
- Grid point generation
- ROI statistics formatting

### test_cache_manager.py
- Cache set/get operations
- Cache size limits
- LRU eviction policy
- TTL expiration
- Cache clearing
- Cache statistics

## Adding New Tests

When adding new functionality, create corresponding test files following the naming convention:
- `test_<module_name>.py` for module tests
- Use unittest.TestCase for test classes
- Follow AAA pattern: Arrange, Act, Assert

## Requirements

Tests require:
- pytest (optional, can use unittest)
- numpy
- PIL/Pillow

Install test dependencies:
```bash
pip install pytest pytest-cov
```
