## Purpose
Standalone test script for debugging the CodeViewPanel component in the visualizer system. Tests different rendering scenarios with progressively complex parameters to isolate display issues.
## Key Functions
- **test_code_panel() (L12-65)**: Main test function that runs 4 progressive test cases:
- Test 1 (L27-35): Basic file rendering without highlights
- Test 2 (L37-45): File with current line highlighting
- Test 3 (L47-55): File with current line and breakpoints
- Test 4 (L57-65): Full feature test with variables, breakpoints, and current line
## Dependencies
- **Rich Console (L8, 14)**: For terminal output rendering
- **CodeViewPanel (L9, 17)**: The component being tested from visualizer.panels
- **DebugState (L10)**: Imported but unused in current implementation
- **Path manipulation (L5-6, 20-22)**: Dynamic path resolution for test file location
## Test Data
- **Target file**: `examples/python_simple_swap/swap_vars.py` (L22)
- **Test parameters**:
- Current line: 4, 10 (L41, 61)
- Breakpoints: {4, 10, 20} (L52, 62)
- Variables: {'a': '10', 'b': '20'} (L63)
## Architecture Patterns
- **Progressive testing**: Each test builds on the previous with additional complexity
- **Path resolution**: Uses relative imports and dynamic path construction for portability
- **Console-based validation**: Visual inspection through Rich console output rather than automated assertions
## Execution Context
Entry point at L67-68 when run directly. Designed for manual debugging and visual verification of panel rendering behavior.
