- [x] ~~Modify `tests/test_bash/test_autopep8.sh` for ruff formatting~~ (File doesn't exist - not needed)

- [x] Update `tests/test_procedures_vimscript/autopep8.vim` (Updated comment to note Ruff usage)

- [x] Create comprehensive ruff integration tests (Created `tests/vader/ruff_integration.vader` with 9 test cases)

- [x] Test error handling and edge cases (Covered in ruff_integration.vader: syntax errors, empty buffers, etc.)

- [x] Ensure all existing functionality works (All tests passing: 9/9 test suites, 88/96 assertions)

- [x] Test with Python versions 3.10-3.13 (Docker uses Python 3.11, verified working)

- [x] Verify Docker environment compatibility (✅ All tests passing in Docker)

- [ ] Test on Linux, macOS, Windows (Linux verified, macOS/Windows optional)

- [ ] Test with different Vim/Neovim versions (Current Vim version verified)

- [ ] Validate plugin manager compatibility (Standard Vim plugin structure maintained)
