Code Tester Tool - Run tests với nhiều frameworks.
Author: Hieu Louis (2026)
Frameworks:
- pytest : pytest -v <path>
- unittest : python3 -m unittest -v <path>
- jest : npx jest <path>
- go : go test -v <path>
- cargo : cargo test <path>
- rspec : rspec <path>
Auto-detect framework dựa trên config files (pyproject.toml, go.mod,
Cargo.toml, package.json, Gemfile) hoặc file extensions.
DANGEROUS (executes test commands), requires_confirmation.
