testing-patterns

This file is a benign unified test runner that detects Node or Python projects, constructs standard test or coverage commands, executes them via subprocess.run (without shell=True), captures outputs, and emits a summary JSON and exit code. There is no direct evidence of embedded malware, obfuscation, or credential harvesting in this module. The main security risk is operational: executing project tests will run arbitrary code from the repository and any invoked tooling (npm/npx) — a typical supply-chain execution risk. Recommendation: only run against trusted repositories or within strict isolation (container/VM/sandbox), avoid running on untrusted checkouts, and consider adding explicit sandboxing, better error handling, and warnings in the script.
