`tape-six-proc` is a command‑line helper for the `tape-six` testing framework that runs each test file in its own subprocess instead of using worker threads, giving full process isolation and preventing shared‑state leaks. It works out‑of‑the‑box on Node, Deno and Bun and can execute TypeScript test files natively without any transpilation step, making it ideal for JavaScript/TypeScript projects that need reliable, cross‑runtime testing.
