| /** | ||
| * This module is used as an entry point for test files utilizing the cluster | ||
| * module which forks processes and cannot use `.ts` files due to | ||
| * incompatibility with Deno's Node module resolution. | ||
| * See https://github.com/denoland/deno/blob/main/cli/node/mod.rs#L725 | ||
| * | ||
| * The idea is to emulate a CommonJS environment without having to modify | ||
| * the test files in any way | ||
| * | ||
| * Running with all permissions and unstable is recommended | ||
| * | ||
| * Usage: `deno run -A --unstable require.mjs my_commonjs_file.js` | ||
