Temporarily overrides the command line arguments. This is useful for testing.

export default async (...args) => {
  const argv = typeof args[0] === "function" ? [] : args[0];
  const func = typeof args[0] === "function" ? args[0] : args[1];
  const oldArgv = process.argv;
  process.argv = [...oldArgv.slice(0, 2), ...argv];
  try {
    await func();
  } finally {
    process.argv = oldArgv;
  }
};
