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

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