How to use the one-time/async function in one-time

async function intercept({ send }) {
  const ocm = ['log', 'info', 'warn', 'error'];
  const oc = {};

  ocm.forEach(function each(method) {
    oc[method] = console[method];
    console[method] = send.bind(send, `console.${method}`);
  });

  return once(async function after() {
    ocm.forEach(function each(method) {
      console[method] = oc[method];
      delete oc[method];
    });
  });
}

complete() {
    return once(async function completed(err) {
      debug('completed the run', err);

      if (err) {
        if (typeof err === 'number') {
          err = new Error(`Test are failing with exit code ${err}`);
        }

        this.subway.send('complete', failure(err));
      } else {
        this.subway.send('complete');
      }

      await this.teardown();
    }.bind(this));
  }
