nightwatch/lib/runner/concurrency/task.js

Easy to use Node.js based end-to-end testing solution for web applications using the W3C WebDriver API.

const Nightwatch = require('../../index');
function runWorkerTask({argv, port1}) {
  const writeData = (data) => {
    data = data.toString().trim();

    if (data){
      port1.postMessage({
        type: 'stdout',
        data: data
      });
    }
  };

  process.stdout.write = writeData;
  process.stderr.write = writeData;

  //send reports to main thread using message port
  process.port = port1;

  return Nightwatch.runTests(argv, {});
}

module.exports = runWorkerTask;
