code: function spawnProtractor(configPath, chunks, port, skyPagesConfig) {
    logger.info('Running Protractor');
    protractorLauncher.init(configPath, {
      params: {
        localUrl: `https://localhost:${port}`,

    });
    process.on('exit', killServers);
  }
docs: Spawns the protractor command.
  Perhaps this should be API driven?
