An example of using chef-zero for integration testing chef-node

nodes.js

var spawn = require('child_process').spawn,

      if (code !== 0) { throw new Error('Chef Zero exited unexpectedly.'); }
    });
    chefZero.stdout.on('data', function (data) {
      if (data.toString().indexOf('is listening at') !== -1) {
        chefZero.emit('ready');
      }
