soda and chrome browser

How to run chrome in selenium soda test?

When I set browser: "chrome" it opens firefox anyway. 

browser = soda.createClient({
    host: "localhost",
    port: 4444,
    url: "http://localhost:3000",
    browser: "chrome"
 });

This method dont even executes:

browser = soda.createClient({
   host: "localhost",
   port: 4444,
   url: "http://localhost:3000",
   browser: "custom /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome"
});

As per the documentation, use googlechrome instead of chrome

var soda = require('soda');

var browser = soda.createSauceClient({
  'url': 'http://yourwebsite/'
, 'username': ''
, 'access-key': ''
, 'os': 'Windows 2003'
, 'browser': 'googlechrome'
, 'max-duration': 300
});

See http://learnboost.github.io/soda/ for more details. In fact, the example I have provided is from their website. Also, you could try *chrome or *google, since that seems to be supported functionality.
