Prevent zombie.js from loading only external resources

Question

I am using zombie.js to load a page from a local express server during a test. Unfortunately, there is a script element which calls out to Google Analytics. I would like to block this external script (gracefully) without preventing other (local) scripts from loading, if possible.

I know that { runScripts : false } is available with calls to browser.visit(). However, that refuses to load any and all scripts on the page, not just those living on other hosts. Is this possible?

Answer 1

Since zombie 3.1, the browser.resources.mock method is gone. The alternative is to use nock library:

var nock = require('nock')

nock('http://www.google-analytics.com')
  .get('/analytics.js')
  .times(Math.Infinity)
  .reply(200, '{}')

var Browser = require('zombie')
var browser = new Browser()

Answer 2

You should use the resources object.

You can set certain requests to give specific responses if you don't want the request to actually go through. You'd do the following to make google analytics return an empty document:

browser.resources.mock('http://google.com/url/to/analytics.js',{});

Note that you have to provide the exact URL that you want to mock, there is no way to mock a partial URL such as a domain name.
