How do I setup Testling-CI with QUnit + QUnit-TAP?

Problem

We are trying to setup Testling to run our QUnit (with QUnit-TAP) tests following the "Custom Libraries" instructions: http://ift.tt/1IMJl9J

Our testling configuration (in package.json file) is:

"testling": {
  "html": "test.html",
  "browsers": [
    "ie/6..latest",
    "chrome/22..latest",
    "firefox/16..latest",
    "safari/latest",
    "opera/11.0..latest",
    "iphone/6",
    "ipad/6",
    "android-browser/latest"
  ]
}

Full package.json: http://git.io/vT3s7

and we setup the WebHook as per the quick start instructions:

But when we push to the repo the WebHook fails.
The payload is quite long. see: http://git.io/vT33D

Our tests work in the browser. See: http://ift.tt/1IMJl9N
(open devtools/console to) see the the Valid TAP output:

Any help much appreciated!

• We followed the instructions in the quick start guide: http://ift.tt/1eoDoOe
• But we are using QUnit in our project(s) so we followed the "Custom Libraries" instructions: http://ift.tt/1IMJl9J
