Setup karma unit tests with pouchdb

This is a common error: PhantomJS has not implemented Function.prototype.bind (here's the bug), so you need the es5-shim.

Or you can get by by just shimming Function.prototype.bind instead of including the whole es5-shim library. Here's an example (taken from here):

(function () {  'use strict';  // minimal polyfill for phantomjs; in the future, we should do ES5_SHIM=true like pouchdb  if (!Function.prototype.bind) {    Function.prototype.bind = function (oThis) {      if (typeof this !== "function") {        // closest thing possible to the ECMAScript 5        // internal IsCallable function        throw new TypeError("Function.prototype.bind - what is trying to be bound is not callable");      }      var aArgs = Array.prototype.slice.call(arguments, 1),          fToBind = this,          fNOP = function () {},          fBound = function () {            return fToBind.apply(this instanceof fNOP && oThis                   ? this                   : oThis,                   aArgs.concat(Array.prototype.slice.call(arguments)));          };      fNOP.prototype = this.prototype;      fBound.prototype = new fNOP();      return fBound;    };  }})();

The issue is fixed in PhantomJS 2+. So an update of the Phantom node modules should do it.

Tested with the following versions of test-related modules in package.json

"karma": "0.13.21","karma-jasmine": "0.3.7","karma-phantomjs-launcher": "1.0.0","phantomjs-prebuilt": "2.1.3",
