Test case:

var chai = require('chai');
chai.use(require('chai-fuzzy'));
var expect = chai.expect();

function Document() {}
var actual = new Document();
actual.foo = 1;
actual.bar = 2;
var expected = { foo: 1, bar: 2};
expect(actual).to.be.jsonOf(expected);

Expected: no error.

Actual:

      AssertionError: expected { Object (foo, bar, ...) } to be like JSON { Object (foo, bar, ...) }
      + expected - actual

Is this a bug? Is there a way to lossy compare just provided keys?

I had thought that this would be possible:

expect({ key1:0, key2:1 }).to.be.like({ key1:0 });

but it just seems to perform like deep.equal(), which is already provided by Mocha. I'm confused.

Edit: the functionality that I'd expected above in my code sample is made possible with chai-like.

At the top of the index.js (line 3), chai-fuzzy checks for the presence of "require" as a function. If it is not defined, it calls it anyway (line 32).

Look into a phantomjs runner for mocha and add that to the test makefile target

underscore is not listed on the dependencies of chai-fuzzy, only on devDependencies, so it fails unless underscore is added as a dependency of the parent project.

Todo: learn how hook into chai's chaining to allow something like:

expect(['a','b','c']).to.have.one.like('a');
expect({}).to.be.json.of({});

!!!

The current code for checking if the plugin is running in a browser or server-side only checks the types of a few different properties that are available in an application that uses require.js.

if (
  typeof require === "function"
  && typeof exports === "object"
  && typeof module === "object"
) {
  // server-side
  _ = require('underscore');
} else {
  // browser-side
  _ = window._;
}

It might be better to check for the existence of the "_" property on window first, then fall back to saying it's running on the server.

My setup could be a bit different than others as well, so please let me know if you need more information.
