Yes, Sinon is mostly concerned with functions, as I believe that's the right level to stub/mock at in JavaScript (building objects of stub methods is very simple, and no tools is needed). There are a few exceptions, e.g. sinon.stub(obj); will stub all methods on that object.
Relevant to your situation however, is a new feature since 1.1.0. Sandboxed stubs can override properties:
this.example("assert is a reference to nodespec.assert", sinon.test(function() {
var fake_assert = new Object;
this.stub(require('../lib/index'), "assert", fake_assert);
real_assert.strictEqual(this.context.assert, fake_assert);
this.done();
}));
That should work - this.stub(obj, prop) - allows you to replace the property with another property, and the sandbox context will automatically revert it for you. Outside the sandbox there's no point in Sinon doing anything with these properties because you're responsible to manually restore them in any event - not much help I can provide then.

I just used underscore.clone
to make a copy, and reassign it back after the test
Something like
beforeEach ->
sinon.stub($, 'ajax')
@obj = _.clone(obj)
obj.modifyMe = 'whatever'
afterEach ->
$.ajax.restore()
obj = @obj
delete @obj
from sinon.
_.clone would only provide a shallow copy. I have an object which has nested objects and i need to stub/mock the nested object's property. Is my only option is to do deep cloning or is there something better to achieve the same?
