Using Sinon to stub a mongoose model

I am trying to stub a mongoose model to return a json value

the code that i have is

var valueToReturn = {
                      name:'xxxxx'
                     };

var stub = sinon.stub(MyModel.prototype,'findOne');

stub.returns(valueToReturn);

I get this error : TypeError:Attempted to wrap undefined property findOne as function

Take a look to sinon-mongoose. You can expects chained methods with just a few lines:

// If you are using callbacks, use yields so your callback will be called
sinon.mock(YourModel)
  .expects('findById').withArgs('abc123')
  .chain('exec')
  .yields(someError, someResult);

// If you are using Promises, use 'resolves' (using sinon-as-promised npm) 
sinon.mock(YourModel)
  .expects('findById').withArgs('abc123')
  .chain('exec')
  .resolves(someResult);

You can find working examples on the repo.

Also, a recommendation: use mock method instead of stub, that will check the method really exists on the original object.
