Using Sinon to stub chained Mongoose calls

Question

I get how to stub Mongoose models (thanks to Stubbing a Mongoose model with Sinon), but I don\'t quite understand how to stub calls like:

myModel.findOne({\"

If you use Promise, you can try sinon-as-promised:

sinon.stub(Mongoose.Model, 'findOne').returns({
  exec: sinon.stub().rejects(new Error('pants'))
  //exec: sinon.stub(). resolves(yourExepctedValue)
});
