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({\"         


        

Answer 1

I use promises with Mongoose and stub the methods like this:

const stub = sinon.stub(YourModel, 'findById').returns({
    populate: sinon.stub().resolves(document)
})

Then I can call it like:

const document = await YourModel.findById.populate('whatever');
