Extend Sinon stubs for Mongoose methods to test chained methods easily
$ npm install sinon-mongooserequire('sinon');
require('sinon-mongoose');If you are using a version < 2 of
sinon-mongoosewe recommend you to use sinon-as-promised to haveresolvesandrejectsmethods on stubs.
If you want to test this
MongooseModel.find()
.limit(10)
.sort('-date')
.exec()
.then(function(result) {
console.log(result);
});Just mock and expects as usual and use chain to expects the chained methods.
Finally call resolves or rejects (remember to require sinon-as-promised).
sinon.mock(MongooseModel)
.expects('find')
.chain('limit').withArgs(10)
.chain('sort').withArgs('-date')
.chain('exec')
.resolves('SOME_VALUE');See complete example
