Dude! Pls create a tutorial of MongoDB and Node.js but without using mocha, maybe creating a basic CRUD could help at the end of all the training. Thank you so much professor Shaun.

I specified "_id" in addition to "name" in " 'Mario', _id: char._id}, {name: 'Luigi'}).then() ", otherwise, the updating record test would fail.

[idontwhy]

the async update's response comes back with the updated record, is there a reason why we need to separately find it again? I could just write my assertion w/ that

[alvaronieto]

Why is it not using .toString for find the id?

[swagz]

how to add something to a record in mongodb?

Hi Ninjamaster! It fails when running :
db.mariochars.findOneAndUpdate({name:"Mario"}, {"name":"Luigi"});
in mongo shell, it says
"Error: the update operation document must contain atomic operators
But this one works:
db.mariochars.findOneAndUpdate({name:"Mario"}, {$set: {"name":"Luigi"}});

[gmlinns]

should use useFindAndModify: false to get ride of warning. like this mongoose.connect("mongodb://localhost/testaroo",
{
useNewUrlParser: true,
useFindAndModify: false
});

this tutorial could have been improved by not using mocha
