I’m doing a little hobby project to test out the ESP8266 chip and Espruino and decided to use TDD to get the hang of it. In one of the tests, I needed to check if all values of an array where equal to a value. Before starting to implement some loop logic, why not Google a bit!

Came across this chai plug-in named chai-things that does exactly what I wanted and much more.

To start using it I just needed to do:

var chai = require("chai");
chai.use(require('chai-things'));

and then use it on an array like:

status.should.all.equal(false);

Just a small note, I first tried using it like this:

status.should.all.be.false;

but it didn’t work.

There are a lot more things you can do with it, so if you are using chai, check out the docs and give it a try!
