Ok. I’ve tried to read other questions here but still didn’t find a straightforward answer.
How can I assert a partial object match in an array using chai? Something like the following:
var expect = require('chai').expect; var data = [ { name: 'test', value: 'bananas' } ]; expect(data).to.be.an('array').that.contains.somethig.like({name: 'test'});
Just to clarify, my intention is to get as close to the example provided as possible.
- to chain after the
.be.an('array')
and - to provide only the partial object as a parameter (unlike chai-subset).
I really thought that expect(data).to.be.an('array').that.deep.contains({name: 'test'});
would work, but it fails on not being a partial match and I’m kinda screwed there.

Since chai-like@0.2.14
the following approch will work:
var chai = require('chai'), expect = chai.expect; chai.use(require('chai-like')); chai.use(require('chai-things')); // Don't swap these two expect(data).to.be.an('array').that.contains.something.like({name: 'test'});
