chai-samsam

chai-samsam

Extends Chai with an assertion for deeply matching just about any kind of object using samsam.
This project started out as a fork of chai-deep-match.
Its interface and test cases have been retained and all pass. Thus it can be used as a drop in replacement.
However, it allows for much looser and deeper matching. (See the samsam docs)

Install

$ npm install --save chai
$ npm install --save chai-samsam

Usage

const chai = require('chai')
const chaiSamSam = require('chai-samsam')

chai.use(chaiSamSam)

expect([{
  firstName: 'John',
  lastName: 'Doe',
  jobs: [{ bartender: true, barista: true }]
}]).to.deep.match([
  { jobs: [{ barista: true }] }
])
// =>  pass

expect([{
  firstName: 'John',
  lastName: 'Doe',
  jobs: [{ bartender: true, barista: true }]
}]).to.not.deep.match([
  { jobs: [{ pilot: true }] }
])
// =>  pass

// also possible
assert.deepMatch(a, b)
assert.notDeepMatch(a, b)
