chai-subset-in-order



"containSubsetInOrder" object properties matcher for Chai assertion library

It works in similar way as chai-subset.
However in arrays it must be the same order to pass an assertion.

Installation
===========

npm install --save-dev chai-subset-in-order

Usage
=====

``js
const chai = require('chai');
const chaiSubsetInOrder = require('chai-subset-in-order');

chai.use(chaiSubsetInOrder);
const expect = chai.expect;

expect({ foo: 2, bar: 3 }).to.containSubsetInOrder({ foo: 2 });
expect({ foo: 2, bar: 3 }).to.containSubsetInOrder({ bar: 3 });
expect({ foo: 2, bar: 3 }).to.containSubsetInOrder({ foo:2, bar: 3 });
expect({ foo: 2, bar: 3 }).to.not.containSubsetInOrder({ foo: 5 });
expect([{ foo: 123, bar: 456 }, { baz: 111 }]).to.containSubsetInOrder([{ foo: 123 }]);
expect([{ foo: 123, bar: 456 }, { baz: 111 }]).to.containSubsetInOrder([{ bar: 456 }]);
expect([{ foo: 123, bar: 456 }, { baz: 111 }]).to.containSubsetInOrder([{ foo: 123 }, { baz: 111 }]);
expect([{ foo: 123, bar: 456 }, { baz: 111 }]).to.not.containSubsetInOrder([{ baz: 111 }, { foo: 123 }]);
