chai-roughly
![npm](https://img.shields.io/npm/v/chai-roughly-v2.svg)
Deep equal assertions with tolerance for chai.
Why a v2?
This is a forked version from Turbo87/chai-roughly, which have been updated
to use the latest version of chaijs/deep-eql, rather than using a modified forked
version.
Installation
npm install --save-dev chai-roughly-v2
Usage
After importing chai
, add the following code to use chai-roughly-v2
assertions:
const chai = require('chai');
chai.use(require('chai-roughly-v2'));
Now you can use the expect(...).to.roughly.deep.equal(...)
chain for deep
equals assertions with tolerance for numbers. The default tolerance is 1e-6
and can be overwritten by using e.g.
expect(...).to.roughly(0.001).deep.equal(...)
.
const { expect } = chai;
it('works', () => {
const result = { value: 41.9999999 };
expect(result).to.roughly.deep.equal({ value: 42 });
});
