Additions to the chai-spies library

Adds:

  • Ability to easily inspect the parameters a spy has been called with
  • Ability to check if a spy was called with a partial object

Install

npm install --save-dev chai-spies-augment

Then in your test setup file where you are loading chai spies

import chaiSpies from 'chai-spies';
import chaiSpiesAugment from 'chai-spies-augment';
...
chai.use(chaiSpies);
chai.use(chaiSpiesAugment);

Usage

Accessing spy call parameters

const spy = chai.spy();
 
spy(1, 2, 3);
spy('a', 'b', 'c');
 
const args = spy.args(); // ['a', 'b', 'c']
const argsFor = spy.argsFor(0); // [1, 2, 3] 

Checking for partial object

const spy = chai.spy();
 
spy({ a: 'b', c: 'd' });
spy(1, 'a', { b: 'c' });
 
expect(spy).to.have.been.called.with.objectContaining({ a: 'b' }); // true
expect(spy).to.have.been.called.with.objectContaining({ b: 'c' }); // true
