chai-callslike

!build
!test
!lint

A simple assertion to validate many aspects of stub calls. It is supposed to use with sinon + chai.

How it works

$3

Will validate the exactly interaction with the mocked method, which is:

- How many times has been called;
- Which parameters have been passed to it;
- In what order the calls happened.

How to use?

It is pretty simple to setup the chai-callslike in your tests:

``javascript
import chai from 'chai'
import {callsLike} from 'chai-callslike'

chai.use(callsLike)
`

Just pass the stub in the first parameter and, in the others, arrays with the set of parameters each calls had received.

`javascript
expect(myStub).callsLike(
['param1call1', 'param2call1', 'param3call1'],
['param1call2', 'param2call2', 'param3call2'],
);
`

If you want to check if the stub had never been called, pass just the stub:

`javascript
expect(myStub).callsLike();
`

If you expect the stub to have been called with no parameters, pass empty arrays:

`javascript
expect(myStub).callsLike([], [], [])
`

_(in this example, myStub have been called three times with no parameters)_

You can also use sinon matchers to validate the parameters instead of exact values:

`javascript
expect(myStub).callsLike(
[sinon.match.object, sinon.match.string, sinon.match(/.+foo.+goo/)]
);
``

The generated log will look pretty as this:
