chai-callslike
A simple assertion to validate many aspects of stub calls. It is supposed to use with sinon + chai.
How it works
expect(stub).callsLike
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:
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.
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:
expect(myStub).callsLike();If you expect the stub to have been called with no parameters, pass empty arrays:
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:
expect(myStub).callsLike(
[sinon.match.object, sinon.match.string, sinon.match(/.+foo.+goo/)]
);The generated log will look pretty as this:
