sinon-as-promised

sinon-as-promised

Sugar methods for using sinon.js stubs with promises.

Getting Started

var sinon           = require('sinon');
var Promise         = require('bluebird');
var sinonAsPromised = require('sinon-as-promised')(Promise);

You can use any promise library you'd like that exposes a constructor. You'll only need to call sinon-as-promised once. It attaches the appropriate stubbing functions which will then be available anywhere else you require sinon. You'll probably want to call it in a setup file that is required before your tests.

Usage

stub.resolves(value)

When called, the stub will return a promise which resolves with the provided value.

stub.resolves('foo')().then(function (value) {
    // value === 'foo'
});

stub.rejects(error)

When called, the stub will return a promise which rejects with the provided error. If error is a string, it will be set as the error message.

stub.rejects(new Error('foo'))().catch(function (error) {
    // error.message === 'foo'
});
stub.rejects('foo')().catch(function (error) {
    // error.message === 'foo'
});
