sinon

I'm using Node.js with felixge's node-mysql client. I am not using an ORM. I'm testing with Vows and want to be able to mock my database, possibly using Sinon. Since I don't really have a DAL per se (aside from node-mysql ), I'm not really sure how to go about this. My models are mostly simple CRUD with a lot of getters. Any ideas on how to accomplish this? With sinon, you can put a mock or stub around an entire module. For example, suppose the mysql module has a function query : var mock; mock = sinon.mock(require('mysql')) mock.expects('query').with(queryString, queryParams).yields(null,

I have an ES6 module that needs jquery. import $ from 'jquery'; export class Weather { /** * Constructor for Weather class * * @param latitude * @param longitude */ constructor(latitude, longitude) { this.latitude = latitude; this.longitude = longitude; } /** * Fetches the weather using API */ getWeather() { return $.ajax({ url: 'http://localhost:8080/weather?lat=' + this.latitude + '&lon=' + this.longitude, method: "GET", }).promise(); } } Module works fine when use it in my main module but the issue is with the test that I am writing for it. Here's the test: import {Weather} from '../js

Are there any libraries out there to mock localStorage ? I've been using Sinon.JS for most of my other javascript mocking and have found it is really great. My initial testing shows that localStorage refuses to be assignable in firefox (sadface) so I'll probably need some sort of hack around this :/ My options as of now (as I see) are as follows: Create wrapping functions that all my code uses and mock those Create some sort of (might be complicated) state management (snapshot localStorage before test, in cleanup restore snapshot) for localStorage. ?????? What do you think of these approaches

I am trying to stub a method using sinon.js but I get the following error: Uncaught TypeError: Attempted to wrap undefined property sample_pressure as function I also went to this question ( Stubbing and/or mocking a class in sinon.js? ) and copied and pasted the code but I get the same error. Here is my code: Sensor = (function() { // A simple Sensor class // Constructor function Sensor(pressure) { this.pressure = pressure; } Sensor.prototype.sample_pressure = function() { return this.pressure; }; return Sensor; })(); // Doesn't work var stub_sens = sinon.stub(Sensor, "sample_pressure")

I am using Mocha, Chai, Karma, Sinon, Webpack for Unit tests. I followed this link to configure my testing environment for React-Redux Code. https://medium.com/@scbarrus/how-to-get-test-coverage-on-react-with-karma-babel-and-webpack-c9273d805063#.7kcckz73r I can successfully test my action and reducers javascript code, but when it comes to testing my components it always throw some error. import React from 'react'; import TestUtils from 'react/lib/ReactTestUtils'; //I like using the Test Utils, but you can just use the DOM API instead. import chai from 'chai'; // import sinon from 'sinon';
