mocha

问题 I have a working Node application and I'm trying to add Mocha tests, but getting some odd import errors. This is my file structure: package.json index.js src/ chart.js test/ test_chart.js This is what my chart.js file looks like: global.jQuery = require('jquery'); global.$ = global.jQuery; require('typeahead'); require('bloodhound'); var bootstrap = require('bootstrap'); var Handlebars = require('handlebars'); var Highcharts = require('highcharts-browserify'); var parse = require('csv-parse')

问题 I am trying to stub a sails controller function, but I don't know which object to stub. using sinon.stub(object,'funcname', function()... This is probably related to the way sails bind controller functions... Here is some code to give example Controller file api/controllers/PersonController.js var fs = require('fs'); // // I want to stub retrieveData function when testing // function retreiveData(cb) { fs.readFile('./filedata', function (err, data) { if (err) throw err; cb(data.toString()); }

问题 I'm using Mocha bdd for unit testing. Within my specifications, multiple test cases make use of the same assertions. I would like to pull these shared assertions out into a reusable block. How can I do this? 回答1: Here is an example of parameterized tests: 'use strict'; var assert = require('chai').assert; var pascalize = require('inflection/pascalize'); var providers = [ { name: 'Single Word', input: 'commons', output: 'Commons' }, { name: 'Single Space', input: 'creative commons', output:

问题 I have a repo that contains multiple components, most of them in JavaScript (Node.js) and one written in Ruby (Ruby on Rails). I'd like to have one .travis.yml file that triggers one build that runs all the tests for each of the components. According to this Travis CI Google Group thread, there is no official support for this for now. My directory structure looks like this: . ├── buildserver ├── core ├── extensions ├── webapp ├── Vagrantfile ├── package.json ├── .travis.yml └── Makefile I

问题 If I leave mocha watching for changes, every time I save a file mongoose throws the following error: OverwriteModelError: Cannot overwrite Client model once compiled I know that mongoose won't allow to define a model twice, but I don't know how to make it work with mocha --watch . // client.js var mongoose = require('mongoose'); var Schema = mongoose.Schema; var clientSchema = new Schema({ secret: { type: String, required: true, unique: true }, name: String, description: String, grant_types:

问题 I would like to mock out super calls, especially constructors in some ES6 classes. For example import Bar from 'bar'; class Foo extends Bar { constructor(opts) { ... super(opts); } someFunc() { super.someFunc('asdf'); } } And then in my test, I would like to do something like import Foo from '../lib/foo'; import Bar from 'bar'; describe('constructor', function() { it('should call super', function() { let opts = Symbol('opts'); let constructorStub = sinon.stub(Bar, 'constructor'); new Foo(opts

问题 I am creating XMLHttpRequest javascript module to get JSON data from server. Here is the code: (function() { var makeRequest = function(url,callback,opt) { var xhr; if (XMLHttpRequest) { // Mozilla, Safari, ... xhr = new XMLHttpRequest(); } else if (ActiveXObject) { // IE try { xhr = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { xhr = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {} } } if (!xhr) { callback.call(this, 'Giving up :( Cannot create an XMLHTTP instance', null);
