chai

In javascript (ES6), I have a utility module which just contains some functions, and then in the end of the file, I export them like so: module.exports = { someFunction1, someFunction2, someFunction3, } Then I want to write unit tests for those functions. Some of the functions depend on each other; they call each other in a way, that for example, someFunction1 might call someFunction2. There's no circular problems. Everything works well, until I need to spy that one of the functions is called. How can I do it? Currently I'm using Chai and Sinon. In the test file, I have imported the whole file

So I have this code, createExampleDir is not yet implemented, so the test fails: let chai = require('chai'); let expect = chai.expect; let homeDir = require('home-dir'); let lib = require('../lib.js'); chai.use(require('chai-fs')); let dir = homeDir('/example-dir'); describe('lib', () => describe('createExampleDir', () => it('should find ~/example-dir', () => lib.createExampleDir() .then(() => expect(dir).to.be.a.directory()) .catch(() => {throw Error('Who cares!');}) ) ) ); The problem is that I'm getting an UnhandledPromiseRejectionWarning error, the error "Who cares!" is throw, so the catch

I have seen many examples where someone takes a JavaScript function and evaluates it by doing something like: JSContext *context = [[JSContext alloc] initWithVirtualMachine:[[JSVirtualMachine alloc] init]]; [context evaluateScript:@"var add = function(a, b) {return a + b;}"]; NSLog(@"%@", [context[@"add"] callWithArguments:@[@20, @30]]); //Output is 50 But how can we run test cases on the function? By calling arguments we can see the result (assuming it doesn't throw an exception). In the event it does throw an exception we can set an exception handler on the context prior to calling the code.

I'm trying to set up a simple unit test for my hubot code and I am not receiving responses back. I have simplified this down to: test.coffee: Helper = require('hubot-test-helper') chai = require 'chai' expect = chai.expect helper = new Helper('../hubot-scripts/something.coffee') describe 'PING', -> beforeEach -> @room = helper.createRoom() afterEach -> @room.destroy it 'should PONG', -> @room.user.say 'alice', '@hubot PING' expect(@room.messages).to.eql [ ['alice', '@hubot PING'], ['hubot', 'PONG'] ] and something.coffee: module.exports = (robot) -> robot.response /PING$/i, (msg) -> msg.send

I'm learning to unit test using the node module mockery with sinon. Using only mockery and a plain class I'm able to inject a mock successfully. However I would like to inject a sinon stub instead of a plain class but I'm having a lot of troubles with this. The class I am trying to mock: function LdapAuth(options) {} // The function that I want to mock. LdapAuth.prototype.authenticate = function (username, password, callback) {} And here is the code I'm currently using in my beforeEach() function: beforeEach(function() { ldapAuthMock = sinon.stub(LdapAuth.prototype, "authenticate", function

Executing below unit test gives "Error: [$injector:unpr] Unknown provider: $stateProvider <- $state". I have attached the angular-ui-router.min.js in karma file. describe("Unit tests", function() { var $rootScope, $injector, $state; console.log("hello"); beforeEach(inject(function(_$rootScope_, _$state_, _$injector_, $templateCache) { console.log("hello1"); $rootScope = _$rootScope_; $injector = _$injector_; $state = _$state_; })); describe("states", function() { it("verify state configuration", function() { var config = $state.get("DRaaS"); console.log(config, "cc"); }); }); }); You haven't

I am trying to write a chai test where all I do is just stream some audio and get a simple response back: {} , for some reason I'm getting this error Uncaught SyntaxError: Unexpected token { when ever I pipe my fs stream to req , if I remove the piping and I don't have that stream the test works fine. server code: router.post('/', function (clientRequest, clientResponse) { clientRequest.on('end', function () {//when done streaming audio console.log('im at the end>>>>>'); clientResponse.setHeader('Content-Type', 'application/json'); //I've tried removing that: same result clientResponse.json({}

I'm new to unit testing, and I'm aware my tests may not be valuable or following a specific best practice, but I'm focused on getting this working, which will allow me to test my frontend code using JSDOM. const { JSDOM } = require('jsdom'); const { describe, it, beforeEach } = require('mocha'); const { expect } = require('chai'); let checkboxes; const options = { contentType: 'text/html', }; describe('component.js', () => { beforeEach(() => { JSDOM.fromFile('/Users/johnsoct/Dropbox/Development/andybeverlyschool/dist/individual.html', options).then((dom) => { checkboxes = dom.window.document
