An alternative is to use Jest. It has this functionality built-in: test.each` a | b | expected ${1} | ${1} | ${2} ${1} | ${2} | ${3} ${2} | ${1} | ${3} `(‘returns $expected when $a is added $b’, ({a, b, expected}) => { expect(a + b).toBe(expected); });
Imagine the following scenario: Write your own test suites with Mocha Use Karma to run programmatically your Mocha tests cross-browser and cross-devices More, integrate Karma with your Jasmine existing environment Even more, integrate Karma in your Continuous Integration cycle Use a million Karma plugin to check coverage, complexity, framework stuff, etc… The power of Karma … Read more
You can use this.currentTest.state (not sure when this was introduced): afterEach(function() { if (this.currentTest.state === ‘failed’) { // … } });
That error happens when, as it says, you run it with any number of nodes other than 1. Similar to jQuery, your find call will return some number of nodes (really it’s a single wrapper that knows how many nodes your find selector has found). And you can’t call simulate against 0 nodes! Or multiple. … Read more
Surprisingly, no one has suggested Buffer.equals. That seems to be the fastest and simplest approach and has been around since v0.11. So your code would become tmpBuf.equals(testBuf)
A bit late, but for people coming from search engines, here is another solution: var expect = require(‘chai’).expect expect(foo).to.be.a(‘number’) expect(foo % 1).to.equal(0) The number check is required because of things such as true % 1 === 0 or null % 1 === 0.
The reason your test isn’t running is because src/utils.js is not a valid Node.js library. According to the RequireJS documentation, in order to co-exist with Node.js and the CommonJS require standard, you need to add a bit of boilerplate to the top of your src/utils.js file so RequireJS’s define function is loaded. However, since RequireJS … Read more
Right, after some digging I’ve managed to get this working. I’ve added “nyc”: { “include”: “app”, // Only looks in the app folder “exclude”: “**/*.spec.js” } to my package.json. Since I’m using webpack I’ll probably try and find a way of defining this rule in the webpack.config.js file (if possible at all). I’ll come back … Read more
This is what I usually do within the test: var result = query_result; var members = []; result.forEach(function(e){ members.push(e.title); }); expect(members).to.have.members([‘expected_title_1′,’expected_title_2’]); If you know the order of the return array you could also do this: expect(result).to.have.deep.property(‘[0].title’, ‘expected_title_1’); expect(result).to.have.deep.property(‘[1].title’, ‘expected_title_2’);
Had the same issue and almost gave up using Mocha with TypeScript (in our case Angular 9). This is what helped me: In tsconfig.json: Replaced this: “module”: “esnext”, with this: “module”: “commonjs”, Also here I found a working example of Mocha with TypeScript and used the tsconfig file from there to compare with mine: https://medium.com/@RupaniChirag/writing-unit-tests-in-typescript-d4719b8a0a40
