How to provide chai expect with custom error message for mocha unit test?

由 不问归期 提交于 2020-06-27 06:59:11
问题 I have a mocha test using chai's expect: it("should parse sails out of cache file", async () => { const sailExtractor = new Extractor(); const result = await sailExtractor.extract("test.xml"); try { expect(result.length).to.be.greaterThan(0); const withMandatoryFlight = result.filter((cruises) => { return cruises.hasMandatoryFlight === true; }); expect(withMandatoryFlight.length).to.be.greaterThan(0); const cruiseOnly = result.filter((cruises) => { return cruises.hasMandatoryFlight === false;

Chai unittesting - expect(42).to.be.an('integer')

问题 According to http://chaijs.com/api/bdd/#a, a / an can be used to check for the type of a variable. .a(type) @param{ String } type @param{ String } message _optional_ The a and an assertions are aliases that can be used either as language chains or to assert a value's type. However, I'm not able to check for the variable beeing an integer. The given examples, e.g. expect('1337').to.be.a('string'); work for me, but the following does not: expect(42).to.be.an('integer'); expect(42).to.be.an(

Mocha not exiting after test

由 落爺英雄遲暮 提交于 2020-06-24 05:36:27
问题 I'm starting with tests in Node. Using mocha, chai and nock (to intercept external HTTP api calls). I have written 3 tests, all of them are a pass, however, when I added the 3rd test, mocha stopped exiting after running the tests, with no error or indication of anything wrong. If I comment the 3rd test, mocha exits just fine. This is the test causing the 'issue': describe('tokenizer.processFile(req, \'tokenize\')', () => { it('should tokenize a file', async () => { req = { file: {

Using await / async with mocha, chai

问题 I'm quite new to node and express. And have been trying to write test code using mocha, chai and chai-http. Here's the part of source code. const mongoose = require('mongoose'), User = require('../../models/user'); const mongoUrl = 'mongodb://xxxxxxxxxxx'; describe('/test', function() { before('connect', function() { return mongoose.createConnection(mongoUrl); }); beforeEach(async function(done) { try { await User.remove({}); // <-- This doesn't work chai.request('http://localhost:3000')

how to do an “or” in chai should

由 泪湿孤枕 提交于 2020-06-13 16:50:18
问题 How do I do an or test with chai.should? e.g. something like total.should.equal(4).or.equal(5) or total.should.equal.any(4,5) What's the right syntax? I couldn't find anything in the documentation 回答1: Viewing the Chai expect / should documentation, there are several ways to do this test. Note that you can chain using "and" but apparently not "or" - wish they had this functionality. Check whether an object passes a truth test: .satisfy(method) @param{ Function }matcher @param{ String }message
