I'm unable to achieve should.fail,

const BigNumber = web3.BigNumber;
require('chai')
  //.use(require('chai-as-promised'))
  .use(require('chai-bignumber')(BigNumber))
  .should();

it("should fail", function() {
  should.fail(0, 1, "Didn't failed");
});

got this error "TypeError: should.all is not a function"

sorry this is the correct one "Error: Invalid Chai property: fail. Did you mean "all"?:

any advice

Keith Cirkel

@keithamus

should.fail is not a valid test I think

you might have meant should.throw but that test looks more like you want 0.should.not.equal(1)

Hello , I register the chai module in my wdio.conf.js file

require('chai/register-assert');

In my test file I write:

assert.equal(...);
assert.include(...);

For assert.equal I get a Warning in my IDE: require() call is missing

hi, I'm looking for advice on testing API endpoints with chai-http

I want to do some negative testing, checking that certain endpoints return 404 or 401 etc.

but they cause the request to throw an error

what's the best way to handle that?

UncleGus

@UncleGus

ending up using .then and .catch and just flipping the resolve/reject

Hi there

im trying to use chai for my expect conditions, but thet functions done seem to be available even though i have installed the dependencies

im using appium webdriverio for my tests

any leads on how i can get chai setup successfully?

Lars Gyrup Brink Nielsen

@LayZeeDK

@ajmalmajeed I use this (TypeScript):

import * as chai from 'chai';

const expect: Chai.ExpectStatic = chai.expect;

expect(someCondition).to.be.true;

Ajmal Abdul Majeed

@ajmalmajeed

alright, thanks @LayZeeDK

Hi @SchnuWu_twitter , normally this happens because of the linting. For example, eslint allows for a global field in .eslintrc config file where you can define the global variables you have. You can also add there "describe" and "it".

Hi guys,

anyone knows how long does it take for Chai to detect a new plugin in npm and add it to the official list in https://www.chaijs.com/plugins/ ?

how can I use chai http to send http request? I got a curl command curl -H "Content-Type: application/json" -X POST -d '{"voiceFilePath":"https://api.voicerss.org/?key=8593c9ec738c4059963f15c139d9f41f&src=%22basf%22&hl=en-us&c=wav"}' http://10.12.10.36:9090/load/ and I expect this output: {"status":"SUCCESS","message":"Loaded","voiceFilePath":"6030039c-5626-47f9-8fde-ccb17c3d9b17.wav","recordingDuration":0,"audioData":null}

my code snippet: function callAPIHelper(endpoint, input) {
const chai = require('chai');

const serverUrl = xlVAServer[0].ServerURL;
const payload = {
voiceFilePath: input
}

chai.request(serverUrl)
.post(endpoint)
.set('Content-Type', 'application/json')
.send(payload)
.expect(200)
.expect((res) => {
expect(res, body.text).toBe(payload)
});

but I got this error:chai.request is not a function

Hi all, i'm trying to test a node.js class that extends EventEmitter but the test returns ok even before the event is fired. Why this happen? Maybe there is a proper way to test data emitted by events.
Here is the test code, basically it have to validate a json emitted on the tick event.

const chai = require('chai')
chai.use(require('chai-json-schema'))

const { expect } = chai

const RideSimulator = require('../src/RideSimulator')

describe('RideSimulator run()', () => {
    it('should return a json compliant to the schema', () => {

        let schema = { ... schema omitted ... }

        let ride = new RideSimulator(1, 1)

        ride.on('tick', (busData) => {
            expect(busData).to.be.jsonSchema(schema)
        })
    })
})

Hello! I’m trying to use chainable getter AND. Not sure if this syntax is correct: expect(someCondition).to.be.true.and.expect(otherCondition).to.be.false
If not what would be the correct one using AND
Thanks in advance!!

Kwirke

@kwirke

Hi @walternolak ,

When you concatenate assertions with .and, you are still referring to the same test subject, so you can't chain another expect. Instead, do a new line and have two separate assertions beginning with expect()

Bonus points if you make it as two different tests (it block) because that's a recommended good practice for clarity: One assertion per test

walternolak

@walternolak

@kwirke Understood! thanks for your response.

@hollowsunsets

hello, I'm trying to test some asynchronous functions to see if they throw errors when expected

i've read that you no longer need chai-as-promised to do this

do you know what exactly I'd need to change? this is what I have right now and i'm not sure if it's correct syntactically

await expect(object.classMethod()).to.eventually.be.rejectedWith(TypeError, "errorMessage");

Dan Čermák

@dcermak

Is there a simple way how I can make a plugin "return a value" from an assertion chain?

for example, let's say I have this chain ctx.should.do.foo(barFuncThatReturnsSmth) and I'd like this chain to return the return value of barFuncThatReturnsSmth

I have tried to override this._obj in the definition of the method foo, but that didn't work. The object is there, but is not returned directly (it's hidden inside some __flags object)

Anyone interested in an opensource project?

Spec oriented development speeds up programming by generating code based on tests/specs. Tests required will be the same or less specs as a normal developer writes.

@sven14_gitlab

is it possible to pass true or false as argument, e.g.

    expect(
      selector.isEnabled(),
      "msg",
    ).to.be.(Enabled)

where Enabled is true or false?

Eric Eastwood

@MadLittleMods

@sven14_gitlab Yes, you can use expect(selector.isEnabled()).to.be.(true)
