Bingo for meetings–part 2–working at tests


Bingo is a small project, written in TypeScript , and developed with Alexandru Badita in launch break (one hour - more or less). You can find sources at . Those are my blog posts for Bingo : ( scroll below for the post)

So now because we have created the objects and a function to create meetings, we do create some tests. We decided to work with JEST.


  1. We read many tutorials ( , , , , , )
  2. We solve many errors  ( forgetting put “ export default class “ , “ jest unexpected token import “ ,  jest.config.json  as opposed to jest.config.js
  3. Read jest expect documentation from
  4. We finally wrote 2 tests in order to verify meeting creation and run with npm test


import MeetingsFactory from '../MeetingsFactory';

import Meeting from '../meeting';

describe('Meetings creation', () => {

it('a meeting should have been created properly', () => {

const mf=new MeetingsFactory();

const m1=mf.CreateMeeting("andrei","first meeting");

expect(m1.Name).toBe("first meeting");




it('two meeting have different ids', () => {

const mf=new MeetingsFactory();

const m1=mf.CreateMeeting("andrei","first meeting");

const m2=mf.CreateMeeting("andrei","first meeting");





And with this we just verify first use case

Create Meeting Bingo:

As a user, I want to create a new meeting bingo: I use an username and meeting name and the application generates an unique Id that I can access the bingo cards ( state :  not checked) for that meeting


And not even the whole(  we do not have the cards , not the state for the cards!)
