Bingo for meetings–part 2–working at tests

Bingo

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 https://github.com/alexandru360/PresentationBingoCards/ . 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.

Steps:

1. We read many tutorials (https://medium.com/@mtiller/debugging-with-typescript-jest-ts-jest-and-visual-studio-code-ef9ca8644132 , https://rjzaworski.com/2016/12/testing-typescript-with-jest , https://github.com/facebook/jest/tree/master/examples/typescript , https://amenallah.com/node-js-typescript-jest-starter/ , https://basarat.gitbooks.io/typescript/docs/testing/jest.html , https://dev.to/muhajirdev/unit-testing-with-typescript-and-jest-2gln )
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 https://jestjs.io/docs/en/expect.html#not
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");

expect(m1.Participants.length).toBe(1);

expect(m1.Participants[0].Name).toBe("andrei");

})

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

const mf=new MeetingsFactory();

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

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

expect(m1.Id).not.toBe(m2.Id);

})

})

 

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!)
