Testing

Mocha - https://mochajs.org/

const assert = require('assert');

describe('Array', function() {
	describe('#indexOf()', function() {
		it('should return -1 when the value is not present', function(){
		  assert.equal(-1, [1,2,3].indexOf(4));
		});
	});
});

Enzyle testing

Official documentation - https://airbnxb.io/enzyme/docs/api/ReactWrapper/find.html General walk through and setup - https://scotch.io/tutorials/testing-react-components-with-enzyme-and-jest

it('Rank default values are passed on and rendered', () => {
    const wrapper = mount(<GameUI/>);
    expect(wrapper.find('.currentPoints').text()).toEqual('Points: 0');
    expect(wrapper.find('.currentRank').text()).toEqual('Rank: 1');
    expect(wrapper.find('.curretRankPoints').text()).toEqual('Rankpoints: 7');
  });

Express - The little server that could:

const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => res.send('Hello World!'))

app.listen(port, () => console.log(`Example app listening on port ${port}!`))

Bundler cheat codes

bundle install #install all gems

bundle update #update all gems to latest possible version. This ignores gemfile.lock, very possibly that it causes issues.

bundle init #non-rails way to init a gemFile

gem install bundler -v "~>1.0"  #If you NEED a version of bundler that is older use this...

Fun Facts

skeuomorphic - where an object in software mimics its real world counterpart. The “trash can” is, perhaps, the most recognizable skeuomorphic object.

Gauntlet of the damned

  • What is the difference between local and session storage?
Local Storage
Local storage is used for storing data locally on a user’s browser, like saving user preferences or other settings. It is persisted through page reloads and stays with the browser until it is cleared manually or through a setting.

Session Storage
Session storage acts in a similar way to local storage. The only difference here is that while data stored in local storage has an expiration date, the data stored in session storage will expire as soon as the page’s session ends, that’s it, when the page is closed.

  • What is the most complicated application you've worked on?
  • What's a project you've worked on that you are particularly proud of?
  • What are you looking for in your next role?
