Since we are using yarn v2 here we need to setup some things:

1. Some of the jest-puppeteer dependecies are not declared
   So we explicitly install and connect with .yarnrc.yml.

2. We need to add babel-jest and related dependencies
   So we can write tests with future Ecmascript features.

Rename tests and description;
Create constants for easy of modification;
Start writing helpers for testing;
Setup jest to run in band with -i flag

Should investigate doing this with expect.extend({});
Would make the API closer to standard Jest behavior;
