Integrating Cucumber and Puppeteer into your code base

Let’s add the necessary packages to our project:

1. Start by installing the packages we’re after. As well as Cucumber and Puppeteer, we’ll also pull in @babel/register, which will enable us to use ES6 features within our support files:

   $ npm install --save-dev @cucumber/cucumber puppeteer 
   $ npm install --save-dev @babel/register

2. Next, create a new file named cucumber.json with the following content. This has two settings; publishQuiet turns off a bunch of noise that would otherwise appear when you run tests, and requireModule hooks up @babel/register before tests are run:

   {
     "default": {
       "publishQuiet": true,
       "requireModule": [
         "@babel/register"
       ]
     }
   }

3. Create a new folder called features. This should live at the same level as src...
