If you are running an earlier version of node, you can update with the following commands:

sudo npm cache clean -f
sudo npm install n
(or 'sudo npm install -g n' should you wish to update node globally)
sudo n stable

Or, using NVM:

nvm install node --reinstall-packages-from=node

Set the url to test against

In the test.js file, update the following variable to reflect your chosen url

const url = '<Your URL goes here>';

Install all dependencies

npm install

Run the tests

npm test

This suite provides a basic overview of the Lighthouse audit. In the event of test failures, additional information can be found by running a comprehensive Lighthouse audit
