To run these tests, run:

npm test

To run locally, do:

npm run test-local

There's a training mode that can be enabled. Currently this is done by changing 'training' to true in specs/utils/compare.js and running the following command:

node specs/utils/reference-server.js

This generates and collects reference PDFs from real browsers. This should be done before refactoring a plugin or component to ensure output is exactly identical.

This will in future also allow us to create reference images to compare against visually.
