Running tests

There are two sets of tests:

1. Browser tests run with Cypress
2. Node tests run with Karma and Mocha

To run both the browser and Node tests:

• npm run dev to start local server.
• npm run test then run tests in a separate process

To run just the browser tests with the Cypress UI:

• npm run dev to start local server
• npm run test:browser or
• npm run cypress to view the Cypress UI

To run just the Node tests:

• npm run test:node

Adding tests
