To install dependencies
npm install
To run tests
npm test
If you would like the tests to run in watch mode, run npm run test:watch.
By default this runs the tests for any files that have changed, however you can choose to only run a particular file by pressing p and then entering a pattern to match a file. For example, to only run the tests for the checkout task, you could press p then enter checkout.
To cancel watch mode, press q to quit.
