What to Test

• "Happy path" (aka "Happy Day" or "Golden Path") test
  • Tests that execute customer flow without error
• For our app:
  • Create order
  • Accept terms and submit
  • Click “new order” on confirmation page
• Don’t need to test different combinations of orders
  • Covered in order page testing

New Mock Service Worker Handler

• New Handler
  • mimic POST for order confirmation with Mock Service Worker
  • implementation: call POST via useEffect in OrderConfirmation
  • make up format of the data sent to server, or send no data
  • server simply generates random order number and sends it back as JSON
• Warning about using copy/paste to create new handler
  • I do this all the time
  • If you do, be sure to change the method from get to post
  • If you neglect to do this, it's very difficult to track down!
    • Will get error like Error: connect ECONNREFUSED 127.0.0.1

Good luck!
