It’s time to complete a full end-to-end test with the front-end application using your smartphone - this step requires the use of an iPhone or Android device.
Open the barcode scanner on your smartphone. Some phone models may require the use of a free QR scanner app instead of the default barcode scanner. Scan the QR code on the Display App. If a barcode isn’t currently shown because the screen is in a timeout period, wait until the timer counter ends and the barcode reappears.
Sign into the app using the account you created in a previous section.
Interact with the Barista app to Make or Cancel the drink and note how the Display and Customers apps are updated.
Repeat steps 2-6 to place additional orders and experiment with the application’s functionality. You can also navigate to the Step Functions console to see the workflows for each coffee drink.
Congratulations! You have completed an end-to-end backend test for the Serverlesspresso application. If you have time remaining in the workshop, complete the optional module to add a new microservice to the app that creates a Coffee Journey report for each customer.
