TL;DR

This post is about scenario testing. Scenario test is when we combine several features of the application, so we test user flow that solves user problems with our application.

Here is the so-called, happy ATM scenario:

Enter Card

Enter correct PIN

Enter Withdraw Money

Enter Amount That Is available from your current account balance

Confirm that you want paper transaction recipe

Card goes out

Money goes out

There is message Wait for recipe

Recipe is printed

ATM screen is in an initial state with the Welcome message.

As recently I got a mobile banking application, I do not need a paper recipe because I can check my account balance in real-time. So I choose that I do not want a paper transaction recipe. Here is how the scenario goes from that point:

Answer no for paper transaction recipe

Card goes out

Money goes out

There is message Wait for recipe

The recipe is NOT printed

ATM screen is in an initial state with the Welcome message.

Conclusion

This looks like a copy-paste error. Developers first created a happy scenario, and after that scenario without printing paper recipe. The message is providing false information to the customer. The customer could not be sure that his recipe with account balance won’t eventually be printed.
