Sample Recommended design for an Acquirer test cases suite, Scenarios and Regression

Posted on 4th Oct 2018 2133 views

A test suit is composed of different scenarios which follow in a functional (or another) way in order to cover the full, or as much as possible, of the ISO8583 Interface implementation.

You should go through your Functional specification document and assess all functionality that you want to use.

Design test cases for all the functionality that you want to use, like below. Also, design test cases for the functionality you do not want to use, to make sure you are blocking it. For example, if you are not going to accept magnetic stripe transactions, make sure to have a scenario that checks that magnetic stripes transaction are failing. This is not very straight forward, because you need to distinguish between transactions that just have track2 data together with other fields, and transactions that have only track2 data. Also, you may want to allow fallback, for example if the ATM is damaged. Many options are avaialbe and a lot of work. We can offer support, consulting advice or even implementation of a complete regression pack.

Let us focus on testing valid scenarios and let us consider a generic interface. What test cases should be present in each scenario.
