Iso8583 simulator Setup Layout

Test Data

All test cases are stored in Excel sheets. So does card data, key data, validation data and authorization rules. Other sources are possible.

Connections

Easy UI configuration, stored in JSON format in javascript file, easy version control.

Messages

Easy to configure via UI, but also via javascript JSON editing directly, so easy to deliver, store and massively update.

Business logic

javascript is key here. We use it to user menus for transactions, build transaction data, call core features and of course, handle message contents. The user can see all its work.

Authorization logic

Configurable authorization rules and validation are available in Excel, but more logic is built into javascript authorization, like when to do cryptogram checks and PIN validation, or when to override default response codes

neaPay Core

The power of our simulator comes from its script engine, with support for connections, message building and formatting, its look and feel are the UI which makes it all easy, but its heart is the controller which manages it all.

The UI

It is responsible to make it all pleasant for you to configure connections, messages and fields.

The Engine

It is responsible for running the scripts and do the processing.

The Controller

handles the connections, provides and handles data to and from the script engine and UI, as well as files, databases or TCP/IP.

Visa Acquirer Issuer simulator

Acquiring from Visa can be easily simulated by our neaPay engine. How does it work? Load the Visa scripts in our simulator engine, the Visa message format, and do not forget the test cases. Make sure you point to the IP and port you need and start firing away those transactions like they came from Visa. Authorize in your system and our scripts will wait for the response to validate.
Visa Issuer is loaded the same way, just use authorization scripts for issuing, and select the connection type to be a server. The scripts know what messages to wait for, process and respond. It is the best way to test your system before going to certification with Visa. You do not want to keep the certification open for too long.

MasterCard Acquirer Issuer simulator

MasterCard Acquiring is just as easy. Load the BankNet scripts, as well as the messages and test cases, point the simulator to your system and run transactions. One by one, in batches or in full regression mode, it is all a matter of choice. All messages go out in parallel and can come back in any order. Just like a real authorization system.

MasterCard Issuing works with the same scripts, but uses the issuer part of them. The logic in the scripts decides that when you select the option to listen as a server.

Diners, Amex, JCB, CUP simulator

Diners, Amex, JCB, China Union Pay? For the engine it is a matter of loading a different script and formatting messages differently. For the tester it is just a difference of test cases. And IP/port.
Acquiring or issuing, that is just an option.
Pre-certification tests with any switch will give you confidence and you will have the flexibility to test beyond the certification test cases.
If you are a switch , you can use our simulator to certify member banks with your switch!

POS, ATM and e-commerce simulator

POS and e-commerce transactions work just as easily. Load the scripts, the transactions and start testing. Or make changes to match your custom interfaces, and then test as much as you want.

Each ATM vendor comes with a different format and it may be a little more complicated. To be honest, if your vendor provides a simulator for the ATM, use that one. If you need something heavily customized, then neaPay's engine will definitely be able to do it. Contact us and tell us what device you have, we might have the scripts for it already. If not, it is never too late to write a new one.

Regression Testing

A new code release comes and you need to make sure your system did not lose any functionality. You want to check that limits are working just as fine as before, that the accounts are debited and usages are updated. Each of them. A good regression pack can detect whether your limits are working fine, your balances are fine, all your fields are formatted correctly, for each transaction type, and your transactions are approved or declined as before. With that peace of mind, you can proceed to test the enhancements. Our simulators are designed with a regression approach from the beginning, therefore, any new functionality can be easily added to the regression pack, so next time you apply changes, these enhancements will be tested as part of the regression. After a few years, you will have a nice regression pack of a few hundred or thousand transactions, which can be run in less than an hour to check the status of the system, any day or night. You want this, we know you do, and our simulator can do it very well.

Automatic Regression Testing

We know that you need the functionality above and you know you want it executed as soon as possible. What is your estimate for running a complete regression for the system, that covers everything, with 1000 test cases? You may say a week, you may say maybe two, or you may dare to estimate 2 days. We say that takes an hour. Because that is the estimate we wanted in our test plans and we made the simulator that can do that. Once all is set up properly, click the Run and go for a coffee. When you come back, you have your answer.

Performance Testing

Your system must do all the processing at very high speed, so we built a matching simulator, which can run just as fast. We believe that 60 transactions need to be run in 3 seconds, not 30. We hope you agree. So our simulator can run fast enough to be used for performance testing, even without caching features. We have in plan to add a caching feature, which can release hundreds of transactions per second, it will be here soon!

Step by step guide to enable and disable fingerprint reading, enrollment and verification.

Enabling traces in the payments simulator

Enabling traces in the ISO8583 Payments Simulator, just like the ISO8583 message converter and the ISO8583 Host, is a call to the system core to write additional data. This will, most of the times, show raw data (binary data is dumped as hex) for better understanding what is going on, what data is actually being used.

Most importantly, enabling traces shows dumps of TCP traffic or actual data being written to files, queries do database and so on. This is to verify that you are sending the correct data.

Altering test cases in Excel for the ISO8583 simulator

When you need to customize your own test case, you need to follow some simple steps all the time.
