Ascert have extensive experience in building and implementing test solutions within the Electronic Funds Transfer (EFT) marketplace using their highly flexible testing engine, VersaTest™.

Interchanges VTALK Driver Library scripts exist for most common EFT Interchanges, including: • VISANET (ISO 8583) • EUROPAY (ISO8583) • Mastercard (ISO8583) • American Express (ISO8583) • Diners Club (ISO8593) • LINK LIS5 (ISO8583) - UK • Interpay (ISO8583) - Netherlands • SAMA (ISO8583) - Middle East • BASE24 BIC (ISO8583) • BASE24 HISO (ISO8583) • IFX

VersaTest™ is a fully scripted test engine and its VTALK language allows scripts to be developed to simulate any structured message format from both a "client" (initiating message flows) and a "server" (responding to message flows) point of view.

VersaTest is used in all phases of testing from single shot prototype and development testing, through system testing and integration testing to stress testing and volume testing of complete enterprise systems. Once a system is live, VersaTest can be used to automate the regression testing required whenever an application's code, system software or hardware environment is modified.

The VPRO test engine manages the method of communication with the application under test, either over real communications lines (TCP/IP, X.25, SNA or "legacy" comms such as BISYNC and ASYNC) or via other delivery methods such as Websphere MQ series, or within the HP NonStop environment, using methods such as and PATHSEND. Within ACI's BASE24 environments, VersaTest can also be run as an XPNET satellite process, enabling the simulation of external networks and interfaces while under the control of BASE24 itself.

Devices VTALK Driver Library scripts exist for most common EFT devices, including: • NCR NDC+ ATM • Wincor Nixdorf NDC+ ATM • Diebold 910 ATM • Diebold 911 ATM • Diebold 912 ATM • NDC+ emulation ATMs • IFX ATM • APACS 30 POS • APACS 40 POS • SPDH POS • HP NonStop 6530 terminal • IBM 3270 terminal

As well as the market leading BASE24 from ACI, other EFT switches that have been tested using VersaTest include Postilion from Mosaic Software and OpeN/2 from S2 Systems.

VTALK Driver Library scripts exist for most common EFT standards, as shown on this page. Where appropriate these scripts will support the latest EMV encryption standards, with the ARQC and ARPC generated programmatically. Various other encryption and security standards are also included, for example 3DES and MAC generation. Where necessary, VersaTest can also use hardware encryption devices such as those supplied by Thales, RACAL or Attalla.

While scripts for many standard message formats already exist within the VTALK Library, where bespoke message standards are in place in an application, the VTALK language allows these to be simulated with complete flexibility.

In the past these have included other financial message formats such as SWIFT and CHAPS messages, but VersaTest has also met such widely diverse requirements as Air Traffic Control systems, Telecommunications switches and Medical systems in the past. Ascert can proudly boast that as yet we have not found a message standard that cannot be simulated in some manner using VersaTest.
