Quick Guide to Performance Testing for Banking Applications
- November 21, 2014
Technology is evolving day-by-day. Every single day news and televisions are chock full of headlines with the progress in the tech industry. Similarly, the Banking sector is no more left behind like every other sector. In today’s software industry, banking applications are considered as one of the most complicated enterprise applications. The finance domain is undergoing a tremendous transformation with the advancements in technology and digitalization as a trend. To cope up with the new innovations and technologies, for the sake of better survival in the rapidly growing market and competition, financial institutes are heading towards different digital or online applications. With this switch to online banking applications, the concern for cybersecurity is more common.
In a financial application, the performance of the app matters a lot. For instance, if a user is in dire need of transferring some amount from his/her account to another, but the app isn’t logging in, then the results would be in the user frustration. That’s the point where Performance testing for banking applications comes in and is a critical exercise. Due to the fact that Banking Applications contain complex transactions, Therefore Database load testing is as important as functional testing.
LET US TAKE A QUICK LOOK AT WHAT MAKES BANKING APPLICATIONS SO CHALLENGING TO TEST AND HOW WE CAN RECOMMEND A BETTER WAY OF TESTING THEM.
Banking applications are directly related to a customer’s account that holds maximum records at a time. These applications can be used by different users for a variety of different purposes. The reliability and scalability of any Banking application are more desirable because they deal with critical monetary transactions. Most significantly, Performance testing of legacy banking applications is a challenging and complex task to perform.
ISSUES WITH LEGACY BANKING APPLICATIONS:
Most of the time the latest performance testing tools do not support the old technology being used in the bank’s legacy applications. So these applications need to be upgraded to the latest technology to get maximum support for this exercise. Legacy banking applications do not support the maximum no. of users to perform business transactions at the same time. Legacy banking applications are also less responsive and reliable to support their transactions processing less time to complete.
The latest performance testing tools based on the latest technology architecture do not entirely or partially support the legacy banking business transactions. Sometimes tools do not record the business process the first time. This would skip the important business transaction during recording. This is a very critical issue, if you miss any single step or process during business scenario recording, you might not be able to reflect the exact business load on the server and all your load testing exercise would be wasted. So in the legacy application, we have to make sure that we have covered each and every business process during recording.
For Banking Applications, we must ensure each and every business process has been covered during…
The performance test consultants have to record the business processes multiple times and need to verify the recorded script at the end so this is a time-consuming process, but for legacy applications, we have performed this task repeatedly until it records all the processes.
The latest performance testing tools with legacy banking applications failed to fulfill any of these “Roll Back” and “Commit” Actions. In bank legacy applications many transactions consist of rollback and commit actions. These commit and rollback actions make sure the status of the transactions made by different users. If all the processes are completed successfully, then the commit action confirms the transaction at the end, otherwise, it rolls back all the process and returns the fail status. These issues are very critical and all these issues should be handled carefully, otherwise without these concepts load testing would be less effective.
RECOMMENDED TOOL FOR HANDLING LEGACY APPLICATIONS:
The market is a chock-full of software testing tools to tackle the security concerns of banking applications along with the early detection of risks and vulnerabilities that can be easily exploited by the attackers. The main challenge in the load testing exercise of legacy business applications is to make the scripts work according to the real-time business scenario execution. IBM® Rational® Integration Tester is a powerful tool that supports these kinds of legacy banking applications. Rational Integration Tester supports all banking business transaction concepts, including (rollbacks, commits) actions.
IBM RIT is an effective tool that supports legacy banking applications
RIT fully supports the latest/legacy banking applications, starts from recording business scenarios to load generation and performance testing processes. Multiple agents integrated with RIT generates distributed load on application under test. These agents are flexible and can be used according to different performance testing requirements.

RIT record all the business transaction queries in a sequence executed in the actual business process. All recorded queries (Select statements, Update queries, Table Locking Statement, Insert, and Delete) are moved to “Test Factory” for performance test execution.
RIT is an efficient performance testing tool to resolve “Commit”, “Roll Back” transactions actions in legacy banking applications. RIT allows us to bring all the recorded queries together under a single SQL command. This would make a whole bunch of business process queries under Single SQL Command. During performance testing processes this technique would support “Roll Back” and “Commit” actions at the end of each transaction which determines the status of transactions (Fail or Pass).

At the end of each performance test, RIT generates a performance test summary report.

RIT generates reports and draws various performance graphs showing all the iterations and transactions along with their respective time durations for each business scenario for detailed analysis.
Have you ever been in a situation where you had to wrap your head around testing a difficult banking or financial application? Of course, you might be or you may be in the future. So to get yourself prepared with the future security threats for banking apps it is better to plan the use of an effective tool from now.
