Don’t hesitate to request a quote, if you need help with testing your application: our 400+ engineers have worked for 300+ projects.Modified: February 10, 2023| Excel | 5 Minutes Reading If we got you interested, continue by reading our article on “Banking Application Testing: Benefits & Use Cases”. To sum up, let me repeat: financial application testing is a must, and although it may sound complicated, in fact it is absolutely doable. The system starts degrading, and another bottleneck can appear in a while. Increasing load utilizes a lot of hardware resources, for example, RAM. Often, resources are not released, or leaked. You will need to increase the number of parallel streams so that the server would be able to process information faster, and then the level of productivity will rise, too. To increase productivity, requests are processed simultaneously instead of consequently. Highly loaded applications use several streams. The number of threads might be not enough either. Sometimes the problem is not enough connections from your back-end server to the database server, or there may be problems with particular sql requests to a database server. Let me give you an example: money transfers always work well, but cashback crushes under load. You will have to take a closer look at such places and reprofile them.Īnother issue is which operations spit out errors under high loads. This would highlight problematic locations in your code. For example, with lots of concurrent users, authorization may be quick, while money transfers may take time, or vice versa. You might want to use transaction testing to ensure the complete integrity and success of business transactions taking place via online mode. Firstly, you need to locate the slowest transactions. Other issues are specific to testing financial applications. But in some cases, acquiring additional resources doesn’t help either. The most expensive way is to buy more hardware. Unfortunately, increasing server computational power is not a universal solution, although it is relatively easily affordable. If it is in fact them limiting system productivity, you need to locate the resource where it happens. There are many important questions to look for answers for: you need to know how much RAM you have, how many servers there are, how many harddisks there are, and how fast they are. The primary reason for productivity limitations is servers’ computational power. If these 20% include requests from your mobile financial application, consider running performance testing asap. These often constitute 20% of the overall number of operations, but 80% of the load. To run performance tests, we usually use the most highly-intensive operations. To figure out if the number of users is large, just ask yourselves if mobile client operations are in the top list of your requests. If a large number of users is working with your heavy loaded system via mobile client, performance testing becomes a must. The speed of the application itself on the front end is a separate issue. However, I’d like to focus on the back end of the financial system and its performance testing. That is why it is so important to test the system under load, both on the front end and on the back end. But in recent years the popularity of mobile applications has been climbing, and they are definitely going to take the first place eventually. Providers of financial services usually suggest that their customers should use both the web version and mobile application simultaneously.
