The sequence of operations is an important financial subject that has attracted the researchers' attention for many years. The quality of electronic trading platforms can be improved by validating the sequence of operations via two modes. The first one is detection and prevention of abusive behavior in the market. Surveillance systems ensure the monitoring of this parameter. The second one is verification of technical stability. Defect management is an essential part of improving software reliability by means of test tools. We propose that using data analysis and artificial intelligence can help significantly improve the quality of electronic trading.

This article highlights some of the essential common challenges of FPGA-based solutions in terms of testing and elaborates on how Exactpro approaches testing them from the standpoint of functional and non-functional testing, and verifies the correctness of their work at the confluence of functional and nonfunctional testing.

First and foremost, it is worth reviewing a typical clearing system infrastructure: there is a number of internal components, where each one is responsible for a variety of tasks, or possibly incorporates several tasks at a time. There is a significant amount of connections to the third-party systems, or in-house external systems, such as markets, market data providers, CSD, payment systems, and, of course, there is connectivity with clearing members. Having a lot of experience dealing testing such systems, the Exactpro team is used to encountering challenges on a daily basis. This paper focuses on the ones that are most prominent, and on the way Exactpro addresses them.

Shsha is a passive testing tool allowing observing the system without interacting with it.

QA, as we see it, is a continuous learning process. It is about learning how the system should operate in production, followed by learning the actual behavior of the system by way of performing tests and, after comparison, ensuring that all the discrepancies are either fixed or documented. It is the epitome of all QA activities. The other essential task that QA performs is developing the Test Design, coming up with Test Tools and Automated Test Libraries, which is an ongoing process, as opposed to learning at the beginning and testing as the end result. We are still learning when the system goes into production and still receive feedback from it. That allows us to reveal as many issues as possible.
