Within the framework of the project, the innovative methodology “Quality Gates Next” was applied to create continuous quality assurance of software for RBS of legal entities.

The provided software passes through several quality gateways, on which the quality of each version of the product is assessed in an automated mode, and a decision is made on the possibility of moving to the next, more resource-intensive and detailed gateway.

The project has implemented several gateways, in which each software version goes through several stages of automated testing, as well as stress testing. After passing all the developed quality gateways, the provided software is ready for acceptance by business customers.

At all stages, test environments are monitored, which is used to improve test results. The resulting system is easily scalable and allows adding new quality gateways both before and after those already implemented.
