During the last couple of years, the financial organizations (and not only) have been captured by microservices architecture trend. Thus, we have been looking for a solution to easily, quickly and conveniently cover microservices business logic with autotests. So, we sat down on grass, thought a while and ... decided to create it ourselves. We did not yet know what problems we were about to face with, but how could we feel fine watching shadows on the wall? Let us introduce you how the BSC AuTe-Framework for the backend was built almost from scratch, why did we burn our fingers (more than once sometimes), how the framework was acquiring functionality and what do we have now. Also, a separate part will be devoted to our experience of moving to open-source (https://github.com/BSC-RUS/AuTe-Framework), what stages were passed before and how to live with it now. And, last but not least, this solution is relevant not only for BSC projects, it could be suitable for you as well!
