I’ve noticed that there is always a challenge of understanding what services are in a context of Domain-Driven Development and what is the difference between a service in an application, domain, and infrastructure layer. Domain-driven design made a lot of cleanup in the IT environment and conquered the hearts of programmers. Eric Evans is one of the most famous people who promote this not so a new way of developing software.

When you have a very simple application it’s not so important to test every edge case but in a project, in the very complex domain, the priority of it will increase. The more high-quality the tests, the more high-quality the code. Mutational tests will help you with making sure you did not miss some a variant of the flow in your code. How it works Mutational testing is a test which runs other test several times but with a bit changed production code in every iteration.
