Code Quality defines that the code is good, which means code is of high quality, and code is bad, which means code is of low quality. The quality can be subjective, so different teams may use different definitions based on the context. Code can be considered good quality if it is clear, simple, well tested, bug-free, refactored, documented, and performant.

I think any test which asserts some output based on the same action for your target class is useful as it validates the behavior of your service when it is called. Your target class or some other class under the covers may generate logs or any kind of output on the console which you want to capture to assert it.

But with it, it also requires a lot of investments from you – in terms of time and resources. Hence, you need to decide if that is really the power you need because, in the end, you need automation that gives you returns on your investment(ROI).
