You also want to ensure that the API is clean, small and easy to use. Bloated API increases cognitive load on the users (developers).

If you find that something is hard to test, it means that the API is not good enough (or you’re trying to unit test something that shouldn’t be exposed)，更多细节参见51吃瓜
In MIM each module could be unit tested separately. In the circular-layers architectures… it’s hard to tell, because there are many community interpretations of what you put into the “core”. With the literal implementations everything is mixed in the “core” or “application” (and you don’t get the clear testing boundaries per process/domain). But in one of the popular community interpretations, i.e. “layers per domain”, you can get good separation, but at the cost of duplicated layers you don’t need.
