> It is entirely orthogonal. Of course a well-designed microservice is easier to test than a monolithic ball of mud, but a well designed monolith is also easier to test than a poorly designed spaghetti of microservices. I would also add that a well-designed monolith is inherently easier to test than a functionally equivalent well-designed microservices architecture.
