How to check whether my app following S.O.L.I.D. Principle I have created one app in kotlin, I tried to follow all OOPS and SOLID principles in my app. But after development of whole app i want to check whether any class is missing or breaking rules of SOLID principle. Try 1 Review the whole code in each class whether they are following SOLID principles of not. But if i have large number of files then it will take more time. How can we do it automatically to check whether my app is following SOLID principles.
