Have you noticed how everyone has an opinion about LSP - usually the strong one - yet hardly anyone can explain it clearly? It would sound even stranger if I told you that you can automate the verification of the Liskov Substitution Principle. That is how clear it is!
Let me change that unfavorable situation by drawing you back to the fundamental principles of OOP. I will teach you how to formalize the definition of a type, either a class or an interface, to define the rules every subtype must satisfy. That will be the Liskov principle at work.
With the abstract properties defined, every implementation of an interface and every subclass will always produce objects that are substitutable for objects of their parent type - just as the LSP would define them.
