How can violating LSP cause issues in software design?

Violating LSP can lead to:

• Unexpected behavior when a subclass does not honor the contract of the base

class.

• Code that breaks at runtime when substituting a derived class.
• Tightly coupled code that depends on specific implementations rather than

abstractions.

• Unit tests failing when testing subclasses in place of base classes.

Essentially, it defeats the purpose of polymorphism.
