Mastering Liskov Substitution Principle in Apex
Summary
The article explains how to apply the Liskov Substitution Principle (LSP) in Apex to create more reliable and maintainable Salesforce code. It focuses on using LSP to build safer interfaces, enable dependable dependency injection, and develop trustworthy mocks for testing. Following these principles helps Salesforce developers avoid common pitfalls and deliver more robust, scalable code architectures. Teams can improve interface design and testing reliability by adopting LSP in their Apex code.
