implementing-al-interfaces
Defines AL interfaces and interface patterns with implementing codeunits, creates extensible enums to switch providers, and enables dependency injection for unit testing AL code with mocks. Use when building plugin architectures, adding loose coupling, replacing conditional logic with polymorphism, or creating Business Central extensions with swappable implementations.
