Writing better code (and better tests) with interfaces

Interfaces are not new in AL, but after a few years of being around, they are still heavily underused both by Microsoft and by the community. And yet, they are possibly the best single addition to AL stack in the recent years, with potential to transform your coding style to other dimension.

This workshop will go deep into interfaces and show you how to make the best out of them, with a lot of practical examples, ranging from simple to advanced. You’ll get hands on about how to scale your code, make it more extensible and robust. Since interfaces have their special place in testability, you’ll learn how to use interfaces to make your code more testable, and how to take advantage of interfaces in your test code as well.
