Whether VBA can do serious OOP isn’t a question – it absolutely can: none of the SOLID principles have implications that disqualify VBA as a language, and this means we can implement dependency injection and inversion of control.This article will go over the general principles, and then subsequent articles will dive into various dependency injection techniques you can use in VBA code.

They are great source of knowledge and motivation to be It achieves that by decoupling the usage of an object from its creation. This helps you to follow SOLID’s dependency inversion and single responsibility principles. I am currently working on the Authentication system. In this article, we explore both types of DI and how you can use it to write testable code. Each layer's implementation does not even need to include the header files for other layers. It is based on the Open/Closed Principle and the Liskov Substitution Principle. You should, therefore, at least be familiar with these two principles, before you read this article. In this one, I will focus on the Dependency Inversion Principle. Dependency Inversion Principle Example Let's take an example of a simple Customer Management example. Languages that support higher language functions can often solve simple dependency inversion problems by passing behaviour as a function instead of an object which implements an interface in the OO-sense. Dependency injection is a programming technique that makes a class independent of its dependencies. We're going to look at DI next. Dependency Inversion in OOP means that you code against an interface which is then provided by an implementation in an object. Congratulations on studying S.O.L.I.D.These are some of my favorite principles.
