Level: Introductory to Intermediate
Dependency Injection is one of those terms advanced programmers throw out with an expectation and assumption of full understanding. People often ask for a recommendation for a good DI product and want to learn how to use it. When discussing the subject, it becomes immediately apparent many don't even know what they're asking about. It's easy to get infatuated by a cool buzz phrase, especially when you hear so many others using it. But to truly understand something you need to start by understanding the problem spaces that it is trying to solve. To write testable software, you need to understand and embrace abstractions and injecting them. But then you introduce the problem of having to resolve dependency chains. This is where using a DI container helps you solve both these issues. During this session, you'll learn how to make your code testable and maintainable with the help of a DI container.
You will learn:
- How to demonstrate problem code
- About abstractions for across-the-board testability
- Using a full-featured DI container
