dependency injection

I’m still working on learning Rust. Beyond syntax, learning a language requires familiarizing oneself with its idioms and ecosystem. I’m at a point where I want to explore testing in Rust. The initial problem We have used Dependency Injection a lot - for ages on the JVM. Even if you’re not using a framework, Dependency Injection helps decouple components. Here’s a basic example: class Car(private val engine: Engine) { fun start() { engine.

After years of near-ubiquitous usage of Dependency Injection, I see more and more posts and talks questioning its value. Some even go to the point where they argue against it. Most of it however is based on a whole lot of misconceptions, half-truths and blatant lies. In this post, I’d like to go back to the roots of DI, describe some related features and lists available frameworks.

It seems pretty popular right now to bash widespread software design practices, e.g. dependency injection, frameworks, annotations, etc. While there are some downsides of adopting those practices, I believe there are more benefits. In that post, I’d like to address those points, and come up with arguments in favor.

The more I program, the easier it gets. However, the more questions arise regarding programming. This week, my thinking was about Object-Oriented Programming. I’ve been told that OOP is about encapsulating state and behavior is a single isolated unit. In languages I know, state translates into attributes and behavior into methods. public class Cat { private Color color; public void mew() { ...
