Dependency Injection

This repo contains code to study the notion of "dependency injection" from the ground up, without any framework.

What do we have in the code?

We have a "pseudo system", which allows us to create a fisherman. We can ask the fisherman to get some fish for us. To do that, he will need some equipment: boots, a boat, bait and of course a fishing rod. It's a wonderful world: whenever the fisherman uses his fishing rod, he will get fresh fish.

We have a unit test that validates the behavior of the system. Let's fix the problem!

Phase 1

• Fork the repo
• Open the project in the IDE
• Run the test and see it fail
• Read the code

Phase 2

• Fix the code to make the test pass
• Open a pull request

Phase 3

• Review the solutions
• Introduce the notion of dependency injection
