Dependency Injection

Pros:

• Easy unit tests
• Decoupling - Dependencies can be configured, wrapped, changed, mocked, all without changing the parent
• Coding towards an interface - We can depend on only the things we need, no more and no less
• Ability to write code using the dependency you wish you had. Make that thing later.

Cons:

• Indirection
• Too much decoupling. Sometimes, things should stay together.
