Dependency Injection

Pros

• Classes are more modular, as they depend only on the interface of passed-in dependencies. Class behavior can be changed by swapping out a new component.
• Testing is simplified, since stubs can be substituted for any dependency.

Cons

• It's harder to understand how a class works when reading just that class. You may have to track down its invocation to see what kind of components are passed in.
