DisclaimerThis talk will not tell you which framework to use.

It is about deciding whether to (re)-use existing code.

What is a Framework?

IoC ContainerInversion of Control Container

A design in which custom-written portions of a computer program receive the

flow of control from a generic, reusable library

[...]

With inversion of control, it is the reusable code that calls into the custom, or

problem-specific, code.

A foolish man who built his house on the sand. And the rain fell, and the floods

came, and the winds blew and beat against that house, and it fell, and great

was the fall of it.

Matthew 7:25

In software engineering, coupling or dependency is the degree to which each

program module relies on each one of the other modules.

All dependencies are yoursChoose wisely!

SOLID?

SOLID• Single Responsibility Principle• Open/Closed Principle• Liskov Substitution Principle• Interface Segregation Principle• Dependency Inversion Principle

SOLIDD - Dependency Inversion

The principle inverts the way some people may think about object-oriented

design, dictating that both high- and low-level objects must depend on the

same abstraction.

Testing

TestingFind the smallest possible scope to test each feature.

Most important question to ask:

Does it solve my problem?

Does it solve my problem?What is my problem in the first place?
