Experience Agile Programming Agile Meetup, Sri Lanka Johannes Brodwall Steria Featuring: Shihan Iqbal

Goal Introduce Agile To have fun now! For you to have fun now! For you to have fun later (stretch goal)

Agenda What is «agile programming» What to look for Demonstration Discussion Possibly: Tips and tricks

What is «agile programming»?

What is Agile?

Deliver frequently

=> Incomplete code

Incomplete code => Ability to change

Ability to change => Quality and discipline

Practicing discipline: Ping pong

Ingredience #1: Pair programming

Ingredience #2: Test driven development

Failing test Write code Failing test Write code Failing test

Ingredience #3: Refactoring

Failing test Write code Failing test Write code Failing test Refactor code and tests

Put together

Failing test Write code Failing test Write code Failing test

Write code Failing test Write code Failing test Refactor code and tests

What effect do you expect? On time On cost On quality On work environment

Demonstration

What to watch for?

If you’re a project manager

If you’re a developer

If you’re a tester

If you’re neither

Please: Talk about what you see to the person next to you (whisper) Tweet

Demonstration (Featuring Shihan Iqbal)

Kata: Minesweeper

What did you see?

How often did we switch ”driver”? Effects of pairing? What did the ”non-driver” do? How do you expect it to be different?

What do you think? Pairing two seniors? Pairing two juniors? Pairing senior and talent? Pairing senior and junior?

What did you see? Was the step size right? What was the first test? How did we decide next test? What was the final test?

What did you see? Did we refactor the right amount? How long was the code red? Strengths in final design Weaknesses in final design Enough comments?

How to practice

Practice Practice at work Practice katas Practice in dojos

Why become better at programming?

Seriously. Why?

Only 13.37% of effort

Getting better quality

Correctness Maintainability

But more importantly!

Think better

Raise your level of abstraction
