Llewellyn Falco - Hands-on workshop for Better Unit Testing

Hands-on workshop for Better Unit Testing or Learning about Learning

by Llewellyn Falco

Bring your laptop to try out a koan (puzzles for learning). A Koan is a set of failing unit tests. Learning by doing with koan puzzles is fun, engaging, and produces remarkably quick results. Koans can be used to learn a variety of programming skills including languages and APIs. This session will challenge you in group and individual settings to complete these puzzles to get the unit tests to pass. After you decode the puzzle, we will reflect on what and how you have learned. Finally we will look into how to create your own koans for your particular testing needs.

This is a unique session will explore the use of the open source library Approval Tests to facilitate better unit testing verification in a collaborative fun workshop.

    Great seeing everyone! By the way, someone left a gray fleece/sweater during the event. Anyone feel a little chilly leaving the building?

    Very insightful teaching to have us understand our thought processes and how our mind works. Let's do some more of this!

    Not sure if I can make it tonight. What language will the unit tests be in? My current laptop only has Linux on it, so I can't bring in a laptop with Windows...yet.
