Description

During the 2 hours Coding Dojo attendees will be assigned 4 coding challenges. Coding opportunities will be provided in C#, Java and Ruby. A version in JavaScript and Python will be provided. Attendees will face the challenge of refactoring existing code in order to make it testable and to write unit tests. After coding, we will compare the initial legacy code and the code after refactoring and with unit tests. We will higlight the changes required to make the code testable and relatied improvement in the design. This coding dojo is based on the paper and related presentation 'TDD with Mock Objects: Design Principles and Emergent Properties' [1] and the coding exercises are included in 'The Coding Dojo Handbook' by Emili Bache [2].

Prerequisites

Laptop with up'n'running development environment (C#, Java or Ruby. Or JavaScript and Python) and the framework for unit testing. Fluency in one of the 4 languages supported for the coding dojo. Previous experience in Unit Testing. Interest in unit testing and refactoring of legacy code.

Benefits for the attendees
