To continue my series on Mocking Katas (see Mocking Kata – Instrument Processor for the last Kata), I’ll show you a very simple Kata that I normally use in my Test Driven Development training courses to introduce mocks (created manually or dynamically with the use of a mocking framework): the CharacterCopier.
We use Coding Katas in Coding Dojos to improve our programming skills. This includes skills in software design, refactoring, Test Driven Development, Mocking, tool usage and a lot of other tiny stuff. However, I found only a few Katas, especially Katas including the need for mocks (see for example ). Most Katas are very algorithmic, which is good for learning TDD. But its bad for learning how to use mocks. Therefore, I started to invent my own Mocking Katas. I use these in my training courses...
