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.

I tracked it down to two main things: Focus Feedback I’ll come back to that later. I’m also a big fan of Test Driven Development. Guess what,  I performed a root cause analysis on TDD, too. And once again: Focus Feedback After that, I asked myself: “Are there other things I like with these root causes?”. Yes there are: Playing Volleyball and...

I’m often hearing thoughts about Test Driven Development from people not using it, which are not true (at least not 100%).
Therefore, I want to describe some of these myths here:

Writing unit tests is difficult and complex
Projects take longer because of the additional test code that has to be written
Not everything can be tested with unit tests. Therefore TDD cannot be used.
There is no need for architecture and design because TDD claims to evolve that from tests
