TDD by Beck – Chapter 14 on GitHub

The code for Chapter 14 of TDD by Beck is now on GitHub

 

CH14: Change

Significant techniques are introduced here...though I had issues with Java 6 indicating that some methods (assertEquals(Object{}, Object[]) is deprecated.

* Added a Bank parameter
* Saw that the number 2 was duplicated in code and tests - so refactored it out from it as part of the rate
* A test for the ArrayEquals showed an assumption that did not work - so drove the direction of the solution....which was a separate class as a comparator (Pari)
* Wrote that (without tests!!!) as it was part of a refactorying.
* When there was an error - it forced a new test testIdentityRate() - which isolated the problem.
