Last year we started the program 12 months, 12 katas (as inspired by this repository). This year we want to propose something different: an asynchronous code jam
##New problem: Mini-Power Swapper
This post belongs to a series: code-jam
Each month (or so) we at GMaur will publish a new problem (and announce it on twitter) and post a solution to the last problem.
This month, the Mini-Power Swapper

I’ve written a RPN string calculator in java, using TDD with these: mockito, hamcrest, junit
It’s close to the String Calculator kata, by Roy Osherove. This RPN is using mocks (so more difficult than the String calculator)
I’ve tried to practice “Your tests are dragging you down” by J.B Rainsberger (mainly, to use something to write on). This behavior is also explained in the book Dirigido por tests (Spanish) by Carlos Blé.
Specifically the chapter no. 20 (“Listening to the tests”) from Growing Object-Oriented Software Guided by Tests available here is so good to learn to hear to your tests.
To hear what they’re trying to tell you, the authors (Steve Freeman and Nat Pryce) explain this to you:
I Need to Mock an Object I Can’t Replace Logging Is a Feature Mocking Concrete Classes Don’t Mock Values Bloated Constructor Confused Object Too Many Dependencies Too Many Expectations To close, a quote:
I just did the prime factors kata, in java using TDD. Results: https://github.com/alvarogarcia7/primeFactors
Code review, comments, pull requests are more than welcome

I’ve just seen this talk: Is TDD dead? Of course not! But what´s all the fuzz about then? by Emily Bache
###My notes
deliberate vs accidental learning (around minute 19)
do not be an evangelist for tdd but rather “come learn tdd, come at a dojo with us!”
points to Dan North’s talk (at the same foo café)
points to her book - The Coding Dojo Handbook
This category is mainly dedicated to anything related or included in the book ‘Growing Object-Oriented Software Guided by Tests’, by Nat Pryce and Steve Freeman
