6. Do you know
what it is TDD?

7. Sorry -
unfortunately
most of you are
missing the point!

8. • As an interviewer
• I want that the candidate to write
a code that will replace the two
variables (INT)
• So I can figure out whether he is
the right person for the job

9. First test

10. First fail

11. Build a simple implementation

12. Add a new test

13. Fail again

14. Fix the code

15. Refactoring after NFR

16. It’s all about
A short
feedback loop

17. FizzBuzz code KATA
• Write a program that prints the
numbers from 1 to 100. But for
multiples of three print "Fizz" instead
of the number and for the multiples
of five print "Buzz". For numbers
which are multiples of both three
and five print "FizzBuzz"

25. Here are the new requirements
• A number is fizz if it is divisible by 3
or if it has a 3 in it
• A number is buzz if it is divisible by 5
or if it has a 5 in it

26. DoD should update

27. TDD as a way of working
• TDD is not a UNIT TEST
• TDD is part of the Software craftsmanship
• TDD must be adjusted to US/DoD and not to
Implementation
• If someone can understand your test
You are on the right way
• If the BA can understand your test
You are in a perfect way

28. Agile, Architecture and Architect

30. Facts About Software
Software is
low cost
Requirements

31. Agile Architecture

32. Agile Architecture - Less is More
“Just good
enough”
Parsimony -
Simplest
solution ,
Minimize
complexity
Don't be afraid
to throw
things away

33. Agile Architecture - Use Diagram
•Word >100 page
•PPTX > 60 slides

34. Agile Architecture - Use Diagram

35. TDD – Test Driven Design
Design High Level system
Build the contracts
"Fake it 'til you make it“ – make it clear
The system must be green
Now we can implement it
