1. Build out the wiki with the acceptance criteria tests

2. Create the fixture

   1. if the fixture links to the wiki you are good to go

3. Perform a draft design of the components required

4. For each component develop its code following a TDD life cycle, you would use a unit testing framework here

5. Integrate your components so that the tests on the wiki incrementally pass

Here is an wiki script for the Find Highest Number problem

!contents -R2 -g -p -f -h
 
!define TEST_SYSTEM {slim}
 
!path C:\work\find-highest-number\target\find-highest-number-1.0-SNAPSHOT.jar
 
|import                         |
|com.celestial.findhighestnumber|
 
|Find Highest Number Fixture|
|Numbers   |Expected Value? |
|4,5,90,7  |90              |

|Find Highest Number Fixture |
|Numbers List|Expected Value?|
|[4,5,90,7]  |90             |

Further challenge

Rather than just returning the highest number also sort the the array of integers

Here is the wiki script

!contents -R2 -g -p -f -h
 
!define TEST_SYSTEM {slim}
 
!path C:\work\software\netbeans\tdd-find-highest-number\target\tdd-find-highest-number-1.0.jar
 
|import                         |
|com.celestial.tdd.fitnesse.demo|
 
|Find Highest Number Fixture|
|Numbers   |Expected Value? |
|4,5,90,7  |90              |

|Find Highest Number Fixture |
|Numbers List|Expected Value?|
|4,5,90,7    |90             |

|Find Highest Number And Sort Array Fixture|
|Numbers List         |Sorted List?        |
|4,5,90,7             |4,5,7,90            |
