Using TDD develop a CUT that finds the highest number from an array of integers

Specification

If the input were {4, 5, -8, 3, 11, -21, 6} the result should be 11
An empty array should throw an exception
A single item array should return the single item
If several numbers are equal and highest, only one should be returned
If the input were {7, 13} then the result should be 13
If the input were {13, 4} then the result should be 13
