public class FibonacciTest
extends TestCase

FibonacciTest is a glassbox test of the Fibonacci class. Recall that the Fibonacci sequence is a recursive sequence where the first two terms of the sequence are 1 and all subsequent terms are the sum of the previous two terms. Thus, the Fibonacci sequence starts out as 1, 1, 2, 3, 5, 8, 13... The first 1 in the sequence is considered the "0th" term, so the indices that ps0.Fibonacci uses are 0-based.
