Is there a mathematica test suite we could adapt or a standardized set
of tests we could use? Maybe we could take the 100 most often used

Randomised? No. But I have tested my code for computing theta

I couldn't find any good spline routines in Sage for constructing simple

As long as the result is either

b) An integer
then comparison should be very easy. As a dead simple example,
1) Generate a large random number n.
2) Use is_prime(n) in Sage to determine if n is prime or
