If you would like some test cases that I wrote for my mpz_t 
wrapper, you should look in 
https://github.com/andrew-m-h/libgmp/blob/master/source/deimos/gmp/operators.d and take the bottom two unittests.
The test cases are more complex than just your usual a + b:
- a verification of Fermat's Little Theorem for mersenne primes 
M(p) p < 200
- a 'rediscovery' of Lander & Parkin's counter example to Euler's 
Sum of Powers Conjecture.
  i.e. finding: 27^5 + 84^5 + 110^5 + 133^5 = 144^5

They should be trivially translateable to your interface, and 
test out your library for speed ;)

I was planning on extending this wrapper but since you have one, 
you may as well have the test cases.
