Hello,
are here developers in the group who actively test (the routines they
use) e.g. by throwing random input at them?
I sometimes do random tests when testing a ticket. Better yet, such
random tests can also be added as a doctest if they don't take too long.
You can at least test that the function does not crash, but ideally you
would test the output also. For example, I once added a doctest to
determinant() for matrices over ZZ that checks that the determinant of
A^2 is a square. Besides random testing, also testing for special cases
is useful. If you have function dealing with polynomials for example,
check that the zero polynomial and constant polynomials work. Test
corner cases (e.g. smallest and/or largest allowed input). Also test
invalid input, checking that the proper exception gets raised.
