You can pass a custom message as a second argument to assert:
assert(condition, "message goes here");
I think there are testing libraries/frameworks around that mean to provide
more than the basic built-in things. But I haven't tried any, so I can't
recommend anything. Try searching for "test" here: http://code.dlang.org/
