Same here. on this and others. It's very frustrating.

done. this kata have some tests with 0

Needs to have test case that is a valid solution, in that there are no repeats, except that one number is not in range(1,10). For Example

test.assert_equals(done_or_not([
                     [0, 3, 4, 6, 7, 8, 9, 1, 2], 
                     [6, 7, 2, 1, 9, 5, 3, 4, 8],
                     [1, 9, 8, 3, 4, 2, 5, 6, 7],
                     [8, 5, 9, 7, 6, 1, 4, 2, 3],
                     [4, 2, 6, 8, 5, 3, 7, 9, 1],
                     [7, 1, 3, 9, 2, 4, 8, 5, 6],
                     [9, 6, 1, 5, 3, 7, 2, 8, 4],
                     [2, 8, 7, 4, 1, 9, 6, 3, 5],
                     [3, 4, 5, 2, 8, 6, 1, 7, 9]]), 'Try again!');
