Yes, there are already several open issues about the tests, so I'll close this one.

Sory for my bad English,
But I think that this Kata must have more tests, for example, I write a simple code where I counting amaunts in every 3*3 square,
in every horizontal and vertical line and compare this sums with 45(it is a sum from 1 to 9).
[
[4, 3, 4, 6, 7, 8, 9, 1, 3],
[6, 7, 2, 1, 9, 5, 3, 4, 8],
[2, 9, 8, 3, 4, 2, 5, 6, 6],
[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]
] - this is the test where my solution does not work, but with my silution I passed all the tests.
There you can see my code - https://pastebin.com/PDuUXBYs
I hope that not only me find this problem, sorry if I copy someones issue

and each of the nine 3x3 sub-grids (also known as blocks) contain all of the digits from 1 to 9.

{1, 2, 3,                                     4, 5, 6,                    7, 8, 9}
{2, 3, 1,  <----- pretty obvious              5, 6, 4,                    8, 9, 7}
{3, 1, 2,                    ----------->     6, 4, 5,                    9, 7, 8}
                              and here
                                                                            ^
{4, 5, 6, 7, 8, 9, 1, 2, 3}                                                 |  here, too.
{5, 6, 4, 8, 9, 7, 2, 3, 1}
{6, 4, 5, 9, 7, 8, 3, 1, 2}
{7, 8, 9, 1, 2, 3, 4, 5, 6}
{8, 9, 7, 2, 3, 1, 5, 6, 4}
{9, 7, 8, 3, 1, 2, 6, 4, 5}

Not an issue.

Test:
{1, 2, 3, 4, 5, 6, 7, 8, 9}
{2, 3, 1, 5, 6, 4, 8, 9, 7}
{3, 1, 2, 6, 4, 5, 9, 7, 8}
{4, 5, 6, 7, 8, 9, 1, 2, 3}
{5, 6, 4, 8, 9, 7, 2, 3, 1}
{6, 4, 5, 9, 7, 8, 3, 1, 2}
{7, 8, 9, 1, 2, 3, 4, 5, 6}
{8, 9, 7, 2, 3, 1, 5, 6, 4}
{9, 7, 8, 3, 1, 2, 6, 4, 5}
Expected: False
But... It's returns true;
