Kata: Dead & Lost are friends, make them separeted, then you'll solve it.!

Ruby tests overhauled

hopefully fixed there

For input "gap", expected is ["Gap", "gAp", "gaP"], but it also includes "gap"

Where do you see "gap" there? Which language are you talking about?

Wave output should not include the original word. For input "gap", expected is ["Gap", "gAp", "gaP"], but it also includes "gap" which is not a wave. Please check test case.
for this code have all test issue

done

it's unclear whether strings consisting entirely of spaces are possible input or not. the description does say that the string can be empty, and several languages have a fixed test with an empty string that results in an empty array, which is probably the intended answer for a string consisting entirely of spaces as well.

Merged

proposed fix there

I revamped the tests. The tests' structure is now as follows:

[Test]
public void FixedTests() { /* ... */ }

[Test]
[Repeat(100)]
public void RandomTests()
{
    Solution instance = new Solution(), Codewarrior instance = new SnakeLadders();
    for (int i = 0; i < 50; i++)
    {
        // roll 2 dice
        string exp = solution.play(dice);
        string act = codewarrior.play(dice);
        Assert.That(act) IsEqualTo(exp);
    }
}

That's exactly what is being done, omitting the return keyword is just a common shorthand for 1 liner arrow functions

Nice kata, but it would be great to have a preloaded "events" dictionary that maps snakes and ladders where keys represent the old positions and values the new ones.

This would save time and effort and help prevent mistakes from transfering the values by hand.

Couldn't it be better to show why the tests aren't passing?

like saying the moves played so far so that I track where the problem in code is

my code passed 1000 tests and didn't pass another 1000 ones

I liked this kata too much because it makes You to think hard in every marshroot case. Thank You very much!
