Thanks but I did not solve my problem.

Here is the whole script :

require File.expand_path(File.dirname(**FILE**) + ‘/edgecase’)

# Greed is a dice game where you roll up to five dice to accumulate

# points. The following “score” function will be used to calculate the

# score of a single roll of the dice.

# A greed roll is scored as follows:

# * A set of three ones is 1000 points

# * A set of three numbers (other than ones) is worth 100 times the

# number. (e.g. three fives is 500 points).

# * A one (that is not part of a set of three) is worth 100 points.

# * A five (that is not part of a set of three) is worth 50 points.

# * Everything else is worth 0 points.

# Examples:

# score([1,1,1,5,1]) => 1150 points

# score([2,3,4,6,2]) => 0 points

# score([3,4,5,3,3]) => 350 points

# score([1,5,1,2,4]) => 250 points

# More scoring examples are given in the tests below:

# Your goal is to write the score method.

def score(dice)

total = 0

h = Hash.new(0)

dice.each {|el| h[el] += 1}

dice.each {|number, count|

if number == 1 and count == 6 then return 2000 end

if number != 1 and count == 3 then total = total + 100 * count end

if number != 1 and count == 6 then return 600 end

if number == 1 and (count > 3) then total = total + ( 100 + ( count -

3)) end

if number == 1 and (count < 3) then total = total + 100 * count end

if number == 5 and (count > 3) then total = total + ( 50 * (count

-3)) end

if number == 5 and (count < 3) then total = total + 50 * count end

}

end

class AboutScoringProject < EdgeCase::Koan

def test_score_of_an_empty_list_is_zero

assert_equal 0, score([])

end

def test_score_of_a_single_roll_of_5_is_50

assert_equal 50, score([5])

end

def test_score_of_a_single_roll_of_1_is_100

assert_equal 100, score([1])

end

def test_score_of_multiple_1s_and_5s_is_the_sum_of_individual_scores

assert_equal 300, score([1,5,5,1])

end

def test_score_of_single_2s_3s_4s_and_6s_are_zero

assert_equal 0, score([2,3,4,6])

end

def test_score_of_a_triple_1_is_1000

assert_equal 1000, score([1,1,1])

end

def test_score_of_other_triples_is_100x

assert_equal 200, score([2,2,2])

assert_equal 300, score([3,3,3])

assert_equal 400, score([4,4,4])

assert_equal 500, score([5,5,5])

assert_equal 600, score([6,6,6])

end

def test_score_of_mixed_is_sum

assert_equal 250, score([2,5,2,2,3])

assert_equal 550, score([5,5,5,5])

end

end

And I now get this error: <0> expected but was <[]>.

When I make that one a comment :

def test_score_of_an_empty_list_is_zero

```
#assert_equal 0, score([])
```

end

Then I see this error appear :

So something is not well here ?
