Palindrome instruction unclear about elixir HOT 3 CLOSED

It's always worthwhile improving the exercises!

The README uses the same description across all the language tracks, which means that we're intentionally vague when it comes to actual data structures, since these vary quite broadly. https://github.com/exercism/x-common/blob/master/palindrome-products.md

However, having more examples and a link to the wiki page would be great.

I'll let the others comment on the suggestion for improving the test, since I don't write elixir.

I just did this exercise and it took me awhile to figure this out as well. I came here to post an issue to discuss with anyone and this was already here. +1 to making this more clear somehow. I think the first test for this should just show the structure of the return data, for example:

  test "structure from first 2 factors" do
    palindromes = Palindromes.generate(2)
    expected = %{
      1 => [[1, 1]],
      2 => [[1, 2]],
      4 => [[2, 2]]
    }
    assert palindromes == expected
  end

we might want something more but I agree with @mayppong on the return values of this exercise were very confusing.

I've posted an issue in x-common about fixing the README. The test suite would need to be fixed here, though, so I'm leaving this issue open.
