Ruby fork with all the fixes. Please, review and approve (the author is inactive).

Tests should use RSpec 3.0.

Tests should use assert_equal instead of expect.

The user can redefine giftwrap.

Actual/expected values are flipped in the sample tests.

You need to return an integer, not a string.

✘ Got 34 from gift #1, expected 34.
✘ Got 22 from gift #2, expected 22.
✘ Got 94 from gift #3, expected 94.
✘ Got 59 from gift #4, expected 59.
✘ Got 87 from gift #5, expected 87.
✘ Got 28 from gift #6, expected 28.
✘ Got 62 from gift #7, expected 62.
✘ Got 71 from gift #8, expected 71.
✘ Got 5 from gift #9, expected 5.
✘ Got 47 from gift #10, expected 47.

What's this about? Why is this failing?

42 is only the correct answer for the example test...

Don't understand... I returned 42 but the tests failed. Also the test gave different failures even though I was running the same code...

The test provided as a sample (see below) is useless. giftwrap method is not available to the person solving the kata.

Test.assert_equals(42, unwrap(giftwrap(42)))

Nice kata! Now I want it to be Christmas :)
