Ruby Koans: about_hashes.rb

[Ilya B.]

Question about this method in Ruby Koans -> about_hashes.rb

def test_changing_hashes
hash = { ne => "uno", :two => "dos" }
hash[ne] = "eins"

expected = { ne => "eins", :two => "dos" }
assert_equal true, expected == hash

# Bonus Question: Why was "expected" broken out into a variable
# rather than used as a literal?
end

Referring to the bonus question, is there any reason other than that
it's more readable this way? Seems to accomplish the same thing?

That sounds about right. Readability.

If that were true, shouldn't it be:
assert_equal expected , hash

I think it is probably a mistake, and they meant to try and show that you
can't do either of these, because it looks like you are passing a block.
assert_equal { ne => "eins", :two => "dos" } , hash
assert { ne => "eins", :two => "dos" } == hash
