Failing spec

[ronaldtse]

  1) Glossarist::Collections::BibliographyCollection populated bibliography correctly
     Failure/Error: expect(items.size).to be 1

       expected #<Integer:3> => 1
            got #<Integer:1> => 0

       Compared using equal?, which compares object identity,
       but expected and actual are not the same object. Use
       `expect(actual).to eq(expected)` if you don't care about
       object identity in this example.
