Лог от изпълнението

........F.F.

Failures:

  1) Collection adds the artist tags to the songs
     Failure/Error: songs(tags: 'polyphone').map(&:name).should =~ ['Toccata e Fuga', 'Goldberg Variations']
       expected collection contained:  ["Goldberg Variations", "Toccata e Fuga"]
       actual collection contained:    []
       the missing elements were:      ["Goldberg Variations", "Toccata e Fuga"]

  2) Collection allows all criteria
     Failure/Error: ).map(&:artist).should eq ['Thelonious Monk']
