私は Test-First-Ruby を通じて Ruby を学んでいますが、単語を豚のラテン語に翻訳するプログラム用に書いたコードに問題があります。翻訳された単語を返す代わりに、空の文字列になってしまいます。ここに、私のコード、それをテストするための仕様ファイル、および端末で仕様ファイルを実行しようとしたときに取得する失敗/エラー コード (Mac OS 10.12、Ruby 2.5.0) を順番に示します。
コードは次のとおりです。
def translate(string)
array = string.split(" ")
pigged_array = array.map! {|x| pigify(x)}
result = pigged_array.join(" ")
return result
end
def pigify(word)
vowels = ["a", "e", "i", "o", "u"]
if vowels.include? word[0].downcase
puts word + "ay"
# two cases for "qu"
elsif word[0..1] == "qu"
puts word[2..-1] + "quay"
elsif word[1..2] == "qu"
puts word[3..-1] + word[0..2] + "ay"
# for words that start with 3 consonants
elsif !(vowels.include? word[0]) && !(vowels.include? word[1]) && !(vowels.include? word[2])
puts word[3..-1] + word[0..2] + "ay"
# for words that start with 2 consonants
elsif !(vowels.include? word[0]) && !(vowels.include? word[1]) # for 2
puts word[2..-1] + word[0..1] + "ay"
# for words that start with a single consonant
else
puts word[1..-1] + word[0] + "ay"
end
end
ここにスペックファイルがあります:
require "04_pig_latin"
describe "#translate" do
it "translates a word beginning with a vowel" do
s = translate("apple")
expect(s).to eq("appleay")
end
it "translates a word beginning with a consonant" do

end

end

end
そして最後に、端末でスペック ファイルを実行したときに表示されるメッセージは次のとおりです。
