私はrubyの学習チュートリアルに取り組んでおり、印刷可能なメソッドをテストする最後の例に合格しようとしています。Ruby プログラム内でメソッドを直接呼び出してメソッドをテストしたところ、必要なものが正確に出力されました。私のコードが正しく通過するのを妨げているのは何ですか? どんな助けでも大歓迎です。
rspec ファイルは次のとおりです。
require 'dictionary'
describe Dictionary do
before do
@d = Dictionary.new
end
it 'is empty when created' do
@d.entries.should == {}
end
it 'can add whole entries with keyword and definition' do
@d.add('fish' => 'aquatic animal')
@d.entries.should == {'fish' => 'aquatic animal'}
@d.keywords.should == ['fish']
end
it 'add keywords (without definition)' do
@d.add('fish')
@d.entries.should == {'fish' => nil}
@d.keywords.should == ['fish']
end
it 'can check whether a given keyword exists' do
@d.include?('fish').should be_false
end
it "doesn't cheat when checking whether a given keyword exists" do
@d.include?('fish').should be_false # if the method is empty, this test passes with nil returned
@d.add('fish')
@d.include?('fish').should be_true # confirms that it actually checks
@d.include?('bird').should be_false # confirms not always returning true after add
end
it "doesn't include a prefix that wasn't added as a word in and of itself" do
@d.add('fish')
@d.include?('fi').should be_false
end
it "doesn't find a word in empty dictionary" do
@d.find('fi').should be_empty # {}
end
it 'finds nothing if the prefix matches nothing' do
@d.add('fiend')
@d.add('great')
@d.find('nothing').should be_empty
end
it "finds an entry" do
@d.add('fish' => 'aquatic animal')
@d.find('fish').should == {'fish' => 'aquatic animal'}
end
it 'finds multiple matches from a prefix and returns the entire entry (keyword + definition)' do
@d.add('fish' => 'aquatic animal')
@d.add('fiend' => 'wicked person')
@d.add('great' => 'remarkable')
@d.find('fi').should == {'fish' => 'aquatic animal', 'fiend' => 'wicked person'}
end
it 'lists keywords alphabetically' do
@d.add('zebra' => 'African land animal with stripes')
@d.add('fish' => 'aquatic animal')
@d.add('apple' => 'fruit')
@d.keywords.should == %w(apple fish zebra)
end
it 'can produce printable output like so: [keyword] "definition"' do
@d.add('zebra' => 'African land animal with stripes')
@d.add('fish' => 'aquatic animal')
@d.add('apple' => 'fruit')
@d.printable.should == %Q{[apple] "fruit"\n[fish] "aquatic animal"\n[zebra] "African land animal with stripes"}
end
end
これまでのところ、印刷可能な機能のために作成したものは次のとおりです。
class Dictionary
def initialize(opts = {})
@opts = opts
end
def entries
@opts
end
def add(opts)
opts.is_a?(String) ? @opts.merge!(opts => nil) : @opts.merge!(opts)
end
def keywords
@opts.keys.sort
end
def include?(key)
@opts.has_key?(key)
end
def find(key)
@opts.select { |word,defin| word.scan(key).join == key }
end
def printable
opts_sorted = @opts.sort_by { |word,defin| word}
opts_sorted.each do |word,defin|
print "[#{word}] \"#{defin}\"\n"
end
end
end
エラーは次のとおりです。
1) Dictionary can produce printable output like so: [keyword] "definition"
Failure/Error: @d.printable.should == %Q{[apple] "fruit"\n[fish] "aquatic animal
"\n[zebra] "African land animal with stripes"}
expected: "[apple] \"fruit\"\n[fish] \"aquatic animal\"\n[zebra] \"African lan
d animal with stripes\""
got: [["apple", "fruit"], ["fish", "aquatic animal"], ["zebra", "African
land animal with stripes"]] (using ==)
