저는 루비 튜토리얼을 배우려고합니다. 인쇄 가능한 메소드를 테스트하는 마지막 예제를 전달하려고합니다. 나는 루비 프로그램 내에서 메소드를 직접 호출하여 메소드를 테스트했으며, 필요한 메소드가 무엇인지 정확하게 알려준다. 내 코드가 제대로 전달되지 못하게하는 요인은 무엇입니까? 어떤 도움이라도 대단히 감사합니다.rspec 테스트가 통과하지 않습니다
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' => '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')

end
end
여기에 내가 인쇄 기능을 위해 지금까지 만든 작업은 다음과 같습니다 :
다음은 RSpec에 파일의
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
을 여기에 오류 발생 :
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 ==)
