作成したばかりの Ruby Rails アプリケーションに RSpec テストをセットアップしようとしています。このアプリケーションは、はるかに大規模なプロジェクトへのアドオンであり、私はまだ環境にあまり慣れていません。また、RSpec を使用したことがないため、これは基本的な問題である可能性があります。
まず、失敗してはならないいくつかの基本的なテストを作成しました。
require 'spec_helper'
require '../../../lib/release_notes/release_notes_generator'
describe ReleaseNotesGenerator do
before :each do
@rng = ReleaseNotesGenerator.new()
end
it 'should print hello world' do
puts "Hello world!"
end
describe "#new" do
it "tests basic rspec syntax" do
@rng.should be_an_instance_of ReleaseNotesGenerator
end
end
end
ただし、これらのテストを実行すると、次のエラーが発生します。
An error occurred in an after(:all) hook.
Redis::CannotConnectError: Error connecting to Redis on 127.0.0.1:6379 (ECONNREFUSED)
occurred at /Users/nadams/.rvm/gems/ruby-2.0.0-p0@orbit/gems/redis-3.0.4/lib/redis/client.rb:276:in `rescue in establish_connection'
Redis は RSpec テストにどのように影響しますか? これまでの私の仕事には、Redis がまったく関係していません。いくつか検索しましたが、このエラーに関する他の言及は見つかりません。
ご協力いただきありがとうございます！
