我正在尝试围绕我刚刚编写的 Ruby Rails 应用程序设置 RSpec 测试。该应用程序是一个更大项目的附加组件，我对环境还不是很熟悉。我以前也从未使用过 RSpec，所以这很可能是一个基本问题。
首先，我编写了一些不应该失败的基本测试：
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
但是，当我运行这些测试时，我得到了这个错误：
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 如何影响 RSpec 测试？到目前为止，我的任何工作都没有涉及 Redis。我进行了一些搜索，但找不到任何其他提及此错误的内容。
谢谢你的帮助！
