ruby-on-rails - Pluralsight RSpec 正确的方式 : Wrong Number of Arguments for expect(client. url).to eq

Question

我刚刚开始使用 Pluralsights 的 RSpec the Right Way 模块。在尝试定义 @url = url 时，我注意到它没有像教程视频中那样着色，并且在尝试让它通过时收到以下失败。我是一个完整的 rspec 新手，所以我需要帮助来分析这里出了什么问题。

谢谢

 module Wordpress

        attr_reader :url

        def initialize url
            @url = url

  it "stores a URL" do
    client = Wordpress::Comments::Client.new 'http://mashable.com/comments/feed'
    expect(client.url).to eq 'http://mashable.com/comments/feed'
  end

end

我在 rspec 2.8.0 上遇到了同样的问题。并且较新的版本修复了它。正如它所说， Rspec 2.8.0, expect(something) causes ArgumentError: wrong number of arguments (1 for 0)
