红宝石存根一个Dir.glob与Rspec

我想用rspec测试我的类Episode，它会在构造函数中采用一个字符串来确定插曲编号，搜索带有相应插曲编号的插曲字幕文件并设置字幕名称的情节。红宝石存根一个Dir.glob与Rspec

我面临的问题是，我不想用真实文件测试既不创建假文件（已经做到了，它工作正常）。

我相信我需要将呼叫存根到Dir.glob，但到目前为止我一直不走运。

任何想法？

class Episode 
    attr_reader :avi_file, :subtitle_name, :number, :name, :directory 

    # an episode is instantiated with an avi filename 
    def initialize(avi) 
    @name = File.basename(avi, ".avi") 
    @directory = File.dirname(avi) 
    # Looking for an episode number in the form of 
    # s01e01 or 01x01 
    match_data = @name.match /(s\d{2,}e\d{2,}|\d{2,}x\d{2,})/i 
    @number = match_data.to_s 
    find_subtitle_in 
    puts self.subtitle_name 
    end 



    private 

    def find_subtitle_in 
    srt_files = Dir.glob("#{@directory}/*.srt") 
    @subtitle_name = srt_files.find { |e| /#{@number}/i =~ e } 
    end 

end

功能

it "does find a subtitle" do 
    episode = Episode.new "Friends s01e01.avi" 
    Dir.stub!(:glob){["Friends.s02e01 subtitle french.srt", "Friends.s01e01 subtitle french.srt" ]} 
    episode.subtitle_name.should == "Friends.s01e01 subtitle french.srt" 
    end

的

输出rspec的

1）集并找到字幕故障/错误：episode.subtitle_name.should = = “Friends.s01e01 subtitle french.srt” expected：“Friends.s01e01 subtitle french.srt” got：nil（using ==）＃./spec/lib/episode_spec.rb:25:in`block（2 levels ）在“

试试这个：

it "does find a subtitle" do 
    Dir.stub!(:glob){["Friends.s02e01 subtitle french.srt", "Friends.s01e01 subtitle french.srt" ]} 
    episode = Episode.new "Friends s01e01.avi" 
    episode.subtitle_name.should == "Friends.s01e01 subtitle french.srt" 
end
