測試與sanitize方法

Question

我有這個在我application_helper.rb：

def bbcode(text) 
    # Code snippets 
    text.gsub!(/\[code=?["']?(.*?)["']?\](.*?)\[\/code\]/mis) { CodeRay.scan($2.strip, $1.to_sym).div(:line_numbers => :table)} 
    text = sanitize(text, :tags => %w(span div table tr td br pre tt), :attributes => %w(id class style)) 
    # Gist embedding 
    text.gsub!(/\[gist\](.*?)\[\/gist\]/) { $1.split(" ").map { |gist| "<script src='http://gist.github.com/#{gist}.js'></script>" } } 

    # allows for nested quotes 
    bbquote(text) 

    # non-attributed quote 
    text.gsub!(/\[quote\](.*?)\[\/quote\]/mis) { "<div class='center'><div class='quote'>" << $1 << "</div></div>" } 

    # Terminal example 
    text.gsub!(/\[term\](.*?)\[\/term\]/mi) { "<span class='term'>" << $1.gsub(/^\r\n/,"").gsub("<","&lt;").gsub(">","&gt;") << "</span>" } 

    # URLs 
    text.gsub!(/\[url=["']?(.*?)["']?\](.*?)\[\/url\]/mis) { "<a rel='nofollow' href='" << $1 << "'>" << $2 << "</a>" } 

    # handle with care... 
    bbcode_ext(text) 
end 

作爲一個優秀的Rails開發者，我已經嘗試寫此方法測試：

require File.dirname(__FILE__) + '/../spec_helper' 
describe ApplicationHelper, "general" do 
    include ApplicationHelper 
    it "should correctly encapsulate double quotes" do 
    bbcode('[quote="Kitten"][quote="Dog"]QUOTE INSIDE[/quote]QUOTE OUTSIDE[/quote]').should eql("<div class='center'><div class='quote'><b>Kitten wrote:</b><div class='center'><div class='quote'><b>Dog wrote:</b></div></div>QUOTE OUTSIDE</div></div>") 
    end 
end 

當我去運行這個測試但是我得到這個錯誤undefined method 'white_list_sanitizer' for Spec::Rails::Example::HelperExampleGroup::Subclass_1:Class

這是因爲Spec::Rails::Example::HelperExampleGroup::Subclass_1:Class！= ActionView::Base。我如何測試使用清理方法的代碼？

Mixin規範假設您想要單獨測試mixin - 因此混合是混合到規範中的，您需要嘲笑它們期望存在的任何方法。所以在這種情況下，你可以嘲笑'消毒'

但是，在這裏它看起來像你真的想測試的調用消毒你的行爲結果你想要的方式，所以你不想測試你的幫手在隔離，但與視圖對象集成...

因此，創建一個擴展::的ActionView基地的規範對象，混入你的助手，然後該對象

class AView < ActionView::Base 
    include ApplicationHelper 
end 

describe AView, "general" do 

    it "should correctly encapsulate double quotes" do 
    AView.new.bbcode('[quote="Kitten"][quote="Dog"]QUOTE INSIDE[/quote]QUOTE OUTSIDE[/quote]').should eql("<div class='center'><div class='quote'><b>Kitten wrote:</b><div class='center'><div class='quote'><b>Dog wrote:</b></div></div>QUOTE OUTSIDE</div></div>") 
    end 
end
