example how to use 'stub' and 'mock' in sepc

Use sometime to learn stub and mock.

I think below is a good example:

 

code:

    def create_from_content(content)
      page_content = PageContent.new(content)
      templet = page_content.templet
      templet_id = page_content.templet_id
      page_title = page_content.page_title
      #OPTIMIZE
      Page.update_all("title = '#{escape_single_quotes(page_title)}', templet_id='#{templet_id}'", "id=#{self.id}" )
      self.page_parts.create_from_content(page_content.content_without_title, templet)
      self.reload
      return self
    end

 

test:

  describe "create_from_content" do 
    it "should create page's atrributes from content" do 
      page = Page.create
      page_content = mock(PageContent, :templet_id => 1, :page_title => "page_title", :content_without_title => "content_without_title", :templet => "templet")
      PageContent.stub!(:new).with("content").and_return(page_content)
      page.stub!(:escape_single_quotes).with("page_title").and_return("page_title")
      page.page_parts.stub!(:create_from_content).with("content_without_title", "templet").and_return(nil)
      page.create_from_content("content").should == page
      page.title.should == "page_title"
      page.templet_id.should == 1
    end
  end
