RSpec + Factory_Girl查看測試

Question

再一次，似乎卡住了簡單的視圖測試。這裏的代碼：

require 'spec_helper' 

describe "posts/show.html.erb" do 
    setup do 
    @post = Factory(:post) 
    end 

    it "should not render a canonical link rel" do 
    get :show, :id => @post.id 
    response.should_not have_tag("link[rel=?]", "canonical") 
    end 
end 

當我從控制檯工廠（：後），沒有問題，完美地創建它。但是當我在命令行運行這個時，我得到以下內容：

rspec spec/views/posts/show.html.erb_spec.rb 
F 

Failures: 

    1) posts/show.html.erb should not render a canonical link rel 
    Failure/Error: get :show, :id => @post.id 
    RuntimeError: 
     Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id 
    # ./spec/views/posts/show.html.erb_spec.rb:11

1 example, 1 failure 

任何想法我失蹤？

Answer 1

你想用before each：

before(:each) do 
    @post = Factory(:post) 
end 

或

before do 
    @post = Factory(:post) 
end 

的簡寫。

而不是設置塊。
