在Shoulda測試中使用機械師登錄時出錯

Question

我在測試中正確使用機械師和Shoulda時遇到了一些麻煩。

這裏是我的測試：

context "on POST method rating" do 
p = Product.make 
u = nil 
setup do 
    u = login_as 
    post :vote, :rating => 3, :id => p 
end 

should "set rating for product to 3" do 
    assert_equal p.get_user_vote(u), 3 
end 

這是我的藍圖：

Sham.login { Faker::Internet.user_name } 
Sham.name { Faker::Lorem.words} 
Sham.email { Faker::Internet.email} 
Sham.body { Faker::Lorem.paragraphs(2)} 

User.blueprint do 
login 
password "testpass" 
password_confirmation { password } 
email 
end 

Product.blueprint do 
name {Sham.name} 
user {User.make} 
end 

而我的驗證測試助手：

def login_as(u = nil) 
    u ||= User.make() 
    @controller.stubs(:current_user).returns(u) 
    u 
end 

我得到的錯誤是：

     from ./test/functional/products_controller_test.rb:24 

我無法弄清楚我在做什麼錯了......我在我的user_controller測試中用我的auth（Authlogic）測試了login_as。

任何指針正確的方向將不勝感激！

我已經得到了部分解決。我已經解決了以上問題，但should_redirect_to功能仍然給我適合...

這是我的新的測試代碼：

context "on POST method rating" do 

    setup do 
    @u = login_as 
    @p1 = Product.make 
    @p2 = Product.make # Make a second product that we'll show after rating the first 
    post :vote, :rating => 3, :id => @p1 
    end 

    should "set rating for product to 3" do 
    assert_equal @p1.get_user_vote(@u), 3 
    end 

    should_redirect_to("product page") {show_product_url(:id => @p2)}  
end 

而我的新的錯誤：

response to be a redirect to <http://test.host/products/555660218> but was a redirect to <http://test.host/products>. 

任何想法從哪裏走？

您的控制器是否重定向到products_url？

備註：對於任何需要唯一性的驗證，您都不應該使用隨機數據（Faker）。這就是Factory Girl的序列。我認爲機械師有類似的東西。
