在Shoulda测试中使用Machinist登录时出错

Question

在我的测试中，我在正确使用Machinist和Shoulda时遇到了一些麻烦。

这是我的测试：

 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

这是我的蓝图：

 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

和我的身份验证测试助手：

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

我得到的错误是：

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

我不知道我到底做错了什么。我已经在我的user_controller测试中使用我的身份验证(Authlogic)测试了login_as。

任何指向正确方向的指针都将不胜感激！

我有一个部分解决方案..。我已经解决了上面的问题，但是should_redirect_to函数仍然让我不知所措。

这是我的新测试代码：

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

我的新错误是：

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

你有什么想法吗？

Answer 2

您的控制器是否重定向到products_url？

附注:对于任何需要唯一性的验证，都不应该使用随机数据(Faker)。这就是“工厂女孩”系列的用处。我猜Machinist也有类似的东西。
