Ruby on rails Rails 3中的Shoulda测试：应以：success作为响应

我在Rails 3中测试时遇到了一些问题。我目前正在将Rails2应用程序升级到Rails3。我正在使用shoulda进行测试。在我的功能测试中，我使用shoulda进行测试，GET应该能够成功响应

context "GET to :blame" do
  should "mark a song as blamed" do
    get :blame, :id => @song.id
    assert_equal Blame.count, 1
    get :blame, :id => @song.id
    assert_equal Blame.count, 2
  end
  should respond_with :success
end

在最后一行的下一行中，我在使用rake test执行功能测试时遇到以下错误：functionals：

  1) Error:
test: a visitor GET to :blame should respond with 200. (SongsControllerTest):
NoMethodError: undefined method `response_code' for nil:NilClass

我正在使用Ruby 1.9.2、Rails 3.0.3和Shoulda 2.11.3。 希望有人能帮助我

thx，

两个应块分别运行，不会请求响应，因此会出现错误。您需要在设置块中发出请求，例如：

context "GET to :blame" do
  setup do
    get :blame, :id => @song.id
  end
  should "mark a song as blamed" do
    assert_equal Blame.count, 1
  end
  should respond_with :success
end
