我在 Rails 3 中进行测试时遇到了一些麻烦。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，我正在使用 shoulda 进行测试，GET 应该成功响应

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:functionals 执行功能测试时遇到以下错误：

  1) Error:
test: a visitor GET to :blame should respond with 200. (SongsControllerTest):
NoMethodError: undefined method `response_code' for nil:NilClass
    /Users/23tux/.rvm/gems/ruby-1.9.2-p136@rails3/gems/activesupport-3.0.3/lib/active_support/whiny_nil.rb:48:in `method_missing'

我正在使用 Ruby 1.9.2、Rails 3.0.3 和 Shoulda 2.11.3。希望可以有人帮帮我。

谢谢，晚礼服

这两个应该块是分开运行的，不会对 respond_with 提出请求，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
