Question

我正在将Rails 2.3.5应用升级到Rails 3.0.3。但我的集成测试不工作。我收到了这个错误：

NoMethodError: undefined method `content_type' for nil:NilClass

归咎于

assert_select "input#artist.title.unsolved", 1

我的webrat的test_helper.rb看起来像这样：

require "webrat"
require 'webrat/core/matchers'
include Webrat::Methods

Webrat.configure do |config|
  config.mode = :rack
end

我正在使用shoulda 2.11.3和webrat 0.7.3进行测试。我读了， webrat和shoulda与Rails3兼容。

任何人都知道如何解决这个问题？

谢谢！ TUX

ADDITION ：

似乎NoMethodError出现在shoulda中，而不是来自Webrat，如标题中所述。这是跟踪：

NoMethodError: undefined method `content_type' 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'

这是assert_select周围的整个块上下文：

class SongIntegrationTest < ActionController::IntegrationTest
  context "a visitor" do
    context "solving a song" do
      setup do
        @song = Song.make
        visit song_path(@song)
      end

      should "have two guess fields" do
        assert_select "input#artist.title.unsolved", 1
        assert_select "input#title.title.unsolved", 1
      end

也许在使用Shoulda的Rails 3中，assert_select不再可用。希望可以有人帮帮我！ THX！

有一个webrat的分支可以在https://github.com/joakimk/webrat处使用rails3。在某些时候它应该被拉入主分支。 rails 2.3目前仍然很受欢迎。

使用webrat和Rails3进行集成测试
