有人可以向我描述 RSpec 2 在这方面的作用吗? [英] Can someone describe to me what RSpec 2 is doing in this?

问题描述

我一直在尝试深入研究 RSpec 2，但其自动生成的控制器规范不适用于任何版本的 RSpec 2 和任何版本的 Ruby 或任何版本的 Rails.也许我遗漏了一些明显的东西?

I have been attempting to dive into RSpec 2 but its auto generated controller specs do not work for any version of RSpec 2 with any version of Ruby or any version of Rails. Maybe I'm missing something obvious?

def mock_category(stubs={})
  @mock_category ||= mock_model(Category, stubs).as_null_object
end

describe "GET show" do
  it "assigns the requested category as @category" do
    Category.stub(:find).with("37") { mock_category }
    get :show, :id => "37"
    assigns(:category).should be(mock_category)
  end
end

这是从rails g scaffold Category

RSpec 返回:

Failures:
   1) CategoriesController GET show assigns the requested category as @category
    Failure/Error: assigns(:category).should be(mock_category)
    expected Category_1002, got nil
    # ./spec/controllers/categories_controller_spec.rb:21
    # /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:239:in `inject'

为什么这个模拟/存根返回 nil ?

Why is this mock/stub returning nil ?

更新

这是来自我的控制器的 show 方法:

This is from my controller's show method :

def show
   @category = Category.find(params[:id])

  respond_to do |format|
    format.html # show.html.erb
    format.xml  { render :xml => @category }
  end
end

谢谢！

推荐答案

RSpec 在 Rails3 beta 和 RSpec 2 beta.10 到 Rails3 版本和 RSpec 2 beta.20 之间有一些严重的冲突.

RSpec has some serious conflicts between Rails3 beta, and RSpec 2 beta.10 to Rails3 release, and RSpec 2 beta.20.

我尝试复制和粘贴脚手架之间的差异，但我通过删除所有规格并重新生成它们来完全清理现场.卸载 haml，并且只安装 Rails 3 的 haml-rails.

I tried copying and pasting the differences between the scaffolds, but I cleared up the sitation entirely by deleting all the specs, and regenerating them. Uninstalling haml, and installing only haml-rails for rails 3.

现在运行所有规范.
