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 以及任何版本的 Ruby 或任何版本的 Rails。也许我错过了一些明显的东西?
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
这是自动生成的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
?
更新
这是来自我的控制器的 show 方法:
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!
