如何在不测试视图的情况下测试 sinatra (padrino) 控制器？

有什么好的方法可以用 rspec 测试控制器吗？实际上，我正在使用rack/test测试完整的输出（包括渲染的视图）。

以以下最小控制器为例：

MyApp.controllers :cool_controller do

  get :index do
    some_var = DateTime.now
    render 'some_view', :locals => { :dont_know => nil, :some_var => some_var }
  end

end

测试本地哈希中的值是否像我期望的那样的最佳选项是什么？

is there any good way to test a controller with rspec? Actually, I'm testing the complete output (including the rendered view) with rack/test.

Take the following minimal controller for example:

MyApp.controllers :cool_controller do

  get :index do
    some_var = DateTime.now
    render 'some_view', :locals => { :dont_know => nil, :some_var => some_var }
  end

end

What would be the best option to test, that the values in the locals hash are like I expect them to be?

对于这种情况，您似乎想测试：
a) DateTime.now 为您提供一个有效值 - 直接使用经典 rspec 进行测试。
b) var some_var 被传递给渲染，但这很简单。

听起来您可能实际上想单独测试视图。像这样的东西（未经测试）：

it 'shows the time now' do
    right_now = DateTime.now
    engine = Haml::Engine.new(IO.read('some_view.haml'))
    rendered = engine.render(Object.new, :@some_var => right_now)
    rendered.should have_css('ul#some_var li', :text => right_now)
end

For this case, it seems you want to test:
a) DateTime.now gives you a valid value - test that directly using classical rspec.
b) the var some_var is passed to render, but that is trivial.

It sounds like you might actually want to test the view in isolation. Somthing like this (untested):

it 'shows the time now' do
    right_now = DateTime.now
    engine = Haml::Engine.new(IO.read('some_view.haml'))
    rendered = engine.render(Object.new, :@some_var => right_now)
    rendered.should have_css('ul#some_var li', :text => right_now)
end
