使用 mocha 打桩助手
it "should have edit button if user has permission to edit" do
EntitiesHelper.stubs(:permission_to_edit_entity?).returns(true)
get :index
@entities[0..3].each do |entity|
response.should have_selector("form",
:method => "get",
:action => "/entities/edit/#{entity[:id]}") do |form|
form.should have_selector("input", :value => "Edit")
end
end
end
我正在尝试编写一个简单的测试用例，用于测试用户是否有权编辑是否显示编辑按钮。我正在尝试为此使用存根。然而，它似乎不起作用。如果存根有效，输出视图不会在每个实体旁边显示我所期望的编辑按钮。我是摩卡和存根的新手 - 我在这里做错了什么？
谢谢！

I am trying to write a simple test case which tests that an edit button is showed if the user has permission to edit. I am trying to use stubbing for this. However, it doesn't seem to work. The output view does not show the edit button next to every single entity which I would expect if the stubbing works. I am new to mocha and stubbing - I am doing something wrong here?
Thanks!

我假设 EntitiesHelper 是一个普通的旧 Rails 助手，它混合到控制器中 - 因此它的所有实例方法（例如permission_to_edit_entity？ ）都可供控制器使用，并且视图具有访问这些辅助方法（通过控制器）...所以您可以在控制器上存根该方法：
在这种特殊情况下，我什至会考虑将存根更改为模拟，因为您希望调用该方法（尽管您是测试按钮的存在，很高兴知道流程没有按预期发生）：
但这当然是有争议的，无论如何你都应该没问题......
I assume
EntitiesHelperis a plain-old rails helper that gets mixed into the controller - thus all it's instance methods (such aspermission_to_edit_entity?) are available to the controller and views have access to these helper methods (via the controller) ... so You might stub the method on the controller :in this particular case I would even consider changing the stub to mock since You expect the method to be called (although You're testing the button presence, it's good to know that the flow did not happen as expected) :
but this of course is debatable and You should be fine either way ...
