Rails如何测试方法使用Rspec接收块参数

Question

Lets say I have this in application controller:

class ApplicationController < ActionController::Base

    def example(&block)
        ...code here
    end
end

and this in another controller:

class OtherController < ApplicationController

    def index
        example { some_text("irrelevant_text") }
    end

    private

    def some_text var
        "#{var}_string"
    end
end

I want to test that when calling the index action example method gets called with the irrelevant_text_string argument.

Something like:

describe 'index' do
    it 'should call example' do
        controller.should_receive(:example).with("irrelevant_text_string")
        get :index
    end
end

But this isn't working. I keep getting

received :example with unexpected arguments
expected: ("irrelevant_text_string")
          got: (no args)

Why does it say no args?
Any help will be appreciated

因为您要传递一个块，而不是一个参数。
