RSpec / Rails - 如何测试ApplicationController中的方法是否被调用（当我测试子类控制器时）？

Question

Title says it all.

I have a controller action in which I do some stuff, then call a method that is defined in ApplicationController .

How do I test that it was called?

controller.should_receive(:the_method_name) doesn't work.
ApplicationController.should_receive(:the_method_name) doesn't work.

What's the proper syntax?

Thanks.

Answer 1

我想你可以使用匿名控制器来测试你的ApplicationController，查看文档。

Answer 2

Using the AnonymousController as Gerep suggested and calling controller.should_receive(:the_method_name) should do it.

The position within the test is important to let the test pass successfully. To give you an example:

describe 'my test' do
  before do
    controller.should_receive(:the_method)
    get :action
  end
  it { should render_template(:your_template) }
end

This example should pass and tests also the call of :the_method .
