如何在请求规范中存根 ApplicationController 方法 [英] How to stub ApplicationController method in request spec

问题描述

我需要在 Rspec/capybara 请求规范中存根 current_user 方法的响应.该方法在 ApplicationController 中定义并使用 helper_method.该方法应该简单地返回一个用户 ID.在测试中，我希望此方法每次都返回相同的用户 ID.

I am needing to stub the response of a current_user method in an Rspec/capybara request spec. The method is defined in ApplicationController and is using helper_method. The method should simply return a user id. Within the test, I'd like this method to return the same user id each time.

或者，我可以通过在规范中设置 session[:user_id] 来解决我的问题(这是 current_user 返回的内容)......但这似乎不是要么工作.

Alternatively, I could fix my problem by setting session[:user_id] in the spec (which is what current_user returns)... but that doesn't seem to work either.

这两种都有可能吗?

这是我得到的(它不起作用.它只是运行普通的 current_user 方法).

Here is what I've got (it is not working. It just runs the normal current_user method).

require 'spec_helper'

describe "Login" do

   before(:each) do
     ApplicationController.stub(:current_user).and_return(User.first)
   end

  it "logs in" do
    visit '/'
    page.should have_content("Hey there user!")
  end

end

也不起作用:

require 'spec_helper'

describe "Login" do

  before(:each) do
    @mock_controller = mock("ApplicationController") 
    @mock_controller.stub(:current_user).and_return(User.first)
  end

  it "logs in" do
    visit '/'
    page.should have_content("Hey there user!")
  end

end

如果您尝试存根的方法是实例方法(最有可能)而不是类方法，那么您需要使用:

If the method you're trying to stub is an instance method (most likely) and not a class method then you need use:

ApplicationController.any_instance.stub(:current_user)
