Rspec的测试，呼叫控制器方法获得NoMethodError

Question

所以我只是试图调用从用户控制器log_in方法在RSpec中作为

it "should get the index page" do 
    @user = User.new({ :email => "[email protected]" }) 
    log_in(@user) 
    get 'index' 
    response.should be_success 
end 

我得到的结果是一样

1) EmployeesController GET 'index' should get the index page 
    Failure/Error: log_in(user) 
    NoMethodError: 
    undefined method `log_in' for #<RSpec::Core::ExampleGroup::Nested_1:0x4ac0328> 
    # ./spec/controllers/employees_controller_spec.rb:11:in `user_log_in' 
    # ./spec/controllers/employees_controller_spec.rb:16:in `block (2 levels) in <top (required)>' 

可有人帮帮我？由于

这里是log_in方法是在UserController的

def log_in(user) 
    session[:current_user] = user.id 
    end

如果你要拨打的控制器上的方法在一个RSpec控制器测试，你可以使用以下。

subject.send(:log_in,@user) 

它应该调用该方法。我不知道这是否是最佳做法。更好的方法是按照BurmajaM的建议存储logged_in方法。

你为什么不存根LOGGED_IN？或者你的方法是什么。登录不是这个规范的目标，所以存根！这是一个简单的例子，我如何符合规范具有的before_filter控制器操作：

class MyController < ApplicationController 
    before_filter :logged_in? 

    def index 
    end 
end 



describe MyController do 
    describe "GET 'index'" do 
    context "when not logged in" 
     # you want to be sure that before_filter is executed 
     it "requires authentication" do 
     controller.expects :logged_in? 
     get 'index' 
     end 
     # you don't want to spec that it will redirect you to login_path 
     # because that spec belongs to #logged_in? method specs 
    end 
    context "when authenticated" do 
     before(:each) { controller.stubs :logged_in? } 
     it "renders :index template" do 
     get 'index' 
     should render_template(:index) 
     end 
     it "spec other things your action does when user is logged in" 
    end 
    end 
end
