Rspec不记录用户进行测试

Question

我试图在成功时测试我的控制器的'CREATE'方法以重定向到root_url。

# templates_controller.rb 

require 'open-uri' 

class TemplatesController < ApplicationController 
    before_filter :authenticate_user! # Authenticate for users before any methods are called 

    def create 
    @template = current_user.templates.build(params[:template]) 
    if @template.save 
     flash[:notice] = "Successfully uploaded the file." 

     if @template.folder #checking if we have a parent folder for this file 
     redirect_to browse_path(@template.folder) #then we redirect to the parent folder 
     else 
     redirect_to root_url 
     end 
    else 
     render :action => 'new' 
    end 
    end 
end 

这是我的规格文件

describe "POST 'create'" do  

    let(:template) { mock_model(Template) } 

    before(:each) do 
    controller.stub_chain(:current_user, :templates, :build) { template } 
    end 

    context "success" do 
    before(:each) do 
     template.should_receive(:save).and_return(true) 
     post :create 
    end 

    it "sets flash[:notice]" do 
     flash[:notice].should == "Successfully uploaded the file." 
    end 

    it "redirects to the root_url" do 
     response.should redirect_to(root_url) 
    end 

    end 
end 

这是错误，我得到

TemplatesController POST 'create' success sets flash[:notice] 
    Failure/Error: flash[:notice].should == "Successfully uploaded the file." 
    expected: "Successfully uploaded the file." 
      got: nil (using ==) 
    # ./spec/controllers/templates_controller_spec.rb:35:in `block (4 levels) in <top (required)>' 

12) TemplatesController POST 'create' success redirects to the root_url 
    Failure/Error: response.should redirect_to(root_url) 
    Expected response to be a redirect to <http://test.host/> but was a redirect to <http://test.host/users/sign_in> 
    # ./spec/controllers/templates_controller_spec.rb:39:in `block (4 levels) in <top (required)>' 

13) Template should be valid 
    Failure/Error: Template.new.should be_valid 
    expected valid? to return true, got false 
    # ./spec/models/template_spec.rb:5:in `block (2 levels) in <top (required)>' 

试验显然没有登录，因为它重定向到http://test.host/users/sign_in用户。我如何获得rspec来登录用户？

我不完全清楚什么#authenticate_user！是干什么的，但我的猜测是你的嘲弄与以上认证的某一部分的顶部：

controller.stub_chain(:current_user, :templates, :build) { template } 

另一种可能是你正在因为另一个过滤器更早重定向，例如重定向如果ActiveRecord的过滤器:: NOTFOUND 。我建议用真正的电话代替嘲笑/期望，直到你找出问题。

您也可以看看Devise，特别是Devise :: TestHelpers＃sign_in，以获取身份验证测试的灵感。
