我在使用 rspec 和设计测试用户身份验证时遇到问题。

这是我的代码：

require 'rails_helper'

describe UsersController, :type => :controller do

  let(:user) { User.create!(email: '1@test.com', password: '123456') }

  describe 'GET #show' do

    context 'User is logged in' do
      before 
        sign_in user
        get :show 
      end

      it "loads correct user details" do
        expect(assigns(:user)).to eq user
      end

    end

    context 'No user is logged in' do
      it 'redirects to login' do
        get :show, id: user.id
        expect(response).to redirect_to(root_path)
      end
    end
  end

end

当我在终端上运行 rspec 时出现此错误：

/Users/joao1/.rvm/gems/ruby-2.3.0/gems/activesupport-5.0.0.1/lib/active_support/dependencies.rb:287:in `load': /Users/joao1/Desktop/nameofapp/spec/controllers/users_controller_spec.rb:29: syntax error, unexpected keyword_end, expecting end-of-input (SyntaxError)

我该如何解决这个问题并有效地测试我的用户身份验证？

【解决方案1】：

错误消息是由于程序中的拼写错误导致的，它与 do end 块不匹配。仔细观察，我发现您缺少 before 块中的 do 语句。改成：

 before do
   sign_in user
   get :show 
 end

谢谢大卫，就是这样。
我的代码失败了，但至少测试运行了。非常感谢
