Question

我有一种我想测试的控制器方法。我有一个需要用户登录的案例。我为此目的使用Authlogic，所以我用这样的方式写了我的测试：

test "should get edit" do
  Authlogic::Session::Base.controller = Authlogic::ControllerAdapters::RailsAdapter.new(self)
  # line above was required by line below, but honestly I don't know why
  UserSession.new({email: 'my.email@gmail.com', password: 'aaaabbbb', password_confirmation: 'aaaabbbb'})

  get edit_service_url(@service)
  assert_response :success
end

测试失败，看起来我还没有登录。我想确保我的会话没有创建，所以我添加了简单的puts行：

test "should get edit" do
  Authlogic::Session::Base.controller = Authlogic::ControllerAdapters::RailsAdapter.new(self)
  UserSession.new({email: 'my.email@gmail.com', password: 'aaaabbbb', password_confirmation: 'aaaabbbb'})

  puts UserSession.find

  get edit_service_url(@service)
  assert_response :success
end

但是在添加它之后我得到了这个错误，这对我来说是完全不可理解的：

它是由什么引起的？如何正确地编写我的测试？

修改

我正在测试的代码：

class ServicesController < ApplicationController
  before_action :authorise_for_service_id, only: [:edit]

  # ...

  def edit
  end

  # ...

  private:

  # ...

    def authorise_for_service_id
      if !is_user_id_current?(Service.find(params[:id]).user_id)
        redirect_to service_path(params[:id]), notice: 'Cannot perform your action: access denied.'
      end
    end
end

module ApplicationHelper

  # ...

  def is_user_id_current?(user_id)
    return current_user && current_user.id == user_id
  end
  def current_user
    return @current_user if defined?(@current_user)
    @current_user = current_user_session && current_user_session.user
  end
  def current_user_session
    return @current_user_session if defined?(@current_user_session)
    @current_user_session = UserSession.find
  end

  # ...

end

class UserSessionsController < ApplicationController
  def new
    @user_session = UserSession.new
    respond_to do |format|
      format.html # new.html.erb
    end
  end

  # POST /user_sessions
  def create
    @user_session = UserSession.new(user_session_params)

    respond_to do |format|
      if @user_session.save
        format.html { redirect_to session[:return_to] || root_url, :notice => 'Login Successful!' }
      else
        format.html { render :action => "new" }
      end
    end
  end

  # DELETE /user_sessions/1
  def destroy
    @user_session = UserSession.find
    @user_session.destroy

    respond_to do |format|
      format.html { redirect_to session[:return_to] || root_url, :notice => 'Goodbye!' }
    end
  end

private
  def user_session_params
    params.require(:user_session).permit(:email, :password)
  end
end
