RSpec 集成测试未按预期使用 ajax/js 表单提交进行工作

Question

由于某种原因，此测试失败了，这与测试必须发送电子邮件有关。它没有将电子邮件存储在数组中，我还有另一个几乎相同的测试，唯一的区别是它不使用 ajax/js 进行表单提交，并且测试顺利通过并且电子邮件到达数组。

有什么想法吗？

控制器：

class UsersController < ApplicationController

  def new
    @user = User.new
  end

  def create
    @user = User.new(params[:user])     
    respond_to do |format|
      if @user.save 
        UserMailer.join_confirmation(@user).deliver
        format.js   { render :js => "window.location = '#{temp_success_path}'" }

      else

        format.html { render :new }  
        format.js   { render :form_errors }
      end
    end
  end


end

          click_button "join_submit"
          response.should render_template 'users/new'
          response.should have_selector :div, :id => "error_explanation"
          last_email.should be_nil
        end.should_not change User, :count

    end

          last_email.to.should include user.email
          response.should render_template :js => "window.location = '#{temp_success_path}'"

        end.should change User, :count

要测试js，您必须在代码中明确声明它。
