ruby-on-rails - 运行 Capybara（使用 Minitest）时未执行 Javascript

Question

运行我的测试时，javascript 没有被执行。我尝试从 :selenium 驱动程序切换到 :webkit 驱动程序，但仍然没有运气。

它在浏览器中运行良好。当测试运行并打开页面时，页面为空白

我还需要做些什么来让它在测试运行期间执行 javascript 吗？

business_integration_test.rb

require 'minitest_helper'
require 'ruby-debug'

describe "Business integration" do

  before :each do
    @business = Factory.build(:business)
    Capybara.javascript_driver = :webkit
  end

  it "Should show error if business name is blank" do
    visit admin_business_path
    fill_in 'Name', :with => ''
    click_button 'Save'
    page.save_and_open_page
    page.text.must_include("can't be blank")
  end
end

企业控制器.rb

class Admin::BusinessesController < Admin::AdminController

  def update
    @business = resource
    respond_to do |format|
      if @business.update_attributes(params[:business])
        flash[:notice] = "Your business was updated successfully."
      else
        flash[:notice] = "Your business failed to update."
      end
      format.js { render :template => "admin/businesses/edit" }
    end
  end

end

编辑.js.erb

$("#page-businesses #main").html("<%= escape_javascript(render :partial => 'edit_information') %>");
