Rspec Capybara测试与Ajax调用未更新记录 [英] Rspec Capybara test with ajax call not updating record

问题描述

我有一个表单，其中当用户提交带有单个名称字段的ajax表单时，将创建一个属于Template对象的记录。所有这些都可以手动正常运行，但是由于某种原因，当我通过rspec测试它时，它告诉我未创建关联。为什么模板对象在这里没有更新？

I have a form where when a user submits an ajax form with a single name field, a record is created that belongs to a Template object. This all works fine manually, but for some reason when I test this via rspec its telling me that the association was not created. Why isn't the template object updated here?

describe "edit page" do
  before(:each) do
    visit edit_admin_template_path(template)
  end

  context "form sections", js: true do  
    it "allows admin to create one" do
      find("#btn-add-section").click
      within('#new_form_section') do
        fill_in 'Name', with: "Personal Info"
        click_button "Create Section"
      end
      expect(template.form_sections.length).to eq(1)
    end
  end
end

这是我得到的失败

Failure/Error: expect(template.form_sections.length).to eq(1)

   expected: 1
        got: 0

   (compared using ==)

更新：刚在rspec输出中注意到了这一点

UPDATE: just noticed this in the rspec output

An error occurred in an after hook
    ActionView::Template::Error: undefined method `form_sections' for nil:NilClass

所以它告诉我模板对象不存在，那么以后可以比较它吗？

so its telling me that the template object does not exist, then its able to compare it afterwards?

更新2：因此，问题似乎出乎人们的意料，它是在capybara中等待ajax调用完成。我将其添加到规范中，现在可以正常工作，显然我需要将其重新映射为更好的助手之类的东西。

UPDATE 2: So it appears that the issue is waiting for the ajax call to complete in capybara, before expecting. I added this to the spec and it now works, obviously I need to refacotr this to something better like a helper

it "allows admin to create one" do
  find("#btn-add-section").click
  within('#new_form_section') do
    fill_in 'Name', with: "Personal Info"
    click_button "Create Section"
  end
  sleep(10) #this waits for the request to complete
  expect(template.form_sections.length).to eq(1)
end

推荐答案

关键是告诉RSpec等待在进行任何期望之前，ajax调用要完成。这是我使用的解决方案的好文章：

The key is telling RSpec to wait for the ajax call to complete before doing any expectations. This is a great post on the solution that I used:
