当没有“期望”时，删除表的记录.出现.have_content.”

Question

我有一个简单的规范:

scenario "Fill the payments information for a painting", js: true do
  period = create(:period)
  painting = create(:painting, period: period, published: false)
  admin = AdminUser.create!(email: '[e-mail]', password: 'test1234')
  painting_price = create(:painting_price)
  sign_in
  visit new_painting_order_path(painting_id: painting.id, painting_price_id: painting_price.id)
  click_on "MasterCard/Visa"
  puts Painting.unscoped
  click_on "Compléter la commande"
  expect(admin.email).to have_received_an_email
end

和这样的控制器:

def create
  puts Painting.unscoped
  # ...
end

在第一个puts，我有一幅画，但在第二个，没有画。我激活了SQL跟踪，我有这个:

你可以看到，在两个puts之间有一个DISABLE TRIGGER ALL。显然，我的代码中没有这样做。

当我在Compléter la commande之后添加expect(page).to have_content("Votre commande a bien été éffectuée")时。它的工作原理。

我认为有一个问题与capybara-webkit。似乎提前清理了数据库。

你有什么好办法吗?

Answer 1

除非您正在使用机架测试驱动程序，否则capybara调用通常是异步的-它不知道单击所产生的处理何时完成。一旦spec块内的代码执行完成，它就会使用数据库清理器清理表。

通常您不会注意到这一点，因为capybara查找器方法(have_css, have_content, click_link等使用的方法)将在有限的时间内重试。你对邮件投递的检查不知道怎么做。

这个最简单的修复是你已经发现的:使用一个知道如何等待引入同步点的capybara方法。
