当没有'expect .. to .. have_content..`时，删除表的记录

我有一个像这样的简单规范：

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: 'admin@example.com', 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

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：

您可以看到，在两个puts之间，它会DISABLE TRIGGER ALL。显然，我的代码中没有任何内容可以做到这一点。

当我在expect(page).to have_content("Votre commande a bien été éffectuée")之后添加Compléter la commande时。它有效。

我认为capybara-webkit存在问题。它似乎在时间之前清理数据库。

你有想法解决它吗？

1 个答案:

答案 0 :(得分：0)

除非你使用机架测试驱动程序，否则capybara调用通常是异步的 - 它不知道点击产生的处理何时完成。只要在spec块中执行代码完成，它就会使用数据库清理程序来清理表。

通常你没有注意到这一点，因为水豚探测器方法（由have_css，have_content，click_link等使用的方法）将在一段有限的时间内重试时间。您对电子邮件递送的检查并不知道如何执行此操作。

这个最简单的修复是你已经找到的：使用其中一个知道如何等待引入同步点的capybara方法。
