Elixir Hound 等待页面加载 [英] Elixir Hound wait for page to load

问题描述

我正在提交一个登录表单，然后尝试使用 elixir/hound 捕获 HTML.提交后，我运行 page_source 并一无所获.如果我等待一秒钟(页面完成加载)，然后我会取回 html.

I'm submitting a login form and trying to capture the HTML afterwards using elixir / hound. After submitting I run page_source and get nothing. If I wait for a second (for the page to finish loading) then I get back the html.

有没有办法让 hound 等到页面加载完成?

Is there a way to make hound wait till the page is finished loading?

我目前正在做::timer.sleep(2000) 作为解决方法，希望有更好的方法:/

I'm currently doing: :timer.sleep(2000) as a work around, hoping for a better way :/

推荐答案

我就是这样做的:

创建一个函数，每 100 毫秒重复检查一次测试条件，在这种情况下，我正在等待特定文本出现visible_page_text

Create a function that repeatedly checks for a test condition every 100ms, in this case I'm waiting for particular text to appear by using visible_page_text

@tag timeout: 6000
test "My Test" do
  assert wait_for(fn -> Regex.match?(~r/Success/, visible_page_text()) end)
end

def wait_for(func) do
  :timer.sleep(100)
  case func.() do
    true -> true
    false -> wait_for(func)
  end
end
