Question

我为凤凰应用程序添加了以下测试：

navigate_to("/")

registration_page_link = find_element(:class, "header__button__register")
registration_page_link |> click()

form                   = find_element(:class, "form__register")
email_field            = find_within_element(form, :class, "input--email")
first_name_field       = find_within_element(form, :class, "input--first_name")
last_name_field        = find_within_element(form, :class, "input--last_name")
password_field         = find_within_element(form, :class, "input--password")
confirm_password_field = find_within_element(form, :class, "input--confirm_password")
submit_button          = find_within_element(form, :class, "form__submit")

email_field            |> fill_field("john.doe@email.com")
first_name_field       |> fill_field("John")
last_name_field        |> fill_field("Doe")
password_field         |> fill_field("12345678")
confirm_password_field |> fill_field("12345678")
submit_button          |> submit_element()

alert      = find_element(:class, "alert--success")
alert_text = visible_text(alert)
name       = find_element(:class, "header__user_name")
name_text  = visible_text(name)

assert alert_text  == "Congratulations John! You have successfuly registered."
assert name_text   == "John D."
assert_raise Hound.NoSuchElementError, ~r/No element found for class/, fn ->
  find_element(:class, "header__button__register")
end

它测试用户是否可以使用有效凭证进行注册如果我注释掉最后一个断言，测试需要0.7秒才能运行如果我单独尝试上一个断言，则测试需要6.1秒才能运行。

为什么这个断言运行得如此之慢？有没有更好的方法来测试元素不再出现在页面上？

Answer 1

tf.inv的第三个参数是默认为find_element的重试次数，是Hound尝试查找元素with a gap of retry_time milliseconds which defaults to 250的次数。由于早期的5调用已经加载了页面，因此您可以通过将重试次数设置为find_element来加速此断言：
