ruby-on-rails - capybara ::ElementNotFound:找不到字段

Question

我刚刚学习功能规范，但遇到了一个我不太明白的问题。 Capybara::ElementNotFound: 当我尝试运行测试时。这很奇怪，因为我逐字逐句地遵循模板，但我仍然收到此错误。我需要一些帮助!为了清楚起见，这是我的代码和错误。

测试

require "rails_helper"

RSpec.feature "Create a subscriber" do
 scenario "Customer can sign up as a subscriber" do
  visit "/subscribers/new"

  user = User.create!(email: "user@example.com", password: "password")
  fill_in "Email", with: "user@example.com"
  fill_in "Password", with: "password"
  click_button "Sign in"

  fill_in "first_name", with: 
  fill_in "last_name", with: 
  fill_in "email", with:
  fill_in "phone_number", with: "8269338"

  expect(page).to have_content("Subscriber Has Been Successfully Created")
 end
end

查看

  <%= form_for @subscriber do |form| %>
  <div class="form-group">
  <p>
  <%= form.label :first %>
  <%= form.text_field :first_name %>
  </p>
  <p>
  <%= form.label :last %>
  <%= form.text_field :last_name %>
  </p>
  <p>
  <%= form.label :email %>
  <%= form.text_field :email %>
  </p>
  <p>
  <%= form.label :phone %>
  <%= form.text_field :phone_number %>
  </p>
 </div>
<%= form.submit "Sign Up", class: "btn btn-primary" %>

错误

Answer 1

字段的 ID 都将以 subscriber_ 为前缀 - 尝试将 fill_in "first_name", with: "Cam" 更改为 fill_in "subscriber_first_name", with : "Cam" 看看是否能解决问题。
