Capybara 的基本规格失败 / RSpec 3 / Rails 4 (have_content)

Question

我对 RSpec 和 Capybara 比较陌生，我正在制作一个基本的漫画书数据库应用程序来试验它们。由于某种原因，测试失败了（尽管当我手动创建漫画书时，我看到了确认文本）。

这是测试：

require 'spec_helper.rb'

feature 'Creating Comic Books' do
  scenario 'can create a comic book' do
    visit '/'

    click_link 'New Comic book'

    fill_in 'Title', with: 'Batman'
    fill_in 'Publisher', with: 'DC'
    fill_in 'Issue number', with: 32
    fill_in 'Summary', with: 'What a nice comic book'

    expect(page).to have_content("Comic book was successfully created.")
  end
end

下面是失败消息和回溯：

1) Creating Comic Books can create a comic book
     Failure/Error: expect(page).to have_content("Comic book was successfully created.")
       expected to find text "Comic book was successfully created." in "Toggle navigation Project name Home About Contact New Comic Book Title Publisher Issue number Summary What a nice comic book Back"

我试过同时使用 capybara-webkit 和 selenium，无论如何我都会收到错误。

Answer 1

您在测试中没有点击提交表单的按钮。

填写表格后可能会是click_button "Create Comic Book"这样的东西。
