当需要当前密码时，如何使用Capybara测试更新帐户信息？

# 导入所需的库
require 'capybara'
require 'capybara/dsl'
require 'capybara/rspec'

# 配置Capybara
Capybara.run_server = false
Capybara.current_driver = :selenium
Capybara.app_host = 'http://your_app_url.com'

# 定义测试用例
describe '更新帐户信息' do
  include Capybara::DSL

  before(:each) do
    # 登录到应用程序
    visit '/login'
    fill_in 'username', with: 'your_username'
    fill_in 'password', with: 'your_password'
    click_button '登录'
  end

  it '应该成功更新帐户信息' do
    # 导航到帐户设置页面
    visit '/account/settings'

    # 输入当前密码
    fill_in 'current_password', with: 'your_current_password'

    # 输入新的帐户信息
    fill_in 'new_email', with: 'new_email@example.com'
    fill_in 'new_password', with: 'new_password'
    fill_in 'confirm_password', with: 'new_password'

    # 提交表单
    click_button '保存'

    # 验证更新成功的提示信息
    expect(page).to have_content '帐户信息已成功更新'
  end
end
