如何在RSpec/Capybara测试中进行配置更改？

require 'capybara/rspec'

Capybara.configure do |config|
  config.default_driver = :selenium # 选择默认的驱动程序
  config.default_max_wait_time = 10 # 设置默认的等待时间，单位为秒
  # 其他Capybara配置项
end

module SessionHelpers
  def login_as(user)
    visit login_path
    fill_in 'Email', with: user.email
    fill_in 'Password', with: user.password
    click_button 'Login'
  end
end

RSpec.configure do |config|
  config.include SessionHelpers, type: :feature
end
