我阅读了以下有关使用Rspec进行功能测试的文章：
https://about.futurelearn.com/blog/how-we-write-readable-feature-tests-with-rspec/
我在安装capybara gem后尝试了以下操作并出现错误：
=> schedule_kaya_spec.rb:9:in `<top (required)>': undefined method `feature' for RSpec:Module (NoMethodError)
这是我的代码：
RSpec.feature "Create recurring event and get slack via cron next day" , :type => :feature do
scenario "User creates a daily recurring event at 10AM PST" do
given_a_user_has_created_a_recurring_slack_event_at_10_pst
when_the_time_passes_10_pst_the_next_day
then_send_a_slack_message
and_update_next_occurrence_for_the_next_day
end
def given_a_user_has_created_a_recurring_slack_event_at_10_pst
# set time to 10AM PST
Time.zone = "America/Los_Angeles"
Chronic.time_class = Time.zone
Timecop.freeze(Chronic.parse("march 1, 2014 at 10AM"))
user_input = "xtest create recurring event at 10 AM PST everyday with keyword test reminder keyword"
bot_client_id = 'test-client-id'
bot_response = BotResponse.new(bot_client_id, user_input, "1000")
bot_response.run
end
问题：
1）如何使用下面的方法创建功能/场景测试？
2）有没有办法让feature更像描述，并且具有嵌套场景的多个功能？
