SPEC - 人々が見たい場合。

require 'rails_helper' 

RSpec.describe TopicPost, :type => :model do 
    it "checks if twitter handle exists" do 
    professional_safety = TopicPost.new(topic_id: "professional_safety", pub_date: "5a612420-21e2-11e6-bdf4-0800200c9a66",  author_id: 1, id: 1, message: "test", twitter_handle: "blau") 
    professional_safety.save() 
    expect(TopicPost.all.count).to eq(0) 
    end 
end 

私は実際にこれを理解する手がかりがありません。私はcequel、rspec、またはgemの問題かどうかはわかりません。誰も私がこれを理解するのを助けることができる？

ありがとうございました。

あなたのconfig/cequel.ymlには、そのようなテストデータベースが含まれていることを確認する必要があります。
