blogs_controller_spec.rb
require 'rails_helper' describe "Blogって書かれてるか" do describe 'Home' do specify '画面の表示' do visit root_path expect(page).to have_css('h1',text:'Blogs') end end end
試したこと

こちらを参考に、環境を設定
https://qiita.com/kazukimatsumoto/items/a0daa7281a3948701c39
試す環境が欲しかったので、route.rbにroot 'blogs#index'を設定
blogs_controller_spec.rbに試しにテスト内容を記載し、bundle exec rspecを実行
spec_helper.rbに
config.include Capybara::DSL
を記載すれば解決するという記事を発見しためして見たのですが、今度は
Failure/Error: config.include Capybara::DSL
NameError:
uninitialized constant Capybara
というエラーが出ました。
補足情報(FW/ツールのバージョンなど)
visitの記述を抜いたらどうなるのかと思い、
簡単な計算でテストしたところ、問題なく動作しました。
