私はプログラミングに非常に慣れていないので、このチュートリアルを読み進めようとしています。この章の最後にある演習用に独自のコードを作成することを除いて、与えられたコードに従いました。私は今このエラーで立ち往生しています。
Failures:
1) Authentication authorization for non-signed-in users when attempting to visit a protected page after signing in should render the desired protected page
Failure/Error: page.should have_selector('title', text: 'Edit user')
expected css "title" with text "Edit user" to return something
