###前提・実現したいこと
Railsのチュートリアルを見ながら、勉強中の初心者です。
初歩的な質問かもしれませんが、Rails test で、単体テストを行った際、テストに記載していない内容のエラーが発生し、エラーの原因がわからず困ってます。
どのソースが実行されているのか（どのソースでエラーになっているのか）確認する方法を教えて欲しいです。
###発生している問題・エラーメッセージ
rails test test/controllers/users_controller_test.rb
を実行したときに、以下のエラーが発生してます。
bash

INSERTを発行するテストは行っていないにも関わらず、INSERTのエラーが発生しています。
テスト範囲を、test/controllers/users_controller_test.rb で指定しており、このソース内には、CREATEのイベント発行は行っていません。
###該当のソースコード
test/controllers/users_controller_test.rb
Ruby
1 require 'test_helper' 2 3 class UsersControllerTest < ActionDispatch::IntegrationTest 4 setup do 5 @user = users(:one) 6 end 7 8 test "should get index" do 9 get users_path 10 assert_response :success 11 end 12 end
config/routes.rb
Ruby
1 Rails.application.routes.draw do 2 resources :projects 3 resources :testids 4 get 'sessions/new' 5 6 root 'static_pages#home' 7 get '/home', to: 'static_pages#home' 8 get '/signup', to: 'users#new' 9 get '/login', to: 'sessions#new' 10 post '/login', to: 'sessions#create' 11 delete '/logout', to: 'sessions#destroy' 12 13 resources :users 14 15 # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html 16 end
###試したこと
1 8行目〜11行目をコメントアウトしてテストをすると、エラーは出ず、何も処理がされずに終了します。
bash
Running via Spring preloader in process 815 Run options: --seed 48142 # Running: Finished in 0.001560s, 0.0000 runs/s, 0.0000 assertions/s. 0 runs, 0 assertions, 0 failures, 0 errors, 0 skips
2 test/controllers 内の他のテストファイルをコメントアウトしても状況は変わりませんでした。
