# This file is copied to spec/ when you run 'rails generate rspec:install'
require 'spec_helper'
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
# Prevent database truncation if the environment is production
abort("The Rails environment is running in production mode!") if Rails.env.production?
require 'rspec/rails'
# Add additional requires below this line. Rails is not loaded until this point!

require'capybara/rspec'  # この1行を追加

フィーチャーテストの実施

スペックファイルの作成

rails g rpsec:feature projects

require 'rails_helper'

RSpec.feature "Projects", type: :feature do
  scenario "user create a new project" do
    user = FactoryBot.create(:user)

    visit root_path
    click_link "Sign in"
    fill_in "Email", with: user.email
    fill_in "Password", with: user.password
    click_button "Log in"
