Ruby on rails Capybara Ruby On Rails登录

我一直试图让用户登录能够工作，但没有运气。请帮助我更好地理解水豚和rspec，我对这方面还比较陌生

# User Behavior

describe User do 
  it "Can login" do
    visit root_path
    click_on "Login"
    expect(page).to have_text("Login to your account")
    within ".simple_form" do
        fill_in "Email", with: "user@test.com"
        fill_in "Password", with: 'password'
        click_on "Log In"
        subject.save!
    end
  end
end

gemfile

group :development, :test do
  gem 'byebug'
  gem 'rspec-rails'
end

group :test do
  gem 'capybara'
end

spec_helper.rb

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'capybara/rspec'

我明白了

需要有一个用户已经在数据库中创建的水豚参考

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'capybara/rspec'
