会话控制器的 Rspec

Question

我正在尝试为会话控制器编写一个 rspec。但我做不到。

我想测试控制器的有效和无效的有效属性。如果为特定用户传递了有效属性，则测试应通过，如果为给定用户传递了无效属性，则测试应失败。

require 'rails_helper'
RSpec.describe SessionsController, type: :controller do
let(:user)  { User.create(name: "some",email: '[e-mail]', password: 'rous',password_confirmation: "some") } 
describe "get login path" do
it "login page" do
get :new
expect(response).to render_template('sessions/new')
end
end
describe "valid attributes" do
it "create a session" do 
post :create, session: { email: user.email, password: user.password }
expect(response.status).to render_template('/users/@user.id')
end
end
describe "invalid attributes" do
it "does not create a session" do 
post :create, session: { email: user.email, password: "12345" }
expect(response.status).to render_template('sessions/new')
end
end

describe "does not create a session" do
it "if email is empty" do 
post :create, session: {password: "some"}
expect(response.status).to render_template('sessions/new')
end
it "if password is empty" do 
post :create, session: {email: "[e-mail]"}
expect(response.status).to render_template('sessions/new')
end
end
end

描述"无效属性">

和"有效属性"无法正常工作。

如果电子邮件/密码错误，用户将重定向到会话#新页面。

如果电子邮件和密码正确，用户应重定向到user_path即用户显示页面。

您实际上应该在此处使用请求或功能规范，因为它们驱动整个堆栈。您不仅要测试控制器是否重定向到某个位置 - 您真的想测试重定向到某个位置并使用户登录。最好不要戳内部或嘲笑您应该首先测试的实际身份验证过程。

RSpec 和 Rails 团队都不鼓励为新应用程序编写控制器测试/规范。测试应用程序的行为。不是它如何完成它的工作。

require "rails_helper"
RSpec.feature "User sign in", type: :feature do
let!(:user) { FactoryBot.create(:user) }
scenario "User signs in with valid crentials" do
visit "/sessions/new"
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign In"
expect(page).to have_text "You have been signed in"
end
scenario "User signs in with invalid crentials" do
visit "/sessions/new"
fill_in "Email", with: user.email
fill_in "Password", with: "nottherightpassword"
click_button "Sign In"
expect(page).to_not have_text "You have been signed in"
expect(page).to have_text "Invalid email or password"
end
end

或者作为较低级别的请求规范：

require "rails_helper"
RSpec.describe "Sessions", type: :request do
let!(:user) { FactoryBot.create(:user) }
describe "POST /sessions" do
context "with valid credentials" do
it "redirects the user" do
post '/sessions', 
params: { session: { email: user.email, password: user.password } }
expect(response).to redirect_to user_path(user)
follow_redirect!
expect(response.body).to include("You have been signed in")
end
end
context "with invalid credentials" do
it "does not redirect the user" do
post '/sessions', 
params: { session: { email: user.email, password: "nottherightpassword" } }
expect(response).to_not redirect_to user_path(user)
expect(response.body).to include("Invalid email or password")
end
end
end
end
