Rspec 用于会话控制器

Question

我正在尝试为会话控制器编写 rspec。但是我做不到。

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

require 'rails_helper'

RSpec.describe SessionsController, type: :controller do

   let(:user)  { User.create(name: "some",email: 'other@example.com', 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: "some@gmail.com"}
            expect(response.status).to render_template('sessions/new')
        end

     end
end

描述 "invalid attributes" 和 "valid attributes" 工作不正常。

如果 email/password 错误，用户将重定向到 session#new 页面。

如果电子邮件和密码正确，用户应该重定向到 user_path 即用户显示页面。

您真的应该在这里使用请求或功能规范，因为它们驱动整个堆栈。您不仅想测试您的控制器是否重定向到某个地方 - 您真的想测试它重定向到某个地方并让用户登录。最好不要深入内部或模拟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 tests/specs。测试应用程序的行为。不是它的工作方式。

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

Rspec 用于会话控制器

Rspec for sessions controller
