You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: random_integration_test.rb
    path of file: ./repos/mushroom-observer/test/integration/capybara
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require("test_helper")

class RandomIntegrationTest < CapybaraIntegrationTestCase
  def test_the_homepage
    login(users(:zero_user))
    
    
  def test_login_and_logout
    login!(rolf)

    visit("/info/how_to_help")
    assert_selector("body.info__how_to_help")
    assert_no_link(href: "/account/login/new")
    assert_link(href: "/account/logout")
    assert_link(href: "/users/#{rolf.id}")

    first(:link, text: "Logout").click
    assert_selector("body.login__logout")
    assert_link(href: "/account/login/new")
    assert_no_link(href: "/account/logout")
    assert_no_link(href: "/users/#{rolf.id}")

    click_link(text: "Introduction")
    assert_selector("body.info__intro")
    assert_link(href: "/account/login/new")
    assert_no_link(href: "/account/logout")
    assert_no_link(href: "/users/#{rolf.id}")
  end
