Write an integration test for all the layout links, including the proper behavior for logged-in and non-logged-in users

Question

im working with railstutorial.org, im currently at 9th chapter, doing exercises. I have to write an integration test for all the layout links, including the proper behavior for logged-in and non-logged-in users. There's an exercise: Write an integration test for all the layout links, including the proper behavior for logged-in and non-logged-in users. Hint: Add to the test in Listing 5.25 using the log_in_as helper.

This is 5.25 Listing:

require 'test_helper'

class SiteLayoutTest < ActionDispatch::IntegrationTest

  test "layout links" do
    get root_path
    assert_template 'static_pages/home'
    assert_select "a[href=?]", root_path, count: 2
    assert_select "a[href=?]", help_path
    assert_select "a[href=?]", about_path
    assert_select "a[href=?]", contact_path
  end
end

This is the line i came up with to solve the exercise:

assert_select "a[href=?]", login_path || users_path

My tests are green, but did I am not sure if I understood the exercise right, and If i solved it.

So my question is, how do I write the test described in the exercise, thanks

You need to add something like this:

# Not logged in so a "Login" link will be present
assert_select "a[href=?]", login_path
# Login
log_in_as(@user)
# Go to root
get root_path
# Now logged in so a "Login" link won't be present
assert_select "a[href=?]", login_path, count: 0
# Now logged in so a "Logout" link will be present
assert_select "a[href=?]", logout_path
# Now logged in so a "Users" link will be present
assert_select "a[href=?]", users_path
# Now logged in so a "Accounts" link will be present
assert_select 'a[href=?]', '#', text: 'Accounts'

Don't forget to include the following just after class SiteLayoutTest < ActionDispatch::IntegrationTest :

def setup
  @user = users(:michael)
end

I am working through this rails tutorial as well. Here is the full test I came up with. I may have went a bit extreme here, but the exercise does state that all links should be tested both logged in and logged out. This includes the user's profile and Settings links at user_path and edit_user_path respectively. One step that helped me was to actually look at the site both as a logged in and non-logged in user and even pull up the source to determine the full list of links as indicated by the a href tags in the source. Also, make sure you get root_path after your log_in_as(@user) . This will save you the confusion and headache that I suffered.

test "layout links for logged-in and non-logged-in users" do
  get root_path
  assert_template 'static_pages/home'
  assert_select "a[href=?]", root_path, count: 2
  assert_select "a[href=?]", help_path
  assert_select "a[href=?]", about_path
  assert_select "a[href=?]", contact_path
  assert_select "a[href=?]", signup_path
  assert_select "a[href=?]", login_path
  log_in_as(@user)
  get root_path
  assert_select "a[href=?]", root_path, count: 2
  assert_select "a[href=?]", help_path
  assert_select "a[href=?]", about_path
  assert_select "a[href=?]", contact_path
  assert_select "a[href=?]", login_path, count: 0
  assert_select "a[href=?]", users_path
  assert_select "a[href=?]", logout_path
  assert_select "a[href=?]", "#", text: "Account"
  assert_select "a[href=?]", user_path(@user)
  assert_select "a[href=?]", edit_user_path(@user)
end

My steps are setup a user, test for layout links before login, use log_in_as helper to login the user, use follow_redirect! to actually visit the redirect page, then test for layout links after login.

This is my code:

require 'test_helper'

class SiteLayoutTest < ActionDispatch::IntegrationTest

  def setup
    @user = users(:michael)
  end

  test "layout links" do
    get root_path
    assert_template 'static_pages/home'
    assert_select "a[href=?]", root_path, count: 2
    assert_select "a[href=?]", help_path
    assert_select "a[href=?]", about_path
    assert_select "a[href=?]", contact_path
    assert_select "a[href=?]", signup_path
    get signup_path
    assert_select "title", full_title("Sign up")
    assert_select "a[href=?]", login_path
    get login_path
    assert_select "title", full_title("Log in")
    log_in_as(@user)
    assert_redirected_to @user
    follow_redirect!
    assert_select "h1", @user.name
    assert_select "a[href=?]", root_path, count: 2
    assert_select "a[href=?]", help_path
    assert_select "a[href=?]", about_path
    assert_select "a[href=?]", contact_path
    assert_select "a[href=?]", users_path
    assert_select "a[href=?]", user_path(@user)
    assert_select "a[href=?]", edit_user_path(@user)
    assert_select "a[href=?]", logout_path
  end
end
