Generate integration tests to write tests for index pages

$ rails generate integration_test users_index
      invoke  test_unit
      create    test/integration/users_index_test.rb

And test/integration/users_index_test.rb

require 'test_helper'

class UsersIndexTest < ActionDispatch::IntegrationTest

  def setup
    @user = users(:michael)
  end

  test "index including pagination" do
    log_in_as(@user)
    get users_path
    assert_template 'users/index'
    assert_select 'div.pagination'
    User.paginate(page: 1).each do |user|
      assert_select 'a[href=?]', user_path(user), text: user.name
    end
  end
end

solution

Looking at the above picture, the indentation is off (lana: on line 11), but this seems to be the cause. Apparently, if there is any deviation, it will not be treated as a column and an error will occur. Also, all tests fail It is because the pre-fixture data is read in the pre-processing of each test. Even so, it's hard to be crushed for 5 hours with this one deviation.
