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: underline_panels_test.rb
    path of file: ./repos/view_components/test/components/alpha
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require "components/test_helper"

class PrimerUnderlinePanelsTest < Minitest::Test
  include Primer::ComponentTestHelpers

  def test_renders_panels_and_tab_container
    render_inline(Primer::Alpha::UnderlinePanels.new(label: "label")) do |component|
      component.with_tab(selected: true, id: "tab-1") do |tab|
        
    
  def test_puts_actions_first_if_align_right_and_actions_exist
    render_inline(Primer::Alpha::UnderlinePanels.new(label: "label", align: :right)) do |component|
      component.with_tab(selected: true, id: "tab-1") do |tab|
        tab.with_text { "Tab 1" }
        tab.with_panel { "Panel 2" }
      end
      component.with_tab(id: "tab-2") do |tab|
        tab.with_text { "Tab 2" }
        tab.with_panel { "Panel 2" }
      end
      component.with_actions do
        "Actions content"
      end
    end
