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: style_spec.rb
    path of file: ./repos/shoes4/shoes-core/spec/shoes/common
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'spec_helper'

describe Shoes::Common::Style do
  include_context "dsl app"
  let(:blue) { Shoes::COLORS[:blue] }

  class StyleTester
    include Shoes::Common::Visibility
    include Shoes::DimensionsDelegations
    include Shoes::Common::Style
    include Shoes::Common:
    
    def initialize(app, styles = {})
      @app = app # needed for style init
      @dimensions = Shoes::Dimensions.new(@app, left: 15)

      # Would normally be done by UIElement#initialize
      style_init(styles, key: 'value')
      update_dimensions
    end

    def click(&arg)
      @click = arg
    end

    def click_blk
      @click
    end

    def update_visibility
    end
