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: test_app_generator.rb
    path of file: ./repos/hyper-react/lib/generators/reactive_ruby/test_app
    
    the code of the file until where you have to start completion: require 'rails/generators/rails/app/app_generator'

module ReactiveRuby
  class TestAppGenerator < ::Rails::Gen
    
    def generate_test_app
      opts = options.dup
      opts[:database] = 'sqlite3' if opts[:database].blank?
      opts[:force] = true
      opts[:skip_bundle] = true

      puts "Generating Test Rails Application..."
      invoke ::Rails::Generators::AppGenerator,
        [ File.expand_path(test_app_path, destination_root) ], opts
    end
