  # Some generator-related assertions:
  #   assert_generated_file(name, &block) # block passed the file contents
  #   assert_directory_exists(name)
  #   assert_generated_class(name, &block)
  #   assert_generated_module(name, &block)
  #   assert_generated_test_for(name, &block)
  # The assert_generated_(class|module|test_for) &block is passed the body of the class/module within the file
  #   assert_has_method(body, *methods) # check that the body has a list of methods (methods with parentheses not supported yet)
  #
  # Other helper methods are:
  #   app_root_files - put this in teardown to show files generated by the test method (e.g. p app_root_files)
  #   bare_setup - place this in setup method to create the APP_ROOT folder for each test
  #   bare_teardown - place this in teardown method to destroy the TMP_ROOT or APP_ROOT folder after each test
