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: repository_spec.rb
    path of file: ./repos/gitlabhq/spec/models
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'spec_helper'

RSpec.describe Repository, feature_category: :source_code_management do
  include RepoHelpers

  before do
    stub_const('TestBlob', Struct.new(:path))
  end

  let_it_be(:user) { cre
    
  def expect_to_raise_storage_error
    expect { yield }.to raise_error do |exception|
      storage_exceptions = [Gitlab::Git::CommandError, GRPC::Unavailable]
      known_exception = storage_exceptions.select { |e| exception.is_a?(e) }

      expect(known_exception).not_to be_nil
    end
  end
