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: branch_test.rb
    path of file: ./repos/rugged/test
    
    the code of the file until where you have to start completion: # encoding: UTF-8
require "test_helper"

class BranchTest < Rugged::TestCase
  def setup
 
    
  def test_create_unicode_branch_nfc
    branch_name = "\xC3\x85\x73\x74\x72\xC3\xB6\x6D"

    new_branch = @repo.create_branch(branch_name, "5b5b025afb0b4c913b4c338a42934a3863bf3644")
    refute_nil new_branch

    assert_equal branch_name, new_branch.name
    assert_equal "refs/heads/#{branch_name}", new_branch.canonical_name

    refute_nil @repo.branches[branch_name]
  end
