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: github_output.rb
    path of file: ./repos/brakeman/test/tests
    
    the code of the file until where you have to start completion: require_relative '../test'

class TestGithubOutput < Minitest::Test
  def setup
    @@report ||= github_report
  end

  def test_report_format

    
  def test_report_format
    assert_equal 43, @@report.lines.count, "Did you add vulnerabilities to the Rails 6 app? Update this test please!"
    @@report.lines.each do |line|
      assert line.start_with?('::'), 'Every line must start with `::`'
      assert_equal 2, line.scan('::').count, 'Every line must have exactly 2 `::`'
    end
  end
