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: scalar_test.rb
    path of file: ./repos/rails-graphql/test/graphql/type
    
    the code of the file until where you have to start completion: require 'config'

class GraphQL_Type_ScalarTest < GraphQL::TestCase
  DESCRIBED_CLASS = unmapped_class(Rails::GraphQL::Type::Scalar)

  def test_valid_input_
    
  def test_inspect
    DESCRIBED_CLASS.stub(:name, 'GraphQL::TestScalar') do
      assert_equal('#<GraphQL::Scalar Test>', DESCRIBED_CLASS.inspect)
    end

    DESCRIBED_CLASS.stub(:name, 'GraphQL::Test') do
      assert_equal('#<GraphQL::Scalar Test>', DESCRIBED_CLASS.inspect)
    end
  end
