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: test_mechanize_response_read_error.rb
    path of file: ./repos/mechanize/test
    
    the code of the file until where you have to start completion: require 'mechanize/test_case'

class TestMechanizeResponseReadError < Mechanize::TestCase

  def setup
    super

    @error = 'error message'
    @response = Response.new
    @response['content-length'] = 3

    
  def test_force_parse
    @response['content-type'] = 'text/html'
    uri = URI 'http://example/'

    e = Mechanize::ResponseReadError.new @error, @response, @body_io, uri, @mech

    page = e.force_parse

    assert_kind_of Mechanize::Page, page
    assert_equal 'body',            page.body
    assert_equal @mech,             page.mech
  end
