Expected prawn to match ""

Hi, I’m getting this failure on the tests in chapter 1 page 22

1) Failure:
test_pdf_request_sends_a_pdf_as_file(NavigationTest) [/Users/michaeljohnmitchell/Sites/pdf_renderer/test/integration/navigation_test.rb:12]:
Expected /Prawn/ to match "".

I don’t understand why it’s expecting it to match ”” when the test is asserting that it matches page.body

test 'pdf request sends a pdf as file' do
   visit home_path
   click_link 'PDF'

assert_equal 'binary', headers['Content-Transfer-Encoding']
  assert_equal 'attachment; filename="contents.pdf"',
    headers['Content-Disposition']
  assert_equal 'application/pdf', headers['Content-Type']
  assert_match /Prawn/, page.body
end

I have the same issue. I’d like to know if anyone has finished this integration test successfully.

Same error.

Try using page.source instead of page.body.
