Rails

i am working through the Beginning Ruby on Rails Ecommerce book and on
page 101 where it is talking about integration tests, i run
test/integration/book_test.rb and it fails giving me the following
error message:

  1. Failure:

    looking through the code, i clearly see that “Ruby for Dummies” is in
    fact in there and I also see that it is wrapped inside of “td” html
    tags… so why is this test failing? i thought there might have been a
    typo in my code somewhere, so i downloaded the sample code from the
    site and i still got the same error message.

    i’m new to TDD so i’m not really sure where to start troubleshooting
    this

The assert_tag is broken in Rails, you must edit the

vendor/rails/actionpack/lib/action_controller/test_process.rb file and
change the implementation of html_document as follows:

def html_document
@html_document ||= HTML::Document.new(@response.body)
HTML::Document.new(@response.body)
end

Actually, the patch removes the @html line. it should read

 def html_document
     HTML::Document.new(@response.body)
 end

Oops, my bad. Overlooked the - and + there. Try the fix for 1.1.6 and
see if
it works. If it does not you can always revert back to the old code.

The latest version has deprecated the assert_tag, assert_select is the
replacement. So I don’t think that fix is for latest version.

Is this for the latest version of rails though? i’m not running edge
or anything, just 1.1.6
