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
