Tests which use assert_select fail in 2.3.0 RC1 when upgrading an app

I doubled checked and it looks like HTML "should" be autoloading correctly. I'm really surprised that this happens with "rake", it would more commonly happen if you ran you test standalone.

Can you try adding "require 'html/document'" to the top of your tests (this is not the correct solution). I'm just hoping that fixes it and we can confirm its an autoloading issue.

I think this is getting us closer.... now I get:

/Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in gem_original_require': no such file to load -- html/document (MissingSourceFile)

from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require'
from /Library/Ruby/Gems/1.8/gems/activesupport-2.3.0/lib/active_support/dependencies.rb:158:in `require'

from /Library/Ruby/Gems/1.8/gems/rake-0.8.3/lib/rake/rake_test_loader.rb:5

This happens when I place the require just below the test_helper require as well as if I place it inside the class block.

So perhaps the autoload can't locate the class properly based on the html/document reference?

I found another symptom which might be causing this. The first controller failure resulted in this stacktrace:

test_changelog_do_not_exist(Admin::AboutControllerTest): NoMethodError: undefined method id2name' for {:instance_writer=>false}:Hash

Every controller after that failed with NameError: uninitialized constant HTML::Document

It appears that the Money gem may be overstepping some rails calls thus causing this issue.

I believe it was caused because my app uses ActiveMerchant as a plugin. As a result, I had a config.gem "money" requirement. When I removed that requirement, the cattr_accessor errors went away, as well as the HTML::Document issues. I believe it was a collision between the 2, as I couldn't replicate it in a fresh app.

My apologies that this isn't purely a Rails issue. This does point to a potential conflict that only appears to have been introduced in 2.3.0, but as to whether that is a Money gem/Active Merchant issue or a Rails issue, I'll leave as an open question.

Had the same issue, updating the Money gem to 2.0.0 fixed it.

Also using ActiveMerchant as a gem v1.4.1 eliminates the issue. It looks like the conflict is only between older versions of ActiveMerchant/Money & Rails 2.3.0. Updating both eliminates the conflict.
