Here’s the controller:

class SayController \< ApplicationController  
def hello  
@name = ‘john’  
end  
end

Here’s the view template:

 Say Hello 
# Hello, \<%= @name%\>

Here’s the functional test:

require File.dirname( **FILE** ) + ‘/…/test\_helper’

class SayControllerTest \< ActionController::TestCase  
def test\_hello  
get :hello  
assert\_template “say/hello”  
assert\_response :success  
assert\_tag :tag =\> “h1”, :child =\> /john/  
end  
end

It hits a case where Rail uses Kernel#loop, so I implemented it.

It uncovered a couple of problems with how we implemented Hash#each\*.  
Ruby hashes can be modified from within the blocks that we yield to, but  
we were using foreach () to iterate over the underlying  
Dictionary\<object, object\>.

Both of these fixes are on my machine, and I’ll submit later once I get  
a connection back to corpnet.

We have WEBrick nearly running now. We are currently blocking on  
IO#select.

Thanks,
