Hello,

I am getting an error whenever I try to use assert\_select in the  
following test:

def test\_should\_have\_add\_link\_selected\_on\_new  
get :new, :user =\> @current\_user.screen\_name  
assert\_response :success  
assert\_select “input#scheduled\_post\_append\_to\_post[checked]”,  
“checked”  
end

I get the same error when calling the single parameter version of  
assert\_select:  
assert\_select “input#scheduled\_post\_append\_to\_post”

The error is:

ArgumentError: wrong number of arguments (6 for 2)

/usr/lib/ruby/gems/1.8/gems/mocha-0.4.0/lib/mocha/test\_case\_adapter.rb:19:in  
`run’

I am clearly not passing it 6 args. I have tried to write other tests  
using assert\_select and this error is thrown consistently.

I found one other unresolved thread when searching the archives:  
[http://thread.gmane.org/gmane.comp.lang.ruby.rails/128719/focus=128724](http://thread.gmane.org/gmane.comp.lang.ruby.rails/128719/focus=128724)  
and I have contacted the user to see if he found a resolution but I  
would appreciate it if anyone else has any ideas how to resolve this  
issue.

Thanks,  
-Jesse

Not sure this is helpful, but sounds like the HTML parser that  
assert\_select using is having difficulty with the response. Might help  
to do a “puts @response.body” before the assert\_select to examine it

Hope this helps

Just answering my own question from a while back.

It turns out at some point along the way someone had installed  
ruby-htmltools ( [http://bike-nomad.com/ruby/](http://bike-nomad.com/ruby/) ) in our project. This  
library contains an HTML:Tag class that was clobbering the HTML:Tag  
class in /action\_controller/vendor/html-scanner/html .

Removing this library cleared up the problem.
