I have a actionmailer model that send the user a URL to the website  
for account activation. In my unit tests for the model I want to  
ensure that the correct URL is being generated. In the test I have  
the following:

assert sent.body.include? new\_account\_activation\_url(:activation\_code  
=\> user.perishable\_token)

When I run the test, I get undefined method  
‘new\_account\_activation\_url’. ‘new\_account\_activation\_url’ works fine  
in the model so I know it is not a routing problem. I assume that I  
need to include some helper to get this to work but I am not sure what  
to include.

Any ideas?

Thanks!
