My Rails application uses the SERVER\_NAME environment variable to  
decide how to display some of the web pages.

I want to do integration testing with this application but I do not  
see how to force the request object’s environment variable SERVER\_NAME  
to a particular value.

I would like to do something like this in the integration test file

request.env[“SERVER\_NAME”] = “[www.example.com](http://www.example.com)”

This does not work. Any suggestions?
