My app, relies on request.domain to display some data according to the  
domain.

However during RSpec tests, the request.domain is set to “test.host”. Is  
there a way I can manually set it for the test environment?

Thanks for your tip

Yes, you can do that, for example I do it like this:

it “should do something”  
request.headers[“Host”] = “[microsoft.com](http://microsoft.com)”  
get :index  
response.should render\_template(“public/404.html”)  
response.headers[“Status”].should == “404 Not Found”  
end

Not all is required, but you get the idea ;).
