Hi, Im trying to test the following method: def notice 65 userAgent = request.env[‘HTTP\_USER\_AGENT’] 66 67 if userAgent.index(‘MSIE 7.0;’) != nil 68 @ie7 = true 69 elsif userAgent.index(‘MSIE 6.0;’) != nil 70 @ie6 = true 71 end 72 73 if (@ie6) 74 render :action=\> “notice”, :layout =\> false 75 else 76 redirect\_to :controller =\> “home”, :action =\> “index” 77 end 78 end the problem im having is that i cant seem to find a way of setting the user agent before it goes into the method and checks the type of browser being used. im sure this is something trivial involving a mock but its just proving to be a bit illusive to me ☹ Cheers, Chris ---

If you’re in a functional test and have a TestRequest object named @request, you could do this: ``` @request.env["User-Agent"] = "whutever" # I think that header ``` name is right… You can set arbitrary headers like that. –Jeremy On Wed, Jun 25, 2008 at 4:31 AM, Chris G.

You need to read up on Rails’ functional testing. Google has a lot of good resources! 🙂 [http://www.google.com/search?client=safari&rls=en-us&q=rails+functional+testing&ie=UTF-8&oe=UTF-8](http://www.google.com/search?client=safari&rls=en-us&q=rails+functional+testing&ie=UTF-8&oe=UTF-8) –Jeremy On Thu, Jun 26, 2008 at 3:20 AM, Chris G.
