However, the #post method won't allow you to set a different controller than the one in the @controller instance variable that's defined in your test's #setup. Well, by looking at how the <a href="http://api.rubyonrails.org/classes/ActionController/TestProcess.html#M000046">#process method</a> works, you can see that it just grabs the controller from @controller. Redefine that, and you're good to go: <br /><code>old_controller = @controller <br />@controller = LoginController.new <br />post( <br /> :attempt_login, <br /> {:user => {:name => 'joe', :password => 'password'}} <br />) <br />@controller = old_controller</code> <br />If you have several login methods, such as a #login_admin and #login_regular, you could make a wrapper to reduce duplication: <br /><code>def wrap_with_controller( new_controller = LoginController ) <br /> old_controller = @controller <br /> @controller = new_controller.new <br /> yield <br /> @controller = old_controller <br />end <br /> <br />def login_admin <br /> wrap_with_controller do <br /> post( <br /> :attempt_login, <br /> {:user => {:name => 'root', :password => 'password'}} <br /> ) <br /> end <br />end <br /> <br />def login_regular <br /> wrap_with_controller do <br /> post( <br /> :attempt_login, <br /> {:user => {:name => 'joe', :password => 'password'}} <br /> ) <br /> end <br />end</code> <br /> Tue, 24 Oct 2006 18:54:12 GMT http://snippets.dzone.com/posts/show/2880 moneypenny ()
